The Alpina B6 Bi-Turbo Coupé, revealed at Tokyo motor show today, is the German firm’s variant of the BMW 6-series.
The 4.4-litre V8 in the B6 Bi-Turbo Coupé produces 533bhp and 516lb ft and helps the car to crack 0-62mph in 4.4sec. The top speed is a claimed 197mph.
Two turbochargers configured in parallel, each feeding one of the two cylinder banks, allow the engine to provide plenty of power and torque over a broad rpm range.
The B6 gets an eight-speed sport automatic gearbox developed in conjunction with transmission specialist ZF. It also features a limited-slip rear differential.
Alpina has collaborated with Akrapovic on a lightweight titanium exhaust system for the B6. The unit is half the weight of a stainless steel version.
The B6 Bi-Turbo Coupé comes with electronically adjustable dampers and active roll stabilisation as standard. A choice of four driving modes – Comfort+, Comfort, Sport and Sport+ – can be selected.
Cosmetic changes include a front spoiler with an integrated carbonfibre splitter that reduces the air masses under the car by more than ten per cent, making the front-end more stable and reducing understeer. The rear spoiler is replaced by a more dramatic wing.
The B6 Cabriolet, first seen at Frankfurt in the autumn with 500bhp, has also been given the upgraded 533bhp engine. The car will go on sale in January, with the coupe priced from £92,950 and the cabrio from £97,950.
