SALT LAKE CITY, Utah – With nearly 100 guests on hand to cheer on the “home team,” Salt Lake City-based Magnus Racing will return to competition at Utah Motorsport Campus this weekend for the first time since 2010.

“It’s great to be back in Utah, and we look forward to being the local favorite,” stated Magnus Racing team owner and driver John Potter. “Utah Motorsport Campus has been a home for me for quite a while now, having rented a garage there for nearly a decade and lived in Salt Lake City even longer. It’s a tremendous locale with a great fan base, and everyone on the team is committed to delivering a first-rate event for them.”

Returning to the Pirelli World Challenge series for the next round of “SprintX” competition, the team will bring two cars with four drivers to the event. Even though all races are only 60 minutes in length, “SprintX” is designed to reflect the endurance heritage of sportscar racing, with multiple drivers sharing the same vehicle.

Driving the No. 4 Audi Tire Center Audi R8 LMS, Pierre Kaffer and Spencer Pumpelly will once again re-unite for the weekend. Pumpelly is joining the team after a difficult weekend in Mid-Ohio, while Kaffer returns to the team after missing the last round due to a schedule conflict. While the two have not driven together since May, the last SprintX race for the No. 4 car at Lime Rock Park was the most successful to date, taking victory.

For the No. 44 Audi Tire Center Audi R8 LMS, long-time teammate Marco Seefried will once again join John Potter behind the wheel, continuing a partnership that began with victory at the Mobil 1 Twelve Hours of Sebring in 2014. So far in 2017, the duo have taken part in two different SprintX weekends, driving with mixed results and taking a top finish of fourth.

Official practice begins this Friday, August 11, with the GTX category featuring a double-header race weekend. Racing will take place at 1:40PM on Saturday and 12:30PM on Sunday. Live streaming can be found at
