The BMW F20/F21 is the second generation of the BMW 1 Series range of subcompact executive hatchback cars, which was released in 2011. The body styles of the F20/F21 range are a 3-door hatchback (model code F21) and a 5-door hatchback (model code F20).
The F20/F21 was initially powered by four-cylinder petrol, four-cylinder diesel and six-cylinder petrol engines. Unlike most hatchback competitors, the F20/F21 uses a longitudinally mounted engine and rear-wheel drive (instead of front-wheel drive) for most models. The F20/F21 is the first 1 Series to offer an optional all-wheel drive (called “xDrive” by BMW).
