The Penske Porsches Are Coming! The Penske Porsches Are Coming!

The Corvettes aren't the only ones heading out the paddock. With the Detroit Belle Isle Grand Prix ALMS race just 45 minutes away, the Penske Racing Porsche RS Spyders have up, revved and run their 480 horsepower engines out of the paddock just the same as their yellow brethren. These are the same Penske Porsches that seem to be running rather well this morning during the practice sessions.
