2006 3 SERIES SEDANS AND SPORTS WAGON:
The New 3 Evolves with All-Wheel Drive
and 5-Door Versatility

As just about everyone who cares about cars and driving knows, the BMW 3 Series is an icon – and for many reasons: Among them are its style; its quality; its unique combination of performance, practicality and European luxury in a compact package.

Yet above all, the 3 Series’ iconic status derives from how it drives. Over the decades, the 3 Series has always been remarkably agile and pleasurable to drive, while also offering comfort and everyday usability. Though many have tried and are still trying, no one else quite knows how to match this constellation of attributes.

Leading off a new generation of the 3 Series, the E90 Sedans made their debut last spring. Expressing the classic 3 Series concept in an entirely new, 5th-generation form, they introduced –

• An all-new design that masterfully blends 3 Series character and tradition with progressive esthetics and enhanced functionality.
• All-new engines that retain the unique smoothness and sound character of BMW’s inline 6-cylinder format while offering more power, greater torque, even more refined delivery of power, and improved fuel efficiency.
• All-new suspension that combines the refined road manners of larger, more costly BMWs with the agility of the more compact 3 Series…plus innovations in steering, brakes and stability systems as well.
• Even greater body rigidity, more efficient aerodynamics and advances in the management of accident-impact forces.
• More space for rear-seat passengers and cargo.
• Greater luxury and convenience, encompassing numerous features previously offered only in the 5, 6 and 7 Series.
• New safety features, encompassing rear Head Protection and other advances. (Front-seat Head Protection was standard in the predecessor Sedans.)

As the first models of this new 3 Series for the U.S., the E90 325i and 330i Sedans entered production in March 2005 as 2006 models. Now, coming from BMW production plants since September 1, ‘05, three more models join the new 3 Series:
• 325xi and 330xi Sedans, featuring BMW’s innovative xDrive all-wheel drive system and specific configurations of standard and optional equipment.
• The 325xi Sports Wagon, adding 5-door wagon versatility and xDrive all-weather, any-road capability to the 3 Series formula of driving pleasure and practicality.

New through and through,
yet firmly grounded in 3 Series tradition
From their low, wind-slicing front end through an upswept silhouette to a high trunklid or large-area tailgate that enhances aerodynamics and cargo space, the ’06 3 Series Sedans and Sports Wagon are a logical progression from their E46-platform predecessors. Not only does the first glance tell you that these are BMWs; it also tells you clearly that they are 3 Series.

Incrementally larger and roomier,
yet still truly compact
Compared to their predecessors, these new models grow in nearly every dimension. Wheelbase is up by 1.4 inches; length is 2.2 in. greater for the Sedans, 1.9 in. for the Sports Wagon; width is up by fully 3 in.; and the new models are 0.8 in. (Sedans) or 1.0 in. (Sports Wagon) taller. These increases in exterior dimensions translate into greater safety capabilities, enhanced luxury and comfort equipment, and greater passenger and cargo space: shoulder room, front head room, rear knee room, and EPA passenger and cargo volumes are all up, as shown in the table below. Yet the 3 Series in no way abandons its tradition of compact exterior dimensions. Here’s a summary of the new Sedans‘ dimensions vs. those of their predecessors:

2005 2006 Difference
Wheelbase, in. 107.3 108.7 +1.4
Track, front/rear, in. (standard wheels) 57.9/58.4 59.1/59.6 +1.2/1.2
Length, in. 176.0 178.2 +2.2
Width, in. 68.5 71.5 +3.0
Height, in.
(without Sport Package) 55.1 55.9 +0.8
Weight, lb. (with automatic transmission):
325i Sedan 3307 3351 +43
330i Sedan 3362 3450 +88
Weight distribution, front/rear, %:
325i Sedan 50.9/49.1 50.7/49.3 0.2
330i Sedan 50.6/49.4 51.1/48.9 0.5
Shoulder room, front/rear, in. 54.4/54.2 55.4/55.1 +1.0/0.9
Head roof, front/rear, in. 37.0/37.4 37.4/37.1 +0.4/-0.3
Leg room, front/rear, in. 41.4/34.6 41.5/34.6 +0.1/–
Rear knee room, in. 30.9 31.7 +0.8
EPA interior volume, cu ft. 90.8 93.0 +2.2
EPA cargo volume, cu ft. 10.7 12.0 2 +1.3

The new Sports Wagon has the same wheelbase, tracks, length, width and height as the Sedans; its passenger volume is up from 90.7 to 92.6 cu ft. Cargo-volume measurements for the two model years are not precisely comparable, but new underfloor storage space results in an overall increase in the Wagon as well.

Technology and features:

The benchmark sports sedans
set a new benchmark
“Few cars have inspired as much competition as this family of perennial pacesetters,” raved Car and Driver in its January ’05 10Best awards, “and fewer still have resisted competition so successfully. What’s the 3 Series’ secret? Smooth 6-cylinder power, exemplary ergonomics, silky-smooth shifting, supple ride quality, eager responses, superb seats, and proportions that never look out of date.”

BMW’s overarching goal for the new 3 Series was to improve on all these qualities.

All-new 6-cylinder engines:
world’s first contemporary magnesium/
aluminum composite construction
These days, most 6-cylinder engines are V-6s. By contrast, BMW’s “sixes” are inline engines, noted for exceptional smoothness and unique sound. BMW customers and independent critics treasure them for these attributes; BMW decided to retain the inline-6 while developing it toward reduced weight, more compact dimensions and even more brilliant performance, smoothness and sound. An increase in fuel efficiency and even tighter control of emissions were also goals for the new engines.

