When the times GM is reporting aren't official, how can anyone compare anything. What you want are: average speed, top speed, average corner entry, average corner exit, and average straight speed. Then, and only then you can compare cars in the same class. A Carrera will beat you on the corners, which is where nuerburgring is the toughest. The car that was run on Nuerburgring had a full roll-cage. Makes me wonder what other modifications were made to it just for the sake of publicity. I seem to remember a few weeks back Chevvy claiming a top Nuerburgring record too. Looks like claiming to have a new record without substantiating evidence, or even official times is the new fad for the American auto industry.
