BMW N55
The BMW N55 is a turbocharged direct injection straight-6 DOHC engine which began production in 2009 and presently (2015) remains in production. It was launched in the F01 535i Gran Turismo. The N55 began to be phased out following the introduction of the B58 engine in 2015.
Compared with its N54 predecessor, the N55 features a single twin-scroll turbo (the N54 uses twin turbos) and variable valve lift (called Valvetronic by BMW).
The F80 M3 and F82 M4 are powered by the S55 engine, which is the high performance version of the N55.
