BMW 3 Series (E90)

The sedan model was the first model sold of the E90/E91/E92/E93 3 series, being launched on 5 March 2005 for the 2006 model year.[19][20][21] Production continued until a facelift revision was made for the 2009 model year. Production of the E90 concluded after the 2011 model year, succeeded by the F30 for 2012.

The E91 wagon/estate models were marketed as 'Touring' in Europe and 'Sports Wagon' in North America.[22] Optional equipment included a panoramic sunroof, which extends to the rear passenger area. Trim levels typically were similar to the E90 saloon, however the M3 was not produced in the estate body style.[23]

Several markets outside Europe only offered a small subset of models in the estate body style. In the United States and Canada, the only estate model available prior to 2007 was the 325xi,[24] and then the 328i and 328xi from 2007 onwards. The Australian market received only a handful of models which included the 320i, 320d and 323i until the end of its production. No X-Drive models were ever sold in Australia of the E9x series. [25]

In July 2006, one year after the saloon was introduced, the E92 coupé body style was unveiled.

Compared with previous generations of the 3 Series, the coupé has more external styling differences to the saloon models. These include the tail-light design (L-shaped on the coupe), more steeply angled headlights and smaller side windows. As per its E46 predecessor, the doors of the coupe are longer and have frameless door windows, the rear seat holds two passengers (compared with a three-person bench for the saloon) with a rear centre console tray and the front seatbelts are on motorised arms that extend from the B-pillar to hand the seatbelts to the driver and/or passenger.

The E92 was the last generation to include coupé (and convertible) body styles as a part of the 3 Series range. For later generations, these body styles are marketed as the 4 Series. Despite the E90/E91 being phased out for the F30/F31 after the 2011 model year, the E92/E93 continued through the 2013 model year. It was then succeeded by the F32/F33 for the 2014 model year.

E93 with roof raised

The E93 convertible was BMW's first model to use a retractable hardtop (folding metal roof), instead of the cloth roof as previously used. The E93 was one of first retractable hardtops in its price range.[26][27] The "Comfort Access" option allows the roof to be raised and lowered using the key fob. The E93's side windows are 30 per cent larger than its E46 convertible predecessor, resulting in a 38 per cent increase in visibility.[28]

The BMW 3 Series convertible was often priced higher than direct rivals, however reviewers have praised its passenger/boot space (even with the roof down), driving dynamics, weight and chassis rigidity.[29][30][31][32]

Official specifications are as follows:[33]

Since the following generation of 3 Series used turbocharged engines for the entire model range, the E90/E91/E92/E93 was the last 3 Series to be available with naturally aspirated engines.

In North American, Australian and Malaysian markets the N53 was not used, Instead the entire model range continued to use its predecessor, the N52 engine.

In some areas of the United States, the 328i was powered by the BMW N51 straight-six engine and sold as a SULEV model.

In some parts of the world, 4-cylinder models continued to use the N46 engine as the local fuel quality is incompatible with the N43 engine.

To satisfy homologation requirements for the FIA World Touring Car Championship (WTCC), BMW built 2600 units of the 320si. The car featured N45 (N45B20S) engine producing 130 kW (174 bhp), 24bhp more than the regular 320i. It also featured revised suspension and 20% lower front bumper.[49]

BMW 335is (E93) with roof lowered

The 335is was produced in coupé and convertible models for the North American market. Its position in the model lineup was between the regular 335i and the M3, and approximately 4,500 units were produced. The 335is uses a higher performance version of the N54 engine, which increases boost from 8.7 to 11.6 psi (0.6 to 0.8 bar).[50] This results in 239 kW (320 bhp) and 450 N⋅m (332 lb⋅ft) of torque, plus an overboost function raises torque to 370 lb⋅ft (502 N⋅m) for up to 7 seconds.

Transmission options were a 7-speed double clutch transmission (DCT) with launch control or a 6-speed manual transmission. The manual transmission has an upgraded clutch compared to the regular 335i.

Other changes compared to the 335i include stiffer engine mounts, a higher-flow exhaust system, an upgraded cooling system, a different steering wheel, sport seats and "335is" badging on dash and in the instrument cluster.[51][52] Exterior differences are larger air openings in the front bumper, a rear bumper that incorporates a diffuser-style piece, black kidney grills, and 18-inch or 19-inch "Style 313" wheels.

In September 2008, the facelift (LCI) versions of the saloon and estate were released for the 2009 model year. Compared to typically subtle BMW LCI changes, these changes were relatively extensive.

Mechanical changes included an increase in rear track of 24 mm (0.94 in) for some models, a power increase for the 320d from 130 to 135 kW (174 to 181 bhp) and the N57 engine replacing the M57 for the 330d model.

Styling changes included front and rear bumpers, wing mirrors, headlights, taillights, boot lid, wider kidney grilles and revised crease lines for the bonnet.[53][54] The new 2009 – 2011 facelift (LCI) AWD models became known as "xDrive" models, unlike the previous 2006–2008 (pre-lci) AWD models, which were labeled as "xi" models. The new xDrive models received xDrive badges on the bumper and both the right and left sides right below the side marker lamps. For the interior, crash-activated head restraints were added to the front seats, the optional "Professional" navigation system was updated, iDrive was updated and the resolution of the display was increased.

For the 2010 model year,[55] the Sport, Lifestyle and Exclusive Edition were introduced for saloon and estate models. The 316d estate model was added, as was the 320d EfficientDynamics Edition saloon.

Mechanical changes included compliance with the EU5 emission standard, EU6 emission compliance (optional) for the 320d and 330d models, power increases for the 318d, 320d, 325d and 330d models, the N54 engine in the 335i being replaced by N55 engine, and additional features for BMW ConnectedDrive.

The Insurance Institute for Highway Safety (IIHS) gives the 3 Series a "Good" overall rating in both the frontal and side impact crash tests. The 3 Series received "Good" marks in all six of the frontal crash test categories,[57] and "Good" marks in six of the nine categories in the side impact test.[58] The IIHS also gave the 3 Series the Top Safety Pick award. The convertible is rated "Marginal" in side impacts,[59] making the 3 Series convertible the lowest rated vehicle currently sold in its class in IIHS tests.[60]
