Alpina B4 Specs, Engines & Dimensions (2012–2017) — First Generation
The first-generation Alpina B4 takes the compact BMW coupe and convertible formula in a distinctly relaxed direction: strong mid-range pull, long-legged cruising and hand-finished detail, offered in Coupe and open-top Cabrio form.
Every Alpina B4 engine here is a turbocharged 3.0-litre petrol six, tuned for effortless torque rather than a high-revving peak. The automatic transmission suits that character, shifting smoothly in traffic and holding gears when pressed. Examples include rear-wheel-drive Cabrio and Coupe versions, plus a Coupe with all-wheel drive for extra traction.
