The Alpina B8 is a BMW-based Alpina that has existed in two eras: the E36-based B8 4.6 of the 1990s, which used the enlarged 4.6-litre V8 also fitted to the B10 4.6, and the B8 Gran Coupé of 2021, based on the BMW M850i with a 630 PS twin-turbo V8.

History of the Alpina B8

In the 1990s Alpina fitted a re-designed and enlarged 4.6-litre V8 to the E36 Alpina B8 4.6 and to the E34 B10 4.6, which replaced the B10 Bi-Turbo from March 1994. With 250 kW (340 PS) the V8 was only just below the output of the B10 Bi-Turbo.
