With a top speed of 306 km/h, the new BMW ALPINA B4 S is not only one of the fastest in its class, but also one of the fastest at the 2017 Geneva Motor Show. At the official world debut in Geneva, the refreshing ALPINA B4 Coupe is a little bit in the shadow of the brand new B5, but thanks to the facelift optics adopted by the BMW 4 Series, the B4 is even more fresh. Special attention has been paid to the headlights and taillights, because here a completely new interior life ensures a considerably more modern and even more self-assured look.

A car like the BMW ALPINA B4 S can, of course, also afford this self-assurance, as on a dry ground the sprint from 0 to 100 – with the optional all-wheel drive – succeeds in just 3.9 seconds. The double speed is not reached until 10 seconds later – and the lighter rear-wheel drive, which can be seen in Geneva for the new B4 family, is barely slower with 4.2 and 13.6 seconds from the stand. At the top speed, the B4 S ultimately benefits from the less complex drivetrain, which also works with less friction losses.

Just like before the facelift, a BMW series six-seater cylinder of the generation N55, profoundly modified in Buchloe, is responsible for the performance and sound of the M4 rival. The maximum torque increase of 660 Newton meters is available between 3,000 and 4,500 RPM and promises extreme sovereignty in every living situation. Incidentally: the rated power of 440 hp is not only at a certain speed, but also in a relatively wide speed range between 5,500 and 6,250 rpm.

The prices for the new BMW ALPINA B4 S start at 75,300 euros for the rear-mounted Coupé. If it is the B4 S all-wheel drive, at least 78,200 euros are due. The most expensive member of the new B4 family, however, is the B4 S Cabrio, which is exclusively available with rear-wheel drive and is sold at prices starting at 81,400 euros.
