Spy Video: BMW F82 M4 Testing on the Nurburgring
Going over the numbers though, we're not so sure. We know it will be an inline-6 configuration, we know it's going to be turbocharged and a 3-liter unit but we don't know the power and torque output.
It will definitely be over 420 HP, we think, judging by the way the prototype in the video below simply flies over Nurburgring and its tight corners. The amount of torque will be over the chart, the rear end looking very happy.
The same unit will be used on the more conventional sedan, the F80 M3 that will probably make it to the market around the same time as the M4 Coupe.
