Alpina has introduced the B6 Bi-Turbo Convertible at the Frankfurt Motor Show.
Based on the BMW 650i, the B6 has an aerodynamic body kit, a four-tailpipe Akrapovic exhaust system and 20-inch alloy wheels with Michelin Pilot Super Sport tires.
To spruce up the cabin, designers added a revised instrument cluster, a sport steering wheel, burl wood trim and illuminated door sill plates.
The twin-turbo 4.4-liter V8 has been equipped with MAHLE pistons and a high-performance cooling system. Thanks to these tweaks, the engine develops 507 PS (373 kW / 500 hp) and 700 Nm (516 lb-ft) of torque - an increase of 100 PS (74 kW / 99 hp) and 100 Nm (74 lb-ft). It is connected to a revised eight-speed automatic transmission which enables the car to accelerate from 0-100 km/h in 4.8 seconds and hit a top speed of 311 km/h (193 mph). In terms of efficiency, the convertible averages 10.9 L/100km (25.9 mpg UK / 21.5 mpg US) and emits 255 g/km.
