Alpina is filling the void between regular 5-series and upcoming M5 with its new B5 Bi-Turbo.

Revealed at the 2017 Geneva Motor Show, the new B5 is Alpina's fastest-accelerating vehicle yet. All it takes is 3.5 seconds to reach 100 km/h from a standstill.


Keep the throttle pegged to the floor and you'll pass 200 km/h in 11.4 seconds, eventually topping out at 328 km/h. Just the ticket for a high-speed romp down a derestricted stretch of the Autobahn. And Alpina pulled every trick in the book to make sure it would be.

The 4.4-liter twin-turbo V8 kicks out 600 horsepower and 590 lb-ft of torque. That's slightly more power but significantly more torque than the 30 Jahre edition that was the most potent M5 to date.


The new B5 also features all-wheel drive, four-wheel steering, and an eight-speed automatic transmission with Connected Shift technology to anticipate the required gear based on GPS data.

Perhaps best of all is that while the M5 has traditionally been a sedan-only affair, the B5 is offered as a wagon as well. Prices in Germany (including 19% tax) start at € 112,000 – or € 7,700 more than BMW charged locally for the outgoing M5 before the order books closed. Deliveries kick off in September.
