Riley Technologies is the brainchild of designer Bob Riley and his son Bill Riley. The company was originally founded in 1990 as Riley & Scott Inc. Over the years the company has evolved with Reynard buying Riley & Scott Inc. Over the last twenty years the company has built over 100 racecars for IRL, Trans-AM and FIA GT. Their newest car, the Mk XI Daytona Prototype, was accepted to run in the 2003 Grand-Am Sports Car series.

Riley’s Dayonta Prototype was built on the company’s engineering expertise in constructing steel tube/aluminum reinforced chassis with excellent mechanical grip and an outstanding aerodynamic package. Suitable for installation of any class-eligible motor, the car was equipped with the proven Xtrac gearbox used in the Mk III C and many other top SR1/LMP 900 chassis.

In the recent past Riley have been dominating the top level of Grand-Am motorsport. This is largely due to Chip Ganassi Racing and Sun Trust Racing which both use the Mark XI, but with different engines.
