The technology driven Germans working at Aplina have finished their working on the new B6 BiTurbo Coupe based on the 2012 BMW 6 Series.
The car uses an all-aluminium V8 with two parallel turbochargers, specially developed exhaust turbines, a high performance cooling system plus a titanium exhaust system from Akrapovic, and as a result it now delivers 540 HP (397 kW) at 5,500 rpm anf 700 Nm of torque from 3,000 rpm.
Much of the power increase has also resulted from the high-performance MAHLE pistons designed to deal with increased temperatures and pressures plus the direct injection system and the Double-VANOS technology which helps the Alpina B6 BiTurbo Coupe maintain class leading consumption and emission figures of 10.5 (10.6) litres per 100 Km and 244 (247) grammes of CO2 per Km.
The car’s transmission which is an SWITCH-TRONIC 8-speed Sport Automatic, adapted and tested in collaboration with ZF is also a key component in this car, as it enables the Alpina B6 BiTurbo Coupe to sprint from 0 to 100 Km/h in 4.4 seconds a reach a maximum speed of 320 Km/h.
Apart from being fitted with an aero kit, the new Alpina B6 BiTurbo has also received the automaker’s 20-inch multispoke design wheels, a set of electronically adjustable dampers and active roll stabilisation through the Dynamic Drive system. 
Massive breaks and a full interior treatment are also part of the deal, and even though we don’t know the pricing on this thing, cosndering the extensive list of enhancements it is safe to assume that it won’t be cheap.
