....Looks like a Photoshop speculation by someone 'W12-ing' a Mk6. Look at the rear window intakes and flat engine cover in the back.
I don't think VW can call it a "GTI-R" anyway because of Nissan. ".:R20" would be more descriptive as the rumours are a 2.0T engine of some sort in a AWD. But I'm not sure it's been decided yet whether to even produce such a car - It's all speculation. Also, such a car would reduce Mk6 GTI sales wouldn't it?
