Famous BMW tuner Alpina has been caught testing its upcoming B4 model on the track.

The B4, which will be based on the BMW 4-Series coupe, features the same bi-turbo engine found under the hood of the B3 sedan, which was unveiled at this year’s Geneva Motor Show. The B3 Bi-Turbo features a 3.0-liter, twin-turbo straight-six engine with 410 hp and 442 lb-ft of torque.

The Alpina B4 will also get the standard treatment all Alpina models get, including an aerodynamic body kit, wheels and suspension. There might also be a chance that the B4 will offer an all-wheel-drive variant.

The Alpina B4 is expected to make its debut at the 2014 Geneva Motor Show.

good question, my guess is that they are going off of some what i believe to be leaked engine specs. i think a while back some of the engines and engine specs were leaked

Alpina never lets us down. That is an incredible amount of power. I wonder if that is where the power band maxes out.
