INDIANAPOLIS – Andretti Autosport’s GT4 America Series SprintX team has announced today that David Donohue will take the co-driver position in the No. 36 Window World-MI Windows and Doors McLaren 570S alongside Jarett Andretti at Road America on Sept. 21-22.

Andretti, son of retired NASCAR and Indy car driver John Andretti, welcomes fellow multi-generation racer Donohue, the son of champion racing driver and Indianapolis 500 winner Mark Donohue.

“Having David join Andretti Autosport for Elkhart Lake brings a lot our program with his experience,” said Michael Andretti, CEO of Andretti Autosport. “With Window World and Mi Windows and Doors as the presenting sponsor of the GT4 America races, he will give us a great opportunity to have a strong finish in the Window World/Mi Sprint X McLaren.”

“We are all really excited to have David in the car for Road America. Like many other drivers, I’ve read his Father’s book ‘The Unfair Advantage’ and hope to hear some of those stories firsthand from David this weekend,” said Jarett Andretti. “I look forward to getting to work in a couple weeks and hope to put together a couple strong runs for Endurance and Window World.”

“It’s an honor to have David Donohue, son of esteemed race car driver Mark Donohue, join Jarett Andretti as a co-driver in the Window World McLaren for the upcoming GT4 America race in Elkhart Lake, Wisconsin,” said Tammy Whitworth, chairwoman and CEO of Window World. “Window World is thrilled to be the presenting sponsor of the GT4 America Series for the Elkhart Lake event, and we wish David all the best in his debut for Andretti Autosport.”

“I’m really looking forward to working with Jarett and the team,” David Donohue said. “I hope we can build on their win list, especially coming off a successful Watkins Glen weekend. I also owe a special thanks to McLaren of Philly and Newport Beach for their support and cutting me loose for the weekend. I’ve always admired this series so it especially gratifying to play a part.”

The son of racing legend Mark Donohue, David Donohue has accomplished much in a wide variety of auto racing series and classes, including NASCAR’s Busch Series and Craftsman Truck Series, as well as winning the GT2 class at the 1998 running of the 24 Hours of Le Mans.

Almost exactly 40 years after his father won the 24 Hours of Daytona, David won the 2009 event driving a Brumos-entered Riley-Porsche teamed with Antonio García, Darren Law and Buddy Rice. After starting the race from pole position, Donohue’s 0.167-second margin of victory over Juan Pablo Montoya was the closest in the race’s history by over a minute, and the closest finish in the history of major international 24-hour motorsports events. In 2013, David Donohue drove in the first GX class race at the 24 hour of Daytona. His car, the No. 16 Napleton Porsche Cayman S, won by a nine-lap lead.

Andretti, a graduate of North Carolina State University, lives in Indianapolis and races full-time. The third-generation racer is the son of John Andretti, the grandson of Aldo Andretti and the great-nephew of Mario Andretti.
