What Happened

Over eight days, a preproduction 2027 Corvette Grand Sport competed in One Lap of America, a demanding event that combines timed racing at multiple venues with long highway drives between them. Starting with a wet skidpad and facing a points deficit, the team climbed through the standings to finish seventh overall and second in the Stock GT class. The car, equipped with the Z52 package and Michelin PS4S tires, ran without any mechanical issues.

One Lap of America Progress
  1. Day 1

    Wet skidpad challenge; slow start leaves team in 52nd overall.

  2. Day 2

    Nashville Super Speedway roval: Simrell places 11th and 12th, vaulting car to 20th overall.

  3. Day 6

    Slinger Speedway oval (first Grand Sport on an oval) and Road America: enters top 10 overall.

  4. Day 7

    Blackhawk Farms: strong points day moves car to 7th overall, 2nd in class.

  5. Final day

    Dry skid pad at Tire Rack: Simrell finishes 16th, securing 2nd in class and 7th overall.

This was an incredible week and a true testament to this team and beyond. The car ran flawlessly all week with zero issues.
Andrew Abbott, GM vehicle performance engineer