The result of this quest is a new generation of 6-cylinder engines, with the BMW engine designation N52. Compared to its illustrious predecessor, the M54 family, the N52 achieves notable progress on all fronts:
• Greater power, 255 vs. 225 hp for 330i/xi models. This amounts to an impressive 85 hp per liter. The 325i/xi engine is up from 184 to 215 hp.
• Greater torque, 220 lb-ft. vs. 2143 for 330i/xi models, and even stronger torque delivery across the broad range of engine speeds. The 325i/xi engine develops 185 lb-ft., up from 175.
• Higher revving ability. The new engine’s redline is 7000 rpm, vs. 6500 for the predecessor.
• Superior fuel efficiency. EPA ratings are up for 8 of the 10 engine/transmission combinations; see the table below.
• Reduced weight – 22 lb. less. Yet had BMW engineers evolved the existing engine to meet their goals, it would have added about 30 lb.
• More compact – because there is just one external drive belt vs. the previous two, overall engine length is about an inch less.

Dynamic Efficiency: EPA mileage up for almost all versions,
along with greater performance

Here are some details of how this impressive progress has been achieved – over an engine that was already outstanding in all these respects.

Valvetronic variable valve lift. Already enhancing the performance and fuel efficiency of BMW’s V-8 and V-12 engines, this innovation now appears for the first time in a BMW 6-cylinder engine, and in evolved form. Valvetronic varies valve lift to a far greater degree than other variable-lift systems – so much, in fact, that it replaces the traditional engine throttle. Engine breathing is controlled entirely by the valves themselves.

The Valvetronic mechanism acts on the intake valves, imposing an additional control element between the camshaft lobe and rocker arm for each cylinder, called an intermediate follower. Upon contact by the lobe, this follower actuates a finger-type rocker arm and, in turn, the valve. The follower’s pivot point is positioned by an eccentric shaft, rotated by a servo motor in response to the driver’s accelerator-pedal movements; this varies the valve lift. The system’s advantages include:
• Greater efficiency. As a throttle closes, it poses a restriction to incoming air. Valvetronic eliminates this restriction, reducing “pumping losses.”
• More spontaneous engine response – again, because there is no conventional throttle.
• More power, because maximum valve lift can be higher than it could be with fixed valve lift.
• A “flatter” torque curve. Not only does the engine produce more torque; the torque peak occurs at a lower speed, 2750 rpm vs. the previous 3500.

Compared to the 1st-generation Valvetronic system, that of the N52 engine has evolved in several ways:
• Higher maximum engine speed, by making Valvetronic reciprocating parts more rigid.
• Maximum valve lift increased, contributing to the greater power output.
• Greater maximum valve acceleration. Less time is spent opening and closing the valves; thus they are effectively open longer, further reducing pumping losses.
• Phasing of intake valves. A given cylinder’s two intake valves now open at different rates, resulting in a more targeted, asymmetric distribution of the fuel/air mixture that enhances fuel economy under gentle driving conditions.

Additional developments contribute to the new engines’ performance:
• Combustion chambers have been refined.
• BMW’s VANOS variable valve timing has also evolved; the range over which it varies intake-valve timing has been increased by 10 degrees.
• 3-stage induction system (330i/xi engine only). BMW 6-cylinders have long had a 2-stage system, with one intake-path length for lower rpm, the other for higher rpm. By providing an additional “middle” stage, this system further optimizes torque and power delivery.
• Higher fuel-injection pressure, up from 3.5 to 5 bar (50.8 to 72.5 lb/sq in.); improves the injection spray, reducing emissions from a cold engine.
• All-new engine electronics to optimize engine behavior and performance under all operating conditions.

Unique new magnesium/aluminum
composite engine construction
Current BMW 4-wheel vehicles (i.e. not motorcycles) utilize three types of engine construction, all with aluminum cylinder heads:
• Regular-production 6-cylinder engines (3, 5, Z4, X3 and X5 Series) – aluminum block with cast-iron cylinder liners.
• V-8 and V-12 engines, new V-10 (5, 7 and X5 Series, M5) – aluminum block with integrally cast silicon-impregnated aluminum cylinder surfaces.
• M3 engine – cast-iron cylinder block.

With the N52 engine, BMW introduces a unique engine structure: magnesium/aluminum composite construction, the first in a contemporary automobile. Its all-new engine block consists of three major castings:
Bedplate (magnesium alloy ). This casting forms the lower portion of the block (crankcase). It is similar in concept to an element of some racing engines – as well as the 500-hp V-10 engine powering the new BMW M5.
Upper crankcase (magnesium alloy5). Joining the bedplate at the level of the crankshaft (main) bearings, this too is a weight-saving casting. Mounted onto the bedplate from above; combines with the bedplate to form the cylinder block’s ultra-rigid, yet remarkably light outer shell.
Insert (aluminum alloy). Forms the cylinders and their coolant passages. Analogous to the V-8, V-10 and V-12 blocks themselves, silicon particles are cast into this insert; a “soft honing” machine removes just enough of the aluminum to leave the crystals as ultra-hard cylinder surfaces.

How it goes together. First, the aluminum insert is cast by conventional methods. Then, during a newly developed die-casting method, the magnesium upper shell shrinks onto the insert while cooling; structural rigidity and stability are ensured by interlocking ribs where the two castings meet.

In the next step, the upper crankcase, consisting of magnesium shell and aluminum insert, is mounted onto the magnesium bedplate from above. The sintered-steel main bearings’ lower halves are in place in the bedplate, the upper halves in the upper crankcase. After the bedplate and upper crankcase have been bolted together, a liquid sealing compound is injected into a groove on the contact surface between the two components. Special aluminum bolts are used to attach parts, such as the engine mounting brackets, to the magnesium/aluminum castings.

As the “conventional” part of this construction, the cylinder head is of aluminum; however, the head of an inline 6-cylinder engine must be cast with great precision because its length implies relatively large contraction during the cooling-down process after casting. The casting process used here is called “lost-foam”; because all BMW gasoline engines since the 1960s have had aluminum heads, BMW’s experience in this regard is long and successful; BMW has used the lost-foam method for cylinder heads since 1997. Employing a polystyrene “dummy” of the head to form the mold into which the aluminum is poured, the process results in an extremely precise casting of this critical engine component.

