Global Rallycross Announces New Class
Image
Global Rallycross (GRC) recently unveiled GRC Lites, a new rallycross class that will support the series’ wildly popular Supercars class at all US races in 2013.
GRC Lites is a tightly controlled “spec” class, designed with an emphasis on driver skill. Built by top rallycross preparer OlsbergsMSE, Lites produce just over half the power of the top Supercar vehicles and are designed to be more manageable for developing star drivers.
“The racing is going to be close, since all cars conform to the same specification, and driving talent will be the deciding factor in these races,” said OlsbergsMSE CEO Andreas Eriksson, who worked with GRC to develop the class. “There is no better place than GRC Lites competitions to learn the sport.”
GRC Lites cars are purpose-built racers that are fast, nimble, and exciting to watch. They are all-wheel drive and capable of handling the jumps, door-to-door combat and surface changes of a typical rallycross course.
The class will run as a support series on the same courses as the Supercars at all US GRC events, with the Last Chance Qualifiers and Finals expected to run immediately before the main Supercar races.
At the conclusion of the 2013 season, the GRC Lites series champion will be awarded a drive in an OlsbergsMSE Ford Fiesta ST Supercar and the top three finishers in the championship will receive a Supercar test with OlsbergsMSE.
Rallycross is a blend of circuit racing, off-road racing and rally competition. It promises intense, crowd-pleasing action in a fan-friendly track environment. As many as 10 drivers line up to start at once, piloting high-horsepower compact cars through race traffic over a challenging short course that features jumps, unbanked turns and changing track and surface conditions that can include dirt, gravel, and wet and dry tarmac.
GRC introduced the sport to the United States with the first event held at X Games in 2010. For the past two years, the series has been limited to top-spec Supercars, which are production-based, turbocharged, all-wheel drive vehicles that produce 600 horsepower and go 0-60 in two seconds. The OlsbergsMSE GRC Lites are the only other vehicles homologated for GRC competition.
Technical partners include AEM (electronics and engine controls), Motegi Racing (wheels), Mountune (engine), Avitas Motorsport (chassis and bodywork), Sadev (transmission and driveline components) and OlsbergsMSE.
