Alpina B6 Biturbo faster than M6 F13 - 208mph top speed [video]

Sport Auto test drive editor Christian Gebhardt has sent us his latest video for the 2013 Alpina B6 Biturbo. Here we see Gebhardt perform his usual statics shots followed by a high-speed performance test with a fixed camera shot of the instrument cluster.

Starting from stand still, the B6 hits a top speed of 208 mph (334 km/h) according to the speedometer, however, Gebhardt tells us his GPS unit logged 204 mph (328 km/h). This top speed is significantly higher than the standard BMW M6 equipped with a M Driver's Package which tops at 189 mph (305 km/h), and is also higher than Alpina's own specification of 199 mph (320 km/h).

Mechanically, the Alpina B6 Biturbo differs from the M6 with a rebuilt 4.4-liter twin-turbo V8 engine using Mahle pistons, a high-performance cooling system, a revised eight-speed automatic transmission and a titanium exhaust system from Akrapovic. The B6 Biturbo Coupe ironically develops less power with 533 hp (397 kW / 540 PS) but more torque of 516 lb-ft (700 Nm) compared to the M6 with 552 hp (412 kW / 560 PS) and 502 lb-ft (680 Nm). The B6 Biturbo runs 0 to 62 mph (100 km/h) in 4.4 seconds while the M6 in 4.2 seconds.
