As was expected, Alpina is hard at work producing their variant of the all new BMW 4 Series coupe, as new spy shots indicate.

With the 4 Series available for purchase in a few weeks, the guys from Alpina do their best to make the B4 F32 BMW ready to launch by March, 2014.

Alpina’s B4 caught on camera is still in early development as the body work is yet to receive the special treatment we can expect from the tuner. But the traditional multi-spoke large wheels, the blue brake calipers and the quad exhaust tips gave it away.

These spy shots would represent the first appearance of the Alpina B4 Bi-Turbo Coupe, and between now and the expected official unveiling at the next Geneva Auto Show, we should see the car evolve into the machines to which Alpina accustomed its buyers.
