Caught! BMW M4 testing

BMW’s new M4 has been caught testing at the Nurburgring, with these images giving us the best look yet at the new performance coupe.

The images clearly show how the new model, which is to be revealed later this year, is beginning to take shape, with two BMW engineers taking the car to its limit.

Based on the new 4 Series coupe, the M4 gets more aggressive styling, with front design cues taken from the M6.

Under the bonnet, the M4 is tipped to use a twin-turbo straight six that will produce around 335kW.
