In 2014, BMW introduced their new line of cars, the 4 Series. The 4 Series was spawned from the BMW 3 Series 2-door coupes. Initially available as a coupe or convertible, a 4-door fastback named the 4 Series Gran Coupe was added for 2015. Although the first generation is collectively known as the F32, each body style has its own designator: the F32 Coupe, the F33 Convertible, and the F36 Gran Coupe. All 4 Series cars were offered with a variety of turbocharged inline 4 or inline 6 engines. BMW introduced the second generation G22 for the 2021 model year.