Other weight-saving materials. Though the magnesium/aluminum composite crankcase construction is the most conspicuous example, other materials and production innovations also help pare weight from the N52 engine. One is the adoption of hollow camshafts, which save a remarkable 2.6 lb. Beginning as steel tubes, the camshafts are shaped in a hydroforming procedure, subjected from the inside to a water pressure of 4000 bar (58,000 lb./sq in.) against outer forms to achieve the cam profiles. All this takes place cold – nothing melts – and finally, the cams are polished to a finish quality of 1/1000 mm.

The engine’s camshaft cover is of weight-saving magnesium. And the chain camshaft drive – a high-durability, low-maintenance feature of all current BMW engines – has an aluminum chain tensioner that also saves weight. Instead of being a separate casting, the camshaft drive’s housing is integrally cast into the magnesium structure, eliminating a production step and sealing components. As a final weight-paring element, the exhaust headers’ flanges are formed from 2-mm-thick steel, significantly lighter than the 12-mm flanges used previously; for a secure seal of this steel to the aluminum head, graphite rings are employed.

Electric coolant pump. A conventional engine coolant (“water”) pump is driven by a belt, and always runs at a speed directly proportional to engine rpm. This innovation is electrically driven and electronically controlled according to the engine’s coolant and oil temperatures at any moment. Thus it runs only as much as needed, and in doing so consumes a maximum of 200 watts vs. up to 2 kilowatts (10 times as much) for a conventional pump. This pump has further benefits:
• By requiring less power, it contributes to the engine’s increased power output.
• Faster engine warmup, because it doesn’t circulate coolant when the engine is cold.
• Provides coolant circulation for the Heat-at-Rest feature now included in the climate control. (With a conventional coolant pump, this needs a separate electric pump.)
• By eliminating an external drive belt, makes the engine shorter.

Variable-volume oil pump. Conventional oil pumps, too, deliver oil in direct proportion to engine speed. To supply the VANOS system (which employs oil pressure to vary valve timing) at all speeds and temperatures without excess capacity at high engine speeds, BMW engineers developed a new type of oil pump. By varying the output of its pump element according to engine oil pressure, the engineers achieved a pump that always delivers sufficient pressure to lubricate the engine and operate VANOS, yet never pumps more oil than is necessary. Thus it –
• Contributes to usable power, by requiring less power from the engine.
• Doesn’t require a bypass to divert excess flow, which can be up to 80%. This also avoids possible excess oil temperatures and oil foaming.

Oil/coolant heat exchanger. Another feature that speeds engine warmup; during this phase it transfers heat from the coolant to the oil circuit. At high engine power and oil temperatures, it performs the reverse, transferring heat from the oil circuit to the coolant, from which the engine cooling system then removes excess heat.

325i/xi and 330i/xi: the two engine versions
In contrast to the initial European palette of 4-cylinder 320i, 6-cylinder 330i and 4-cylinder diesel 320d, the 3 Series launched in the U.S. with two models. Both use a 3.0-liter N52, equipped and calibrated for two levels of performance:

• 325i/xi – 215 hp @ 6250 rpm, 185 lb-ft. torque @ 2750 rpm
• 330i/xi – 255 hp @ 6600 rpm, 220 lb-ft. torque @ 2750 rpm.

Significant differences between the two engine versions are as follows:
• Whereas the 330 engine has the 3-stage induction system, the 325 unit has a single-stage intake manifold.
• Engine software differs between the two models.

6-speed manual transmission
A 6-speed manual transmission is standard on all models. The 330i Sedan and all AWD models employ the Type H unit found in other current 3-liter models; the 325i Sedan uses a somewhat lighter-duty version Type I. Compared to the already excellent earlier BMW manual transmissions, both units offer tangible customer benefits:
• Even more effective synchronization of shifting
• Lighter and more pleasing feel as the shift lever is moved from gear to gear
• Firmer engagement of gear once selected
• Sportier shifting, via shorter shift “throws” from neutral to each gear
• Use of lifetime transmission oil, which never needs to be changed
• “Clean bearings” design for main transmission bearings; protects bearings from contamination, ensures adequate lubrication at all times and therefore enhances durability.

6-speed STEPTRONIC automatic transmission
With the new models, the 3 Series joins the 5, 6, 7 and X5 V-8 models in offering a 6-speed automatic. Compared to the 5-speed unit it replaces, it’s fully 10% lighter, has a more efficient torque converter, actually operates with fewer internal clutches, and can reduce fuel consumption, particularly at cruising speeds when 6th gear is in frequent use.

As in all other current BMW automatics, the STEPTRONIC feature offers drivers a choice of Normal, Sport and Manual modes. Park, Reverse, Neutral and Drive ranges (P-R-N-D) are in the shift lever’s right gate. The Sport mode, in which shifts occur at higher engine speeds, is engaged by moving the lever leftward from D; from here, the Manual mode is engaged when the driver manually chooses a gear by tipping the lever forward (for downshifts) or rearward (for upshifts).


Improving on tradition:
all-new chassis engineering
In concert with the new and more powerful engines, an all-new chassis brings the benefits of BMW’s double-pivot front suspension to the 3 Series for the first time. Completely new 5-link rear suspension further perfects the 3 Series’ unique blend of agility and stability; chassis/body rigidity has been further improved, and run-flat tires are standard across the board. Four-wheel ventilated disc brakes have been refined extensively, and a new-generation Dynamic Stability Control adds an array of new functions.

Double-pivot front suspension. Though familiar from BMW’s larger models (5, 6 and 7 Series as well as the X3 and X5 Sports Activity Vehicles), the double-pivot front suspension concept is new to the 3 Series. It is a more elaborate system than that of the existing 3 Series, featuring two lower arms (hence the appellation “double-pivot”) that work in concert with the spring/shock-absorber strut. The system provides –
• Small positive steering offset, for best steering feel and control under all road conditions. The two arms don’t actually intersect; if you visually extend their axes to a point where they do intersect, you find a “virtual pivot point” that is ideal for achieving this result. (Steering offset is the “lever arm” through which road forces act on the suspension system.)
• Large steering caster, for outstanding stability in straight-line driving and excellent steering return action coming out of curves.
• Space for large brakes, by virtue of the two lower arms‘ arrangement.

