Spied: M4 Cabrio!

Taking the front end style of the 3-Series, BMW has given the new M4 and M4 Cabrio (seen here) a lower nose, flared arches and the trademark M side vents. The rear end retains a shape like the current convertible.

The new M4 Coupe and Cabrio models were will be reverting to an in-line six-cylinder, this one turbocharged. It is expected to have two sequential turbos and develop around 450 hp. Motorsport fans will be pleased to hear that though a V6 turbo engine was considered, BMW decided to stick with the traditional BMW layout of an in-line six cylinder engine.
