The BMW 1 Series (F40) is the third generation of the BMW 1 Series range of subcompact executive hatchback cars. Unlike the previous generation F20 1 Series, the F40 1 Series uses a front-wheel drive configuration and is only available as a 5-door hatchback.

The vehicle started off using the Evo ID5/ID6 system, then in 2021 changed over to MGU ID7.
