Two racing icons will unite when Lance Armstrong, seven-time Tour de France winner, drives the 2006 Chevrolet Corvette Z06 pace car to lead the field to the start of the 90th running of the Indianapolis 500 on May 28, 2006. For a record 17th time, a Chevy will pace the race, and it's the eighth time for a Corvette to be leading the pack. The only changes made to prepare it for this year's role were the addition of strobe lights and racing safety gear.
