BMW 1 Series

The BMW 1 Series is a line of small family cars manufactured by the German automaker BMW since 2004. Successor to the BMW Compact, it has been produced in four different body styles.

The 1 Series was launched globally in Autumn 2004 and shares many structural, chassis, powertrain, hardware and electronic elements with the larger 3 Series. The model was started to provide a lower point of entry into the BMW range as the 3 Series moved gradually up-market. Initially launched as a 5-door hatchback, a 2-door coupe version was also launched in July 2007. The 1 Series is priced between the MINI and the current E90 3 Series. Because the hatchback is the only rear wheel drive vehicle in its class, it is often considered the successor to the BMW 2002. The 1 Series line is produced in Leipzig, Germany at BMW's factory.

The 1 Series coupe (E82) and convertible (E88) went on sale in the United States and Canada in model year 2008 (30 June 2007)^[1] as the 128i and the 135i. Other countries received the 120i and 125i in both platforms. The convertible, unlike the 3 Series convertible, uses a soft-top instead of a folding hardtop. This is lighter and preserves more boot space than the folding hardtop would allow.
The North American introduction of the coupe and cabriolet was during the second quarter of 2008, which was credited for helping BMW overtake Lexus as the top luxury brand.

The next full revision of the 1 Series is expected on sale for the 2012 model year based on the platform F20. The 5 door was unveiled by BMW on 6 June 2011, powered by a new 1.6 petrol and revamped 2.0 diesel engines, both featuring twin-turbos ^[5] Three-door, coupé and convertible versions will follow in due course. There is also expected to be a special hatchback version with a coupé-like style similar to the 5 Series Gran Turismo, and this will slot above the regular 1 Series hatchbacks. The new F20 platform also has support for a front wheel drive layout and this will underpin the next Mini and as-yet undisclosed BMW model to slot in below the 1 series.
