2014 Alpina B4 BiTurbo spied on the track image

The brand new Alpina B4 BiTurbo has been recently spied on the track, where the tuner’s drivers were testing the model before pulling the wraps off its body.

The new generation of the BMW 4-Series may have been unveiled recently by the German based automaker but that doesn’t mean that tuners can’t get a go with the new model. The first and probably most important car tuner to modify the new BMW 4-Series Coupe is named Alpina, and the model in question has been recently caught on camera, by our spy photographers, while it was being tested on the track.

In the images posted below we can already see the Alpina treatment applied to the new BMW 4-Series Coupe, starting with the rims, going to the front bumper, rear diffuser, rear spoiler and the dual exhaust setup. The model in question is actually a prototype but the final version is believed to get the same treatment, along with some changes in the cabin, like the multi spoke steering wheel and much more. The 3.0 liter straight six-cylinder engine from the 435i Coupe is believed to get 410 HP and 442 lb-ft of torque, from the standard 300 HP and 300 lb-ft of torque. This will allow the B4 BiTurbo to sprint from 0 to 60 mph in 4.0 seconds and to reach a top speed of 190 mph.
