A publication based overseas has released a video clip that appears to be a night-time run in an Alpina B6 Biturbo.
Now what's interesting here is that the B6 only has 540 horsepower but, clearly, the more important figure here is torque as the B6 seen here is actually faster than BMW's own effort in the all-new M6.
However, I still think I'd rather have the M6. Alpina's kits usually are far too old-school for my taste...
Sport Auto has released a top speed run video of the Alpina B6 Biturbo, powered by BMW's 4.4L V8 engine rated at 540hp and 730nm torque and top speed of 334 km/h. For comparison, the new F12/F13 M6 features 560hp and 680Nm torque with a top speed of 305 km/h.
