Alpina to launch the B4 S Bi-turbo at the London Motor Show 2017

Luxury vehicle manufacturer Alpina will launch its new B4 S Bi-turbo at the 2017 London Motor Show, following the model's international preview at the Geneva Motor Show in March. The new B4 S Bi-turbo - available as a coupe and convertible - provides a unique combination of comfort, refinement and high-performance that is a hallmark of Alpina's extensive engineering development. The manufacturer is famed for developing high-performance versions of BMWs, and its new model doesn't disappoint.

With two new Alpina-specific turbochargers and an uprated cooling system, power climbs from the previous model's 410bhp to 434bhp and torque leaps from 600Nm to 660Nm, giving the luxury four-seater a top speed of 306km/h and acceleration that will take it from 0-100km/h in just 3.9 seconds.

Based on BMW's latest generation 4 Series, the B4 S Bi-turbo is the result of a two-year development programme during which every aspect of the vehicle was analysed and refined to increase performance, comfort, efficiency and style; compared with the standard 4 Series. Alpina's newest creation will take to the Battersea Evolution, Battersea Park in the U.K. from 4^th to 7^th May and, just like in Geneva, is sure to cause something of a stir with visitors.
