Jim Harbaugh, who is currently the head coach of the San Francisco 49ers, has been chosen to drive the pace car for this year's race. He was a Quarterback for the Colts from 1994-1997.
Harbaugh is also a big racing fan, and is co-owner of Panther Racing, which which has two cars in the field for Sunday's race.
"As a longtime racing fan and someone who has always followed the Indianapolis 500, the honor to drive the Pace Car comes as a tremendous thrill," Harbaugh said. "Doing it in the all-new 2014 Corvette Stingray makes it even better. It's an iconic car leading an iconic race."