Further advantages are found in the details:
• The trailing (forward) lower arm has a rubber/hydraulic cushion, which provides highly effective “compliance” for enhancing riding comfort.
• The transverse (rearward) lower arm is cushioned by a finely tuned rubber element that fosters direct and precise steering response in curves and corners.
• Extensive aluminum componentry in the RWD models, for low unsprung weight. This improves the suspension’s response to bumps and other road irregularities; it can markedly improve riding comfort and, on any irregular road surface, handling as well. In these models, aluminum components on each side include –
• Both lower arms (forged aluminum)
• Steering knuckle (also forged)
• Brake caliper (not part of suspension, but part of unsprung weight)
• Brake shield (a stamped piece; also not part of suspension, but part of unsprung weight).

In addition, the subframe that carries the front suspension of RWD models is of aluminum, as is the steering rack; these are not unsprung, but do contribute to overall weight reduction – and being up front, also to the “typical BMW” near-50/50 weight distribution. The new-design subframe adds rigidity, enhances steering precision and is also an integral element in the vehicle’s management of energy in a frontal crash.

Because their front suspension handles drive forces as well as those of steering, cornering and braking, the AWD “xi“ models have mostly steel components in this area.

New 5-link rear suspension
In its concept, this brand-new system could be described as a double-A-arm system with an additional lateral track rod; the upper and lower A-arms are actually two links each, their vertical positions differing. (This is analogous to the front suspension’s dual lower arms.) Advantages are extensive:
• As at the front, there is a virtual pivot point for each pair of links, giving the engineers similar freedom in optimizing the system’s geometry for best handling. Also as at the front, the axis connecting these virtual points is configured to ensure that driving, braking and road forces all act effectively on short leverage. The result is very precise handling, especially insensitive to road disturbances.
• Under cornering forces, the system controls geometry in such a way as to achieve great agility while also ensuring predictable, stable handling. These are fundamentally contradictory qualities; the degree to which they are mutually achieved is a measure of a suspension’s excellence.
• Contributing to this outstanding geometry is the wide and rigid basis on which the rear tires are “planted” on the road. The lateral links are extremely rigid too, as is the subframe.
• All suspension links connect to the subframe; no longer does any link pivot directly from the body structure. This further reduces the effects of road irregularities on riding comfort, and improves handling precision as well.
• Here too, a large and elaborate subframe enhances energy management in a crash – including the more severe rear-end impact that the new models are designed to withstand. (See safety engineering and features).

As always with BMWs, the final drive (differential) is also mounted to the subframe through rubber, creating acoustic decoupling that minimizes the transmission of driveline noises into the body. Widely spread mounts to the body, in an area where the body structure is particularly rigid, further help optimize the combination of precision and riding comfort.

The rear suspension system, subframe and brake calipers are all of steel.

Steering: evolution standard, revolution optional
The 3 Series’ engine-speed-sensitive variable-assist power rack-and-pinion steering system has generated universal praise; an auto magazine once described it as “nearly telepathic.” This standard steering system continues essentially unchanged, although with a somewhat less direct overall ratio of 16.0:1. Yet numbers don’t always tell the entire story, for the new suspension and subframe have actually sharpened the new models’ reaction to steering inputs.

The “revolution” here is the newly optional Active Steering, previously available on the 5 and 6 Series. For details on Active Steering, offered as a stand-alone option on the RWD models, see options.

Ventilated disc brakes:
upgraded dimensions, new technology
The brakes continue with ventilated cast-iron rotors all around, and aluminum calipers at the front as a contribution to balanced weight distribution. Braking power has been enhanced by larger diameters:
325i/xi – rear discs upgraded from 294 mm/11.6 in. to 300 mm/11.8 in.; front discs remain at 300/11.8.
330i – front discs upgraded from 325 mm/12.8 in. to 330/13.0; rear discs upgraded from 320/12.6 in. to 336/13.2.

A new Geomet steel coating eliminates rusting on portions of the rotors not swept by the brake pads. And in the context of Condition-Based Service, which comes to the 3 Series for the first time, there are separate front and rear wear sensors via which the mileage remaining on the front and rear pads can be displayed and appropriate service scheduled.

New-generation Dynamic Stability Control:
remarkable new braking functions
All BMW models are standard-equipped with Dynamic Stability Control, which provides a wide range of traction and stability functions.

While retaining all these functions, a new-generation DSC system, appearing for the first time in the new 3, adds a wide array of customer-relevant functions that make driving even safer and more pleasant. They are:
• Brake Fade Compensation. Brake fade occurs as the brakes heat up under hard use; a given degree of deceleration requires more pressure on the brake pedal. As brake temperature rises, this function automatically compensates by increasing the hydraulic pressure relative to pedal force.
• Brake Standby. When the driver lifts off the accelerator pedal abruptly, DSC recognizes that sharp braking may be about to occur and applies just enough pressure in the brake system to snug up the pads against the rotors. Thus by the time the driver’s foot reaches the brake pedal, the lag time normally resulting from bringing the pad to the rotor is eliminated, reducing stopping or deceleration distance.
• Brake Drying. Acting on input from the rain sensor (an element of the standard rain-sensing windshield wipers), the pads are periodically brought up to the rotors – just enough to eliminate any film of water between pads and rotors, but not enough to cause a brake application.
• Comfort Stop. Especially with an automatic transmission, unless the driver consciously eases off on the brake pedal, a jerk can occur as the vehicle comes to a stop. Comfort Stop eases off, making for smoother stops. Currently only in the rear-wheel-drive 325i and 330i models.
• Start-off Assistant. Briefly holds the vehicle when the brakes are released while stopped facing uphill. The driver can then start up without doing a ballet with the clutch, brake and accelerator (manual transmission) or rolling backward on a steep hill (automatic transmission).
• Modulated ABS function. “Analogized” control of the DSC brake valves makes the anti-lockup function (ABS) smoother. Instead of simply being fully on or off, application and release of these valves are now modulated.

