BMW 3 Series gearboxes through the ages

While the 3 Series, which began with the E21, entered automotive history as a rather compact sedan model, subsequent generations soon became synonymous with sportiness andelegance. Whether sedan, coupé or station wagon, the BMW 3 Series now comes in a wide variety of models.

BMW 3 Series: 1st generation (1975-1983)

Designed by Paul Bracq, the BMW E21 went down in automotive history as a rather compact, safe-driving sedan that immediately won over drivers. This model was equipped with a 5-speed gearbox.

BMW 3 Series: 2nd generation (1982-1994)

Now featuring twin headlamps, four doors and a Cabriolet version, the BMW E30 is available with manual or automatic gearboxes with 3, 4 or 5 speeds, depending on the model.

BMW 3 Series: 3rd generation (1990-2000)

More comfortable, but also more agile in its driving style, the BMW E36 features a manual or automatic gearbox with 3, 4, 5 or 6 speeds, depending on the model.

BMW 3 Series: 4th generation (1998-2007)

Available in Coupé, Cabriolet or Compact versions, the BMW E46, still in the sporting vein of previous models, offers greater safety while reducing fuel consumption. The gearbox is available as a 5- or 6-speed manual, or as a 4-, 5- or 6-speed automatic.

BMW 3 Series: 5th generation (2005-2013)

Named "World Car of the Year", the fifth generation of the 3 Series continues the success story. Available in several versions (Sedan, Touring, Coupé, Cabriolet), it features a 6-speed manual or automatic gearbox, depending on the model.

BMW 3 Series: 6th generation (2011-2019)

With this new generation, the German manufacturer is injecting a new dose of technology into the 3 Series, while at the same time overhauling its design lines: this includes the arrival of hybrid-powered engines in the range. Gearboxes are either 6-speed manual or 8-speed automatic.

BMW 3 Series: 7th generation (since 2019)

More aerodynamic than previous versions and featuring new assistance systems, the seventh generation now offers a semi-autonomous driving experience. The gearbox is now exclusively automatic, with 8 speeds.

Steptronic gearbox: present on all the latest vehicle models.

All the latest Series 3 models are equipped with either :

• automatic gearbox;
• a Steptronic gearbox with steering-wheel-mounted paddles for automatic or manual gear changes, depending on the selected mode;
• a Steptronic sports gearbox, allowing you to opt for sportier ratios.
