Petit LeMans, Saturday 11 am to 9:30 pm, EST from road Atlanta, on Speed channel. Set those DVR's.

The November issue of Road & Track does a comparison between the street & ALMS GT class race versions of Corvette, Ferrari, Porsche, BMW & Jaguar. The similarities between the two are surprising. Yes, they are different, but are as close as can be when considering that one is a street car & the other is a race car.

EDIT: Time change. Had originally noted that the event started @ 9 am. Changed to the correct starting time of 11 am.
