Production Ready BMW M6 Cabrio spotted

Our trusty Teamnspeed spies bring us the best pictures to date of BMW’s new M6 in cabrio guise. The new M6 is rumored to become a true monster when it will hit show rooms in spring 2012. Equipped with the sophisticated 4.4-litre bi-turbo V8 known from the X5 and X6 M-versions, the new M6’s motor will develop roughly 570 to 580 hp.

The car was snapped close to BMW Germany’s headquarters. As you can see it was riding on giant 20-inch wheels, and we reckon that yet bigger ones will be available as an option. Stay tuned for more developments.
