Of course it's a real Bentley Flying Spur.Magnificent Bentley Phaeton Spur VR6 GT-R W-spec.
I agree it seems to be a real Bentley; by the way isn't the W12 a combination of 2 VR6? We have to look on the other side wether there is a second VR6 badge.
And you are right, the twinturbo W12 used in the Bentley is a combination of two VR6 engines side by side. Hence the W-shape. Plus: The Flying Spur is essentially a Volkswagen, a Phaeton to be exact.
So, except for the GTR badge, the guy is not totally off!
