So after the official event was over, a silver CTS-V circled the track stupid fast and occasionally sideways. He was listed on the timing and scoring screen as "Mystery Driver." Very intriguing, no?

Who was this man who posted a fastest lap of 2:45:537? Was it Cadillac's Stig? Well, sort of.

Speed TV was out filming the days event for an upcoming program with a full crew. Yes, there was a helicopter involved. Seems the folks at Speed wanted to have a little extra angle on this event since it's been blogged to death already (trust us, we know). So they brought their own driver and refused to say who it might be. But to beat Heinricy, he'd have to be a pro.

That cover was a bit blown when we saw Corvette racer Johnny O'Connell travel out of Monitcello in a 'Speed" racing suit.

"Nice driving, Johnny," we say.

"Oh thanks, that was fun."
