The second generation BMW 1 Series range comprises three-door hatchback (model code F21) and five-door hatchback (F20) models. Like its E87 predecessor, it uses a longitudinally-mounted engine, aluminum multi-link suspension and a rear-wheel drive chassis (however some models are available with all-wheel drive).
Transmission options are a six-speed manual or an eight-speed ZF 8HP automatic.
