4.4 liter twin-turbo V8 now develops an output of 540 PS (397 kW / 533 hp) and 700 Nm (516 lb-ft) of torque.
German automaker BMW Alpina has unveiled the 2012 B6 Bi-Turbo Coupe.
The B6 Bi-Turbo Coupe features the aluminum twin-turbo 4.4-liter V8, equipped with MAHLE pistons and a high-performance cooling system, which now develops an output of 540 PS (397 kW / 533 hp) and 700 Nm (516 lb-ft) of torque. That's 33 more horsepower than on the recently announced B6 Bi-Turbo Cabriolet.
With the help of a revised eight-speed automatic transmission and a titanium exhaust system from Akrapovic, the 0 to 100km/h sprint takes just 4.4 seconds and top speed is 320 km/h.
The B6 Bi-Turbo Coupe also comes with an aerodynamic kit that includes a front spoiler with the integrated carbon fiber front splitter and a rear spoiler with an optional rear wing.
For the suspension, the B6 Bi-Turbo features Drive Performance Control (electronically adjustable dampers) and Dynamic Drive (active roll stabilization) as standard.
Wheels are the 20-inch Alpina Classic rims fitted with Michelin Pilot Super Sport tires.
For the interior the car gets a sport steering wheel hand-stitched in Lavalina leather, blue illuminated entry sills with logo and a trim in the classic Alpina myrtle wood.
