History

Following requests from SLR Club members, the British racing specialist RML Group developed the 722 GT in 2007. It is designed exclusively for the racetrack, has no road approval and was built to compete in the SLR Club Trophy. More than 400 components were redesigned, including the aerodynamics, interior and exhaust system.
