Yes, unfortunately, you may or may not notice, he didn't have the car in Manual Mode, or Sport... was a pathetic attempt... although it showed it win on the road course... If you've watched many of those episodes... it's all about 'TV Entertainment'... i've seen plenty of cars that should have won 'one contest or the other'... only to see them get it backwards...
I'm using my experience on the same tracks, same driver... and hands down.. it's no contest in a straight line (which is usually a brainless feat.. if you're smart enough to put the car in manual / sport mode... and shift when you hear the buzzer.. which none of that happens in that episode.
Then, you have C/D latest mag... so it not only beats the M3... but ties the M3 that runs sport cup tires...
