Spied: 2013 BMW M6 Coupe & Cabrio testing in North America

Here are the best pictures yet of BMW’s new M6 in both, coupe and cabrio form. The cars are rumored to become true Audi R8-fighters when they will hit show rooms in autumn this year. Equipped with the sophisticated 4.4-litre bi-turbo V8's from the X5 and X6 M versions, the new M6’s motor will develop close to 580 hp.

The cars were snapped in the U.S. desert earlier today, and our Teamspeed shooter was able to get a glimpse of the interior, too. Both prototypes were was riding on giant 20-inch wheels, and we reckon that yet bigger ones will be available as options...notice the brakes, they are huge!

This looks like an inside job. Thanks for leaking......

Looks sick. Love the carbon trim on the inside.

Hitting show rooms this year??? I thought not until next summer as 2013 models? Hey, the earlier the better though!
