INDIANAPOLIS — Colin Mullan will again co-drive the No. 36 Window World-MI Windows and Doors Sprint X McLaren along with Jarett Andretti during the upcoming Pirelli GT4 America season.

The returning Mullan raced alongside Andretti during four Pirelli GT4 America Sprint X events in 2019.

“It was great to share so many podiums with Colin last season,” Andretti said. “For a driver of his age, I think his experience and record speaks for itself. We’re happy to have him back and I look forward to winning more with him.”

Mullan shared Andretti’s excitement.

“I’m very excited to be joining Andretti Autosport and Jarett Andretti for the 2020 GT4 America Sprint X championship,” Mullan said. “Jarett and I meshed very well as co-drivers during my partial season with the team last year. The whole organization has been a pleasure to work with, and I was welcomed into their family immediately. It’s been amazing to work with both McLaren and a team that carries such a pedigree in racing, and I’m looking forward to continuing that relationship into the future. I have no doubt that we’ll be a serious contender for podiums and race wins this year.”

The Pirelli GT4 America Sprint X series features a 60-minute race with a halfway pit stop and driver change.  Mullan and Andretti will each drive for 30-minute intervals. The season kicks off on March 7 at Circuit of the Americas in Austin, Texas.
