You're making this too easy...
That would be Juan Pablo Montoya. He and Gordon swapped cars to run the road course at Indy as publicity for the USGP in September.
Gordon lapped 1.3 seconds slower in Montoya's Williams/BMW; Montoya was 1.1 slower in Gordon's Chevy.
The best time set by Gordon in his own car was a 1:38.8; the best time from Montoya in his own car was a 1:15.2. "Somewhat close" was 23 seconds slower, over a 30% difference.
There is no doubt that Montoya was alot quicker but, Back to my statement earlier. COuld Montoya runs those laps with 40 other cars on the track? Maybe. Would he make it the whole race? Odds are no.
How many other racing sports put 40 to 42 cars on the same track that are only seperated buy a second (sometimes more). Knowing that if you make one wrong move you have in your hands the lives of so many other people?
