Bob Riley and Bill Riley established Riley Technologies in 2001 following their departure from Riley & Scott, the constructor responsible for several prominent sports prototypes in the 1990s. The company relocated its headquarters to Mooresville, North Carolina in late 2006, placing it among the dense concentration of motorsport businesses in that region.
Riley Technologies became the principal constructor of the Daytona Prototype chassis used in the Grand-Am Rolex Sports Car Series. The Riley chassis proved dominant across the series, both in terms of car count and outright results. Seven wins at the 24 Hours of Daytona with Riley chassis were recorded across the Daytona Prototype era.
The 2005 24 Hours of Daytona was won by SunTrust Racing using a Pontiac-Riley. Chip Ganassi Racing then claimed back-to-back-to-back victories in 2006, 2007, and 2008 running Lexus-powered Rileys. In 2009, Brumos Racing won with a Porsche-powered Riley, followed by Action Express Racing claiming the 2010 edition with another Porsche-engined example. Chip Ganassi Racing returned to the top step in 2011 using a BMW engine, and again in 2015 with a Ford engine following the creation of the United SportsCar Championship.
When the United SportsCar Championship formed in 2014, Riley adapted its Daytona Prototype to Generation 3 regulations, making the cars competitive against former American Le Mans Series LMP2 machinery. Customer teams including Chip Ganassi Racing, GAINSCO/Bob Stallings Racing, Mike Shank Racing, and Starworks Motorsport ran Riley chassis during this period.
In 2017, Riley became one of four manufacturers homologated for the new LMP2 and DPi categories introduced to the IMSA SportsCar Championship. Their entry was the Riley-Multimatic MkXXX, developed in partnership with Multimatic. Under the arrangement, Multimatic handled the carbon fibre tub, bodywork, and aerodynamics, while Riley designed and manufactured the mechanical components, including suspension, and assembled the finished cars. By June 2017, Multimatic had taken the commercial lead on the LMP2 aspect of the programme, while Riley led the DPi variant.
Beyond prototype racing, Riley Technologies built the Mazda RX-8 race car for SpeedSource, which won its class at the 2008 24 Hours of Daytona. Riley also developed a BMW M6 GT race car revealed in 2008 and built a GT2-class Chevrolet Corvette for the 2008 American Le Mans Series.
The SRT Viper GT3-R was jointly developed by SRT Motorsports and Riley Technologies, competing in IMSA GTD, the Pirelli World Challenge, and the Dutch Supercar Challenge. Following SRT's factory withdrawal after the 2014 season, Riley ran customer Mercedes-AMG GT3 cars in the IMSA GTD class from 2017 onwards, with Ben Keating and Jeroen Bleekemolen as regular drivers. That pairing won the Endurance Cup in 2019.
In 2019, Riley also entered the IMSA Michelin Pilot Challenge with a Mercedes-AMG GT4, with drivers Jim Cox and Dylan Murry winning the Daytona season opener. The team subsequently moved to the LMP3 class in the IMSA WeatherTech Championship for 2021.
In 2025, Riley expanded its programme with a dual-class entry in the IMSA SportsCar Championship. Alongside their Oreca 07 in the LMP2 class, Riley took over the GTP Lamborghini SC63 programme from Iron Lynx, running the car under the Automobili Lamborghini Squadra Corse banner. Factory drivers included Mirko Bortolotti, Romain Grosjean, Daniil Kvyat, and Edoardo Mortara.
Riley Technologies' chassis dominated the Daytona Prototype era more thoroughly than any competitor, accumulating seven Daytona 24-hour victories with multiple engine partners. The company's ability to adapt across regulatory generations — from Daytona Prototypes through Gen 3, LMP2/DPi, GT programmes, and GTP service roles — established it as one of the most versatile and durable constructors in American sports car racing history.
