ALPINA B7S TURBO(e-12)

The B7 Turbo was the fastest 4-door car in the world until Alpina introduced this car, the B7S Turbo. The B7S was a limited-edition series, only 60 cars were built between November 1981 and May 1982. So if you have one of these, keep it.

Engine/Gearbox

This time Alpina used BMW´s 3,5 litre engine instead of the 3,0 litre unit as in the "ordinary" B7 Turbo. Alpina have made the same changes to the 3,5 litre engine as to the 3,0 litre. But there are some differences. The KKK K27 turbocharger now has a maximum boost of 0,9 bar. A new ignition-system is fitted made by AFT. The B7S produces 330 bhp and has a maximum torque of 500 Nm, the same as in the new BMW M5. The Getrag gearbox is replaced by a ZF five-speeder, which they had developed for the BMW 745i.

Suspension/Brakes/Wheels

The B7S have Bilstein gas-pressure spring units and progressive springs at front and Bilstein gas-pressure shocks and height-adjustable progressive springs at rear. It also have adjustable stabilizers at both front and rear. The brakes are the same as in the B7 Turbo with ventilated discs all-around. The alloys are 16in high with 205/55 tires at front and 225/50 at rear.

Interior/Exterior

Inside, the B7S have all the features a B7 have plus some more like black sunvisors and ceiling. From outside, the B7S is distinguished by their beautiful blue colour which is called "Dunkelsaphirblau metallic" with Alpina deco-set in gold. Other changes are black door-handles and B-post.

Performance

Look out BMW M-, Mercedes AMG- and Porsche owners. Alpina claims a 0-100 km/h time of 5,9 seconds and a top speed of 260 km/h. But according to Auto Motor und Sport the B7S accelerates from 0-100 km/h in 5,8 seconds, 0-160 km/h in 12,5 seconds, 0-200 km/h in 20,3 seconds and have a top speed of 261 km/h.
