Riley Technologies LLC is an American auto racing constructor and team which specializes in the design and manufacture of complete race cars, as well as prototype development for racing and manufacturing applications.
In 2001, Bob Riley and son Bill, formerly of Riley & Scott formed Riley Technologies. The company moved their headquarters to Mooresville, NC in late 2006.
Riley Technologies was the leading constructor of the Daytona Prototype chassis for the Grand-Am Rolex Sports Car Series. The Riley chassis was dominant in terms of both numbers of cars on the grid and results.
Riley chassis have won seven 24 Hours of Daytona races with different engines, the 2005 race was won by the SunTrust Racing Pontiac-Riley and 2006, 2007, and 2008 victories went to Chip Ganassi Racing Lexus powered Rileys. The 2009 race was won by a Brumos Racing Porsche powered Riley. In the 2010 race, another Porsche-powered Mark XI from Action Express Racing won. The 2011 race was again won by Chip Ganassi Racing, this time with a BMW engine.
When the United SportsCar Championship was created in 2014, Riley continued as Daytona Prototype supplier, with Gen3 rules adopted to make the cars competitive versus the former ALMS LMP2 cars. The company supplied the Ganassi, GAINSCO/Bob Stallings, Shank and Starworks teams. Ganassi became the only full-time team in 2015, and no full-time entry used Riley chassis in 2016.
In 2017, Riley will become one of the four LMP2 and DPi chassis manufacturers. The car was developed in partnership with Multimatic. The DPi entry will be Mazda branded.
Riley developed the Mazda RX-8 chassis that won the GT class in the 2008 race. Also unveiled in 2008 was the BMW M6 GT race car.