All-new wheel designs;
all-season or performance tires, all run-flats
Maintaining a BMW tradition, each model offers a choice of standard or Sport Package wheel-and-tire equipment. Fresh wheel designs complement the new body design; standard 330i/xi wheels and tires are wider than before. Differentiated front/rear sizes are part of the 325i Sedan‘s Sport Package for the first time; the 330i Sedan‘s Sport Package includes 18-in. wheels for the first time and continues with differentiated front/rear sizes. Performance tires are also part of these RWD models‘ Sport Packages.

As an additional nuance of the new models, the AWD “xi“ models‘ Sport Packages come with all-season tires in equal front/rear sizes. In turn, the RWD models‘ more aggressive Sport Package wheels and tires are available as stand-alone options for the AWD models, giving their buyers the choice of emphasizing all-weather capabilities or dry-road performance.

For details on wheel designs, wheel and tire sizes, tire type and tire speed ratings, see the standard & optional features table.

All ‘06 3 Series Sedans and the Sports Wagon come standard with BMW’s run-flat system, which consists of self-supporting tires and wheel rims shaped to help keep a flat tire securely in place. In their design and construction, the tires are distinguished primarily by their sidewalls, which include specific inserts and highly heat-resistant rubber compounds. These features allow a deflated tire to maintain its essential shape and guidance characteristics for a considerable distance, so that when confronted with a flat tire the driver can continue on until reaching a convenient and safe place to have the tire replaced. All functions of Dynamic Stability Control remain fully active; a Flat Tire Monitor alerts the driver to the loss of tire pressure.

The new 3 Series Sedans and Sports Wagon have no spare tire. Under the trunk floor is a deep compartment providing about 1.75 cu ft. of additional storage space.


xDrive: BMW’s “intelligent” all-wheel drive system
The new 325xi and 330xi models incorporate BMW’s advanced xDrive AWD and traction system. xDrive operates as follows:
• Driving torque is always transmitted to the rear wheels, and most of the time to all four wheels.
• The portion of torque transmitted to the front wheels is controlled by a multi-disc clutch that can be fully open, fully engaged or at any degree of partial engagement in between. The torque split between rear and front wheels is thus steplessly variable.
• Engagement pressure on the multi-disc clutch is directed by an electronic control system in response to actual road and driving conditions.

xDrive doesn’t just optimize traction; it can also enhance both agility and stability on grippy as well as slippery road surfaces. Via the same type of logic that DSC employs to recognize and correct for excessive over- or understeer, xDrive adjusts the front/rear torque split to avoid these tendencies. If undesirable oversteer is sensed, the multi-disc clutch is completely closed, sending the maximum possible torque to the front wheels. If excess understeer is detected, xDrive opens the clutch completely, sending no driving torque to the front wheels. In the BMW tradition, the driver enjoys optimum vehicle dynamics under a wide range of driving and road conditions.

Germany’s authoritative auto motor und sport (March 2, ’05) described and commented on xDrive in a new 5 Series Sedan this way: “Normally, the 530xi runs with the accent on rear-wheel drive: 60% of torque to the rear wheels, 40% to the front, but pure rear-wheel drive at speeds of 180 km/h [112 mph] or more. When traction is lacking or the vehicle tends toward instability, the torque split changes lightning-fast.

“The driver doesn’t notice any of this going on – but he or she does realize that on a slick road, the 530xi is very easy to drive. It has a high degree of stability, plus very agile handling.” Such comments would of course apply equally to a 3 Series model with this remarkable AWD system.

The new exterior design:
3 Series tradition, newly expressed
The new 3 Series consistently reflects the new direction set by BMW design with the 7 Series in 2002 and evolved with the new 5 Series in ’04. At the same time, it is true to its heritage, radiating the dynamic presence that has increasingly characterized this Series with each new generation.

At the front. In this face of strong character, distinctively formed four-beam headlight units wrap around and taper to a precise point, emphasizing in the front view the vehicle’s width and in profile its short front overhang. With the Xenon Adaptive lights (optional 325i/xi, standard 330i/xi models), BMW’s distinctive and popular luminous rings function as additional parking lights and also illuminate when the headlights are on.

In profile: Sedans. There is much “swing” in the side view: the hood cut line, sloping upward and then continuing to become the beltline and on past the C-pillar; a strong character line corresponds to that of the previous 3 Series, but sets up a stronger convex/concave intersection. Taillights that wrap well around into the body sides form an esthetic “punctuation” while enhancing visibility of the vehicle from the side – an active-safety factor. 325i/xi Sedans have all-black side-window framing; 330i/xi models have chrome and black.
Sports Wagon. Identical from the A-pillars forward and using the same front doors, the Sports Wagon takes on its own (but consistent) character from the B-pillar rearward. The roofline and the side windows’ upper line taper downward while the beltline continues upward, creating an expressly sporty wagon profile. Standard roof rails add swing and function to the profile as well.

At the rear: Sedans. A graceful arc connecting the taillight edges through the integral spoiler’s lower edge is at the top; the top of the spoiler is the continuation of a line that begins in the C-pillar. Below the spoiler, the surface goes concave toward the license-plate recess. The trunk’s outer edges sweep down into the bumper, making a conveniently low loading height also a visual treat. Functional/esthetic shapes are sculpted into the lower bumper area to help organize airflow at the back of the vehicle.

Sports Wagon. The side beltline wraps around to become an across-the-tailgate character line just under the separately opening rear windows. At the top, an integrated roof spoiler forms a graceful conclusion to the roofline, helping smooth airflow and incorporating the 3rd brake light. Like the Sedan’s trunklid, the tailgate reaches down into the bumper for a low loading height.

