Product Overview

Alpina Roadster S E85 is a subcompact convertible based on the E85 Z4 3.0i in production from 2003 to 2006. It was powered by a bored-out S52B32 naturally-aspirated inline-6 engine that displaced 3.3 liters also found in the E46 B3 S.
As usual, the Roadster S received the standard Alpina treatment with body kit. However, its wheel design is quite different than the usual Alpina classic multi-spoke. Further, Alpina used a 6-speed manual transmission, whereas most of its vehicles use automatics.
These unique points, combined with the models low sales, make the Roadster S an interesting collector's car.
