The 2019 Corvette ZR1 was the official Pace Car for the 2018 Indianapolis 500 presented by PennGrade Motor Oil and led drivers to the green flag on Sunday, May 27, for the 102nd running of the legendary race. It marks the 15th time a Corvette has served as the official Pace Car since 1978, and the 29th time a Chevrolet has led the field dating back to 1948, when a 1948 Fleetmaster Six convertible paced the race.