Aerodynamics
Aerodynamically, this is the smoothest 3 Series yet. At 0.30, the rear-wheel-drive Sedans are a “point” better than the previous models’ 0.31; at 0.31, the Sports Wagon is also a point better than its predecessor. The overall shape of either body style is calibrated to maintain low aerodynamic lift at higher speeds; a visually interesting and also functional sharp edge at the taillights’ corners helps ensure efficient airflow at the rear.

Improved corrosion-proofing
and paint processes
In preparing to produce the new 3 Series, BMW has further developed its rustproofing and paint processes. The refinements include:
• Body shell now virtually fully galvanized, for further enhanced corrosion resistance. Standing behind this claim is BMW’s 12-year/unlimited-mileage Rust-Perforation Warranty.
• Pre-paint preparation further improved. Bodies for the new 3 are cleaned and prepared for priming in a new 12-zone process.
• Rotation dipping for pre-paint preparation and primer application. This improves the cleaning process, and means that primers and corrosion-proofing coats reach even more fully into the body’s nooks and crannies.

Thus the beauty of this new 3 Series will be satisfyingly durable.

Ergonomics and luxury: more space,
enhanced functionality, new elegance
In addition to greater space, the new 3 Series interior offers reduced noise levels, improved climate control and a host of new features – standard and optional – that enhance luxury and convenience. And the design of this new interior is just as fresh as the exterior.

As always in BMWs, the driver enjoys his or her experience at the wheel partly because BMW has designed the interior to optimize that experience. All operational and informational elements essential to driving are grouped on and around the steering wheel; although many aspects of the control layout are updated, the most central informational element remains the traditional pair of round analog instruments directly in front of the driver.

A sharp eye will note that the two front door panels differ: On the passenger side there’s a sloped vertical door pull; on the driver’s side, where the power-window controls are newly grouped on the armrest, the door pull is integrated into that armrest. Both front doors include large storage bins.

In a choice exclusive to the 3 Series, the instrument panel is offered in two forms: standard, with a single hood above the instrument cluster; and optional, with a double-wave theme creating a second hood over the optional Navigation/iDrive control display. With the latter configuration, there is also the iDrive controller between the front seats.

New automatic climate control
Though the existing 3 Series has excellent automatic climate control, the new models’ system offers an even higher level of performance, sophistication and features. New features include –
• Separate left and right temperature controls vs. the predecessors’ single temperature control.
• Temperature- and volume-controlled rear air outlets that give rear passengers greater control over their environment.
• Climate-controlled center console compartment.
• Mist sensor. Via the windshield wipers’ rain sensor, misting of the windshield is sensed visually and system operation adjusted to clear it up.
• Heat at Rest. Allows heating the interior for a limited time with the engine off. Familiar from larger BMW models but new to the 3 Series; facilitated by the engine’s electric coolant pump.
• Maximum a/c setting for rapid cool-down at a single touch of a button.
• Increased blower power means not only increased maximum cooling or heating power, but also quieter operation at the normal blower speeds that are now a smaller proportion of maximum.
• Further optimized design of ducts and outlets, also cutting airflow noise.
• Automatic reduction of blower speed when the vehicle comes to a stop, for yet another reduction in noise.
• Indirect airflow via outlets atop the dash, for pleasant, draft-free climatization (not for defrosting or demisting).
• Recall of individual users’ settings via Key Memory:
• Temperatures
• Manually selected air distribution (windshield, body-level, footwells)

Other thoughtful features continue from the previous system:
• Active-charcoal microfilter ventilation
• Bi-directional solar sensor for front compartment (takes into account the intensity and direction of solar heat in determining cooling of interior)
• Automatic recirculation control, with specific sensing capability for diesel exhaust.

Two audio systems, two subwoofers
As before, two audio systems are offered. One is the 10-speaker system that’s standard in 325i/xi models; the other is the acclaimed 13-speaker Logic7 system – optional in 325i/xi, standard in 330i/xi models and making its 3 Series debut. Both systems include two subwoofers in BMW’s patented positions, in cavities at the bases of the B-pillars (“under the front seats”).

To the 10 speakers of the 325i/xi standard system, Logic7 adds a center-fill speaker to the instrument panel and two midrange speakers in the rear doors; all speakers are upgraded. Logic7’s digital Surround Sound process provides uniquely realistic reproduction, generating a 360° sound field and accurately re-creating the acoustic intent of the original studio master.

Upholstery and trim:
standard wood, optional leather
Leatherette upholstery is standard in all models; leather is available in four colors, two of them new. Dark Burl Walnut trim is standard; lighter-tone Poplar Natural and aluminum trim are available at no extra cost. Following a lead set by the 5, 6 and 7 Series, new “galvanic” trim appears on the instruments‘ and Start/Stop button‘s outer rings and several other interior detail elements; this elegant material has a plastic core, with a true metallic surface applied galvanically in several layers and a clear top coat to protect against corrosion.

Seating choices, including
sport seats with adjustable backrest width
Height-adjustable, 6-way manual front seats are standard in 325i/xi models; 8-way power seats are optional in 325i/xi and standard in 330i/xi models. New are available sport seats with adjustable backrest width, a feature first seen in the M3 Coupe. Available in both Sedan models are split folding rear seats and an interior-to-trunk pass-through with ski bag.

New seating choices are only one amenity among the many enjoyed by drivers and passengers in the new 3 Series. Others include –
• Available auto-dimming interior and exterior mirrors, the latter offered on this Series for the first time.
• A digital compass, set into the interior mirror and included with the auto-dimming mirrors.
• A standard 2-way power moonroof with more opening area than before on the Sedans; on the Sports Wagon, an even larger dual-panel moonroof.
• Voice Command, included in the Navigation/iDrive option.
• Available Bluetooth interface for cellphones.
• Front and rear overhead consoles, each with separate left/right reading lights, Ambiance Lighting and other features. Predecessor models had an overhead console and Ambiance Lighting only at the front.
• Footwell lighting
• A fold-up rear center armrest.

