BMW 6 Series (F12)
The third generation of the BMW 6 Series consists of the BMW F12 (two-door convertible version), BMW F13 (two-door coupé version) BMW F06 (four-door "Gran Coupé" version) executive-sized grand tourers. The F12/F13/F06 generation was produced from 2011 to 2018 and is often collectively referred to as the F12. The F12 shares a platform and many features with the F10 5 Series and F01 7 Series, with the two-door F12/13 models having a shorter wheelbase than the F10, while the four-door F06's wheelbase matches the F10's. The M6 version is powered by the S63 twin-turbocharged V8 engine mated to a 7-speed dual clutch transmission. It is the first M6 model to use a turbocharged engine. Production of the F12 generation ended when the Gran Coupe models were discontinued in September 2018. The successor to the F12, the BMW 8 Series (G15), began production in June 2018.
