Before Rory Byrne became a legendary, championship-winning Ferrari Formula 1 engineer, he designed race cars for a little British firm named Royale. Designed by Byrne himself, this 1970 Royale RP4 is a formidable competitor in HSR Vintage Endurance and Group 3 racing. It is completely sorted and ready to race.
Since 1998, the car has been restored and maintained by Andy Greene, who formerly owned the Royale Race Cars company. A 1700cc aluminum twin cam Lotus racing engine provides 211hp, built and tuned by Savannah Race Engineering. Mated to the engine is a 5-speed Hewland gearbox, and the car has been converted to right-hand shift. Other upgrades include a Royale RP6 nose, a conversion from rubber drive donuts to CV joints, and a new ATL fuel cell installed in 2015. The car will also come with extra wheels and gear sets.
In 2001, this RP4 won the Rolex Vintage Endurance Championship. At the Classic Motorsports Mitty in 2016, it claimed Group 3 victory at Road Atlanta, with Elliot Forbes-Robinson behind the wheel. With capable hands at the controls, this competitive, exhilarating car could very will win the HSR Vintage Endurance title.