Increased cargo space,
new trunk features in Sedans
Elimination of the spare tire and jack, possible because run-flat tires are standard across the board, has helped create approximately 12% more cargo space than before. Moreover, the official EPA measurement on which this claim is based does not include a deep well under the trunk floor that encloses about 134 cubic feet and offers a place to store smaller objects without worry of their moving around when the vehicle is in motion.

Sports Wagon interior and cargo area
Up front, the Sports Wagon offers the same accommodations as the Sedans, except as affected by the Wagon’s Panorama moonroof. Front and rear leg room are identical for the two body styles; front and rear head room are almost identical. The Wagon’s standard split folding rear seats offer essentially the same functions and benefits as those that are optional in the Sedan.

The big difference, of course, is aft of the rear seats, where in terms of load-carrying ability and versatility the Sports Wagon offers advantages not only over the Sedans, but also over its predecessor. As always with a new BMW – especially a new BMW Sports Wagon – the 325xi abounds with rational design and thoughtful details:
• High-lift tailgate, electrically released from remote or interior switch.
• Separately opening rear window, for convenient loading without opening the tailgate.
• Fully lined cargo area – floor, sides, back sides of rear seats – with luxurious, yet long-wearing carpet.
• Wider than that in the previous Wagon, and with straight, essentially vertical sides, the cargo area presents various cargo possibilities:
• 16.2 cu ft. of volume with the seats upright and cargo loaded to the top of the seats
• 24.8 cu ft. with the seats upright and cargo loaded to the ceiling
• 60.9 cu ft. with the seats folded and cargo loaded to the ceiling
• Luggage straps on the right side
• Bag holder at either side
• 12-volt accessory power outlet on the left-hand wall.
• Cargo cover, concealing cargo when the seats are upright; user has option of having cover rise when rear window or tailgate is opened (by tapping the release twice) or remaining in place (by tapping once).
• If, once raised, a rear-seat backrest is not fully locked into place, a red tab appears to help call users’ attention to it.
• A cargo net, carried in a roller assembly with the cargo cover, that can be mounted with the rear seats either upright or folded
• Red light at left bottom of tailgate, for safety; visible when tailgate is open.

A Cargo Compartment package, which offers additional storage configurations, is available as a BMW center-installed accessory.

Dual-panel Panorama Moonroof
With its large roof opening, this feature gives occupants almost the feeling of being in a convertible. The power glass roof consists of two panels, both of which can be tilted up at the rear. The forward, larger panel can also be slid open; together, their glass area is almost 6.5 square feet. Although the glass is effectively tinted, there is also a power-operated interior shade; 1-touch operation is provided for all motions, including that of the interior shade.

Safety engineering and features:
improving on a star performer
The existing 3 Series’ safety performance has long been recognized by authoritative, independent observers:
• After conducting its own offset crash test of a 3 Series Sedan for the March 11, ’99 issue, Germany’s authoritative auto motor und sport magazine concluded, “Occupant protection by the new 3 Series is already at such a high level that only marginal improvements can be imagined.”
• And in the U.S., the Insurance Institute for Highway Safety, after conducting its own crash test of the 3 Series Sedan, concluded simply, “A Best Pick.”

In developing the all-new vehicle structure, BMW’s safety engineers set out not just to match, but to improve on, the predecessors‘ excellent safety performance. Integrated into this overall goal were specific targets, including –
• Achieving 5 stars in the Euro-NCAP (New Car Assessment Program) offset frontal crash test
• Meeting the new U.S. FMVSS (Federal Motor Vehicle Safety Standard) 301, which specifies a brutal 50-mph rear-end offset crash. The impact is taken by 70% of the test vehicle’s width; not only must stringent injury criteria be met, but the fuel system must remain free of leaks.
• Meeting the new IIHS (Insurance Institute for Highway Safety) “SUV side-impact” test, in which an impact from a tall vehicle at 50 km/h (31.1 mph) is simulated.

Various engineering approaches toward the new 3’s even higher-performing structure included:
• Use of new high-strength steels in the large-section structural elements.
• Targeted application of further new types of steel, including multi-phase types, at various points to promote effective energy management.
• Developing and improving energy paths by which the immense forces of frontal crash impacts are led through the structure and dissipated. Here, the engineers concentrated on optimizing the interaction between front-end deformation and the ability of the passenger space to remain intact. For severe frontal collisions – especially offset, when one side of the vehicle takes the brunt – they found ways to transfer the forces into the other side, so that the more heavily impacted side doesn’t have to absorb all the forces. The resulting extremely high energy-absorption capability is the basis for keeping the passenger space intact – and for optimum calibration of passive-safety systems such as safety belts and airbags.
• In side impacts as well, the structure is similarly designed to transfer impact energy to the side away from the impact. Here the IIHS’s “SUV test” raised the bar for occupant safety in severe side collisions. Elements that manage this massive impact energy include the –
• floor structure
• doors, which retain BMW’s effective interlocking door anchoring system
• reinforced B-pillars
• dash structure, which functions as much more than just a carrier for instruments, climate control, etc.
• roof framing.
• In rear-end impacts, the deformable area consists of –
• two longitudinal structural members
• the trunk floor and lid (Sedans) or tailgate (Sports Wagon)
• trunk or cargo-area side walls, as integral elements of the overall body-side structures
• various additional reinforcements.
Here, the engineers worked to ensure that even in the radically severe offset rear-end crash specified by FMVSS 301, the passenger space would remain intact, the doors could be opened and the fuel system would still be sealed.

The structure is virtually fully galvanized, enhancing corrosion resistance and thus helping preserve its strength and energy management over the years.

Front-to-rear Head Protection System. Now all BMW Sedans and Sports Wagons have this feature. Compared to the 5 and 7 Series’ inflatable-tubular/sail system, the 3 Series‘ curtain-type system takes up less space in the headliner – an advantage for the compact 3 Series. Like the tubular system, BMW’s curtain-type HPS can remain inflated for several seconds after initial deployment, an important function in case of rollover.

