BMW E90

The fifth generation of the BMW 3 Series range of compact executive cars is designated under the model codes E90 (saloon), E91 (estate, marketed as 'Touring'), E92 (coupé) and E93 (convertible). The model was introduced in December 2004, and produced by BMW until October 2013 and is often collectively referred to as the E90, E9x, or occasionally, the E92.

The E92 335i was the first 3 Series model produced with a turbocharged petrol engine. It was also the first 3 Series to include the iDrive operating system, which consists of navigation, infotainment and essential vehicle functions. The E9x saw the introduction of run-flat tyres to the 3 Series range. Models with run-flat tires are not equipped with a spare tyre.

The E90/E92/E93 M3 is the only generation of M3 to be powered by a V8 engine. Introduced in 2007, it uses the BMW S65 naturally aspirated V8 engine and was produced in saloon, coupé and convertible body styles.

Following the introduction of the F30/F31 3 Series in February 2012, the E90/E91 saloons and estates were phased out. However due to their later introduction, the E92/E93 coupés and convertibles remained in production through the 2013 model year, after which they were replaced by the F32/F33 4 Series models.

Development and launch

The design for the fifth generation 3 Series was frozen in mid-2002, approximately 30 months before the start of production. The saloon and estate were designed by Joji Nagashima. Marc Michael Markefka designed the coupé and convertible.

The range was introduced in March 2005 for MY2005 with the saloon and estate body styles. The coupé was introduced in 2006 and the convertible was introduced in 2007, both for MY2007.

Significant cosmetic and mechanical changes were done to improve the design and performance compared to the previous generation. The E90 series is larger than its predecessor, with a longer wheelbase, wider tracks, and a roomier interior.

Sedan (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. 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.

Touring (E91)

The E91 wagon/estate models were marketed as 'Touring' in Europe and 'Sports Wagon' in North America. 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.

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, 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.

Coupé (E92)

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.

Convertible (E93)

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. 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.

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.

Engines

Petrol

Official specifications are as follows:

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.

Special Editions

Model year changes

2008 Facelift (LCI)

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 for some models 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. 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" or "xd" 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.

Safety

The Euro NCAP noted the poor pedestrian protection awarding 4 points out of 36, reporting the 3 Series was "very disappointing" in this measure.

IIHS

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, and "Good" marks in six of the nine categories in the side impact test. The IIHS also gave the 3 Series the ''Top Safety Pick'' award. The convertible is rated "Marginal" in side impacts, making the 3 Series convertible the lowest rated vehicle currently sold in its class in IIHS tests.

Recalls

In November 2017, BMW recalled 672,000 3 Series cars from model years 2006–11 with climate control system electronic components at risk of overheating, due to faulty blower motor wiring.
