Sport Auto’s Christian Gebhardt gets behind the wheel of the rare Alpina B3 GT3, based on BMW 335i, and as usual he does a 0 to top speed test. That is the best way to judge a car’s performance the way everyone understand it. It’s a test of both acceleration and top speed, and it’s especially impressive in the case of the the B3, because after all, it’s a 3er that can do 309 km/h. The B3 GT3 is limited to 99 units.

The exceptionally smooth twin turbocharged 3.0liter in line six-cylinder engine from the Alpina B3 S Bi-Turbo – with its massive torque and effortless performance – is also employed in the B3 GT3. By amending the exhaust system and replacing the rear silencer the back pressure has been further reduced, increasing output in the B3 GT3 by 8hp. The direct petrol injected engine now delivers a total power output of 408hp at 6000rpm and 540Nm of torque at 4500rpm.
