BMW N73
Reciprocating internal combustion engine
The BMW N73 is a naturally aspirated V12 petrol engine which replaced the BMW M73 and was produced from 2003–2016. It was used in the BMW 7 Series and Rolls-Royce Phantom.
The N73 was the world's first production V12 engine to use gasoline direct injection.[1]
Compared with its M73 predecessor, the N73 has dual overhead camshafts, double-VANOS (variable valve timing) and valvetronic (variable valve lift).[2][3]
