Spyshots: 2014 Alpina B4 Biturbo Coupe (F32 BMW 4 Series)
Here's Alpina's latest baby, the B4 Coupe, a Biturbo model that's based on the brand new 4 Series. When ready, this 435i derivative will come close to matching the new M4, if not surpassing it, while also offering a distinct brand of luxury.
Alpina already sells a B3 Biturbo sedan, which will be a sort of mechanical blueprint. But the 4 Series is a sportier car than the 3 Series, thus meaning the B4 will be that little bit more special.
As for the powerplant, the B4 will have a twin-turbo 3-liter engine capable of delivering 410 hp and 600 Nm of torque. 0 to 100 km/h will go by in about 4 seconds. The cool thing is, unlike the M3, you'll be able to buy it with xDrive as well.