Automatic safety-belt tensioners and force limiters front and rear. Long standard on BMW front safety belts, these features now enhance the outboard rear belts’ effectiveness as well.

New occupant-detection sensor. BMW has long employed a sophisticated electronic control strategy for managing the deployment of airbags and safety-belt tensioners. This approach now becomes even more precise, thanks to a new sensing mat in the front passenger seat. Called OC3, the mat is more highly sophisticated than its predecessor; it measures the weight and analyzes the pressure distribution of the occupant in order to distinguish between an adult and an infant in a child safety seat.

New features for protecting the driver’s feet and knees. Two measures reduce the likelihood of injuries to the driver’s feet and legs:
• The footrest is designed to crush under the force of the driver’s left foot, so that the full impact force is not transmitted to his or her foot and leg.
• Brake and clutch pedals move forward under impact force, also reducing force transfer to the driver’s feet and legs if they are on the pedals.

Options: an expanded range offers
new and appealing choices
The program of factory options is notable not only for its extent and variety, but also because many features formerly available only on or in the “higher” 5, 6 and 7 Series now become available in this more accessible Series. Among these are a 6-speed automatic transmission, Active Steering, Active Cruise Control, Comfort Access, window sunshades for the rear and rear-door windows, Xenon Adaptive headlights, iDrive, Voice Command, the Logic7 audio system and factory-installed Sirius Satellite Radio. Features new to the 3 Series are denoted with an asterisk.

• Ski bag, for carrying skis and other long objects “indoors.”
The headlight cleaning system is standard on the AWD 325xi and 330xi models; split folding rear seats are standard in the 325xi Sports Wagon.

Stand-alone options:
6-speed* STEPTRONIC automatic transmission. Until now, 3 Series automatic transmissions have been 5-speed units.
Active Cruise Control*. Employing a radar sensor unit at the front of the vehicle, ACC senses the speed of vehicles traveling ahead, adjusts the BMW driver’s speed to maintain following distance, and offers the driver additional control choices over the standard (and new) Dynamic Cruise Control.
Active Steering*. Acting on the 3 Series‘ legendary rack-and-pinion steering, this system (available on 325i and 330i models) provides impressive benefits:
• Widely variable steering ratio; steering-wheel movements for parking maneuvers, U-turns and sharp corners are greatly reduced for amazing agility. With increasing vehicle speed, the steering ratio increases, favoring stability over agility.
• Vehicle stabilization; in critical situations, can intervene to preserve stability. For example, if the driver applies the brakes while driving on a surface with uneven traction (one side of the road slick, the other grippy), Active Steering can recognize incipient instability and steer against it.
Sport wheels and tires. The wheel and tire equipment of the RWD 325i/330i models is available, respectively, as a stand-alone option on AWD 325xi/330xi models equipped with their Sport Package.
Park Distance Control employs ultrasonic sensors in the rear bumper to detect obstacles that may not be visible to the driver, and emits an acoustic warning. When combined with the Navigation/iDrive option, PDC includes a vehicle diagram in the iDrive display*, which graphically depicts obstacles’ locations.
Xenon Adaptive* headlights with auto-leveling. Stronger, daylight-like illumination; headlights “steer” to enhance the driver’s view around curves and corners. Standard on 330i/xi, optional on 325i/xi models.
Comfort Access*. User enters vehicle merely by pulling a door handle; mere presence of the remote (say, in the user’s pocket or purse) confirms that entry is authorized. The driver starts the engine by pressing the Start/Stop button. Upon leaving the vehicle, merely pressing a door handle locks the vehicle.
Leather upholstery is available as a stand-alone option, in addition to being part of the Premium Package. New, more luxurious Dakota* leather.
Alternate interior trims at no extra cost: in place of the standard dark Burl Walnut*, buyers can choose lighter Poplar Natural* wood or aluminum trim with a brushed effect*.

Here, under the Condition-Based Service menu option, one can observe the remaining miles to selected service and maintenance procedures, as well as legally mandated inspections. (Examples: front and rear brake pads, brake fluid, sparkplugs, engine coolant.) Under TeleService, key vehicle data are transmitted automatically to the BMW center when the Condition-Based Service sensors detect an upcoming service need, or manually when the driver activates the Service Request button under BMW Assist in the control display. The BMW center then contacts the customer to set a service appointment. (Requires activated BMW Assist telematics.)
Sirius Satellite Radio. This appealing path to entertainment, news and information channels is available as a factory option. A subscription fee is required for Sirius service.
Logic7* sound system, with 13 premium speakers, Surround Sound, Digital Sound Processing; standard in 330i/xi, optional in 325i/xi models.
Power rear-window sunshade and manual rear door-window shades*, available for Sedans. The rear-window shade is controlled from a console switch; the side shades are easily raised or lowered by rear-seat passengers. Manual rear door-window shades are available for the Sports Wagon.

BMW Assist:
extra security and convenience
for the BMW owner
This comprehensive program of safety- and security-oriented customer services is available as part of the Premium Package, or as a stand-alone option.

The in-vehicle equipment for BMW Assist includes GPS technology and SOS/Assist functions in the front overhead console. Vehicle occupants may request emergency or other services simply by pressing a button; the BMW Assist system then transmits the location and vehicle information to the BMW Assist Response Center. A response specialist will then speak with the occupants to coordinate dispatch, notify emergency contacts on file, and link BMW Roadside Assistance or emergency services as needed and requested. Deployment of an airbag automatically activates BMW Assist as well.

A year’s subscription to BMW Assist Safety Services is included with the option; after the initial year, there is an annual fee. In addition to the safety-related benefits, subscribers to the BMW Assist Convenience Plan (available at extra cost) can call a toll-free 800 number to avail themselves of many BMW Assist Concierge services, from travel planning to dining reservations, shopping assistance and event tickets.
