At 3 a.m., on lap 360, the No. 100 M6, with Lucas Luhr behind the wheel, suffered a heavy crash in turn one, impacting the front and rear of the car.
Luhr was unhurt, but the damage from the suspected mechanical failure forced the team to retire the car from the race.
“Something failed, but I don’t know what exactly,” Luhr said.
Congratulations to the Rahal Letterman Lanigan 25 car team on their win today at Circuit of the Americas. John and Lucas ran a solid race on an alternate pit strategy that should have given them a shot at the top 3. Unfortunately John suffered a left front puncture with 15 minutes to go.
