The second generation of the BMW 1 Series consists of the BMW F20 (5-door hatchback) and BMW F21 (3-door hatchback) subcompact cars. The F20/F21 generation was produced by BMW from 2011 to 2019 and is often collectively referred to as the F20.

For the second generation of 1 Series, the coupé and convertible models marketed separately using the new BMW 2 Series nameplate.

El F20/F21 contaba inicialmente con motores de gasolina de cuatro cilindros en línea, diésel de cuatro cilindros en línea y gasolina de seis cilindros en línea. En 2015, se añadieron a la gama motores de gasolina y diésel de tres cilindros en línea. Todos los motores son turboalimentados.

Unlike most hatchback competitors, the F20/F21 uses a rear-wheel drive (rather than 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).

In July 2019, the BMW 1 Series (F40) began production as the successor to the F20.
