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.
