The BMW N74 is a twin-turbocharged V12 DOHC piston engine which replaced the N73 and was produced from 2009-present (as of November 2013).

Design[edit]

Compared with its N73 naturally-aspirated predecessor, the N74 features twin-turbochargers. The N74 was the first turbocharged BMW engine to feature variable valve lift and variable valve timing.[citation needed]

The engine marked BMW's first use of an 8-speed automatic transmission (the ZF 8HP90).[1]
