Riley Technologies is an American race car constructor and team which participates in different American sportscar racing series since the foundation in 2001 and is the most successful chassis builder in the Daytona Prototype era, with ten Daytona 24h victories (between 2005 and 2015) and nine consecutive championship titles in the Rolex Sports Car Series from 2004 to 2012. The team also took championship title in the GTLM class of the 2014 IMSA United SportsCar Championship with SRT Viper GT car.

In 2017, Riley Technologies starts the new era of DPi prototypes with two different cars for Mazda Motorsports and Visit Florida Racing. In the GT racing, Riley Motorsports switches to Mercedes-AMG GT3 car.

Bob Riley continued a job of Riley & Scott company

Riley Technologies was formed in 2001 by Bob Riley and his son Bill. They continued the job of the Riley & Scott company which Bob Riley and Mark Scott founded in 1990. When Riley & Scott declared bankruptcy, Riley Technologies continued to produce and maintain their successful Riley & Scott Mark III prototype. The company is based in Mooresville, North Carolina.

In 2001 and 2002, the car was participating in the Rolex Sports Car Series and American Le Mans Series used by several teams. The Riley Racing went to Le Mans in June 2002, with Marc Goossens, Didier Theys and Jim Matthews in their #4 car, but they retired after 13 hours of racing due to engine failure.

Developing new Daytona Prototype

New regulations for the Rolex Sports Car Series were announced during 2002 which made the Mk III ineligible to compete from 2003 onwards, so Riley Technologies concentrated on their new Daytona Prototype. During the 2003 season, Riley’s old Mark III prototypes were still in use in the American Le Mans Series while the company was developing new Riley Mark XI prototype.

The Grand American Road Racing Association (GARRA) replaced their two premier open cockpit classes, known as SRP-I and SRP-II, with closed cockpit chassis made out of tube frames, instead of high-cost fiber composites.  To reduce costs, GARRA didn’t allow major manufacturers to run Daytona Prototype teams and seven manufacturers have been chosen to built DP chassis: Chase, Crawford, Doran, Fabcar, Multimatic, Picchio and Riley. The GARRA was also regulating who would provide engines.

Riley Mk XI debuted in 2004

In 2003 Rolex Sports Car Series, only six Daytona Prototypes were running, without Rileys in the competition. In 2004, when SRP class was finally banned, the number of DP cars increased to 17 at the season opener at Daytona.

Chip Ganassi Racing with Felix Sabates was running two Riley Mk XI prototypes (numbers 01 and 02) with Lexus engine, SunTrust Racing was using a #10 Pontiac-powered car.

SunTrust Racing’s Wayne Taylor and Max Angelelli scored the first victory win in Phoenix in April. After that, their #10 car was victorious three more times, the #01 car added four wins, driven by Scott Pruett and Max Papis.
