Let's be clear about something here: The CTS-V Challenge was not, strictly a clean race. It was a publicity stunt. Cadillac acknowledges this. Still, as a publicity stunt, it was a hell of a lot more fun than basically every other car-maker publicity stunt we've attended.

And it's a stunt that a young guy, who claimed to be a Skip Barber school graduate but not a racer, won in his BMW M3. His fast lap of 2:50:424 was the fastest single lap of any driver that wasn't a ringer (Heinricy, Link and Redman). No other CTS-V could touch him.

Here, for the record, are the final lap times of the day:

Mystery Driver (Johnny O'Connell), CTS-V, ringer, 2:45:537

John Heinricy, CTS-V, ringer, 2:46:560

Aaron Link, CTS-V, ringer, 2:48:902

Brian Redman, CTS-V, ringer, 2:49:596
