Forget the Off Season, it’s the 25 Hours of Thunderhill

December 4, 2015

The 25 Hours of Thunderhill presented by Hawk Performance is the longest major sports car endurance in North America. Offering a pleasant respite from the wasteland of the off-season, the 13th running of this great race offers plenty to be excited about.

Sixty-seven entries among seven different classes, including the newly revealed Elan Motorsports NP01 NASA prototype,  will take to the hilly three-mile, 15 turn road course for a total of 25 hours. The National Auto Sport Association, NASA, has sanctioned the low-key, cult classic event since 2002.

This year’s event will boast a variety of machinery across those seven classes including Porsche GT3 Cup, Lotus Exige, Wolf, BMW M3, Nissan 370Z, Audi R8 LMS, Mazda Miata MX-5 and RX-8, Radical, Acura ILX,  Factory Five Racing, Ginetta LMP3, NPO1 Prototype, and more! The variety of talent rivals the cars we’ll see with names like Al Unser Jr, Ryan Eversley, Darren Law, Dion von Moltke, Kurt Busch, Mike Skeen, Randy Pobst, and Burt Frisselle. Full driver and team entry lists are linked below.
