Why it matters

The B7 S Turbo was Alpina's turbocharged super-saloon based on the E12 535i, the fastest 5 Series of its day. Only 60 were built in the E12's last two years.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Alpina's first B7 Turbo arrived in 1978 on the 528i, raising its 2.8-litre six from 173 to 295 hp. For 1981 the company moved to the new 535i, turned up the boost and fitted a new ignition system, adding an 'S' to the name. Production was confined to 1981 and 1982, the E12's final model year.
