History of the Alpina Roadster S
The Roadster S was the third open sports car presented by Alpina, after the Z1 RLE (Roadster Limited Edition) and the V8 Roadster unveiled in 2001. Based on the Z4 3.0i, it was available in two trims: standard and Luxury. An optional Sport pack added a thicker anti-roll bar.
The engine is a hand-built 3.4-litre E5/2 straight-six also shared with the B3 S (E46), an enlarged version of the S52B32 first installed in the North American M3 (E36). Unusually for a modern Alpina, the Roadster S dispensed with the Switch-Tronic automatic transmission and has a close-ratio six-speed manual built by ZF.
