Here are the latest spyshots of the next generation F80 BMW M3 Sedan undergoing winter testing in Sweden.
Compared to the previous spyshots, the M3 prototype has lost a some camouflage – showing the rear light clusters as it will look when the car enters production some time this year.
The engine is a topic for much rumor and is expected to be a 3.3l V6 Twin Turbo with an electronic KERS device which is the apparent third turbocharger.
We expect the power to be around 450hp with also additional chassis and engine weight reduction we expect this to be the fastest M3 yet.
Expect a public debut sometime after summer perhaps at the Frankfurt IAA in Production Concept form.
