Two turbochargers configured in parallel, each feeding one of the two cylinder banks, with specially developed large diameter exhaust-turbines allow this engine configuration push you forward. The engine is linked to an adapted Switch-Tronic eight-speed Sport Automatic Transmission. The setup was tested in co-operation with ZF.
The Alpina B6 Bi-Turbo does a sprint from 0 to 100km/h in 4.4s and a top speed of 320km/h.
Besides the increase in power, the Alpina B6 BiTurbo Coupe received some aerodynamics enhancements such as a front spoiler with the integrated carbon fiber front splitter and a rear spoiler with an optional rear wing.
