The BMW N63 is a twin-turbocharged petrol V8 engine which has been in production from 2008 to present. The N63 is the world's first production car engine to use a "hot-vee" layout, with the turbochargers located inside the "V" of the engine. It is also BMW's first turbocharged petrol V8 engine. The engine has been widely noted for its mechanical issues, undergoing several recalls.[1][2][3][4][5][6]

The N63 replaced the BMW N62 (a naturally aspirated V8 engine) and was first used in the 2008 X6 xDrive50i.[7]

The S63 engine is the BMW M high-performance version of the N63.

Alpina versions of the N63 are used in various F01 7 Series, F10 5 Series, G11 7 Series, G15 8 Series and G30 5 Series models.
