History

This ALPINA edition of BMWs contemporary classic roadster. A Z8 with an automatic transmission A new ZE powered not by the BMW M engine, butrather by a specially developed, higher-performance version of BMWs regular V-8 engine A new Z8 with 20-inch wheels and tires in place of the original 18-inch.

The Alpina version based on the Z8 appeared in mid-2002 . The difference with the BMW Z8 is mainly due to a stronger torque V8 engine with a maximum output of 280 kW (381 hp)  and an automatic transmission , to make it more interesting for the American and Japanese market. Like the Z8, this vehicle was sold in the USA by BMW AG.
