Alpina’s new B7 Biturbo is capable of doing 205mph, thanks to the power gains produced by its heavily reworked V8 engine.
Peak output of the car’s 4.4-litre twin-turbocharged unit is 600bhp and 590lb ft (156bhp and 111lb ft more than the 750i), helped by an increase in boost pressure from 1.0 to 1.2 bar, which is fed by a wider-bore intake system.
Alpina has also fitted a new direct intercooler system to improve the engine’s temperature management, something the firm claims enables it to handle high loads for long periods of time.
The car’s eight-speed ZF gearbox, which can be controlled manually via buttons on the back of the steering wheel, has also been retuned, with additional cooling, strengthened gear clusters and a larger torque converter.
UK cars come exclusively in rear-wheel drive and with a long wheelbase body, but even in this heavier form are capable of accelerating from 0-62mph in 4.0sec.
