Action Express Racing was founded in 2010 and ran in the former Rolex Sports Car Series. The team started out of the gate strong, by winning the 2010 Rolex 24 at Daytona. Their lineup in the No. 5 Riley Mk. XI featured João Barbosa, Terry Borcheller, Ryan Dalziel, and Audi LMP1 driver Mike Rockenfeller. The team's win was notable as their engine, a Porsche 5.0L V8 engine, was not sanctioned by Porsche itself, and was built by a third party based on the Porsche Cayenne. Full season drivers Barbosa and Borcheller were joined by J. C. France for a few rounds, but did not find the podium again, finishing 13th in points. Barbosa, Borcheller, and France reunited the following season, taking a podium at the 2011 Rolex 24 and winning at Virginia International Raceway, enough for Barbosa and France to finish 5th in points. The team also expanded to the No. 9 Riley-Porsche, driven by Darren Law, IndyCar driver Buddy Rice, David Donohue, and Burt Frissele. After reuniting Barbosa and France, the team opted to replace the latter with Law, scoring wins at Belle Isle and the 6 Hours of Watkins Glen.
