Remember the two Geneva-debuting Alpina BMWs we showed you earlier in the month? In these videos company owner and sales and marketing head Andreas Bovensiepens talks about the philosophy and engineering behind the XD3 Biturbo and B3 Biturbo models. There’s some snow action to be seen as well.

The Alpina XD3 Biturbo is the company’s first SUV, based on the BMW X3, in xDrive35d guise. Its 3.0 litre twin-turbo diesel engine has been tuned to produce 350 PS and 700 Nm of twist, propelling the vehicle to 100 km/h from a standstill in a smidgen under five seconds and onwards to a top whack of 253 km/h.

The Alpina B3 Biturbo however, is based on the BMW F30 335i, only its 3.0 litre twin-turbo six-cylinder petrol lump has been boosted to 410 PS and 600 Nm of peak torque (with RON 98 fuel). An estate version can be seen in this video.

RWD and xDrive versions are available for the B3 Biturbo, with the former doing the century sprint in 4.2 seconds and the latter doing it in four seconds flat. Top speed is in excess of 300 km/h.
