The Pirelli World Challenge (PWC) has become increasingly difficult for Cadillac and its CTS-V.R race car , which now faces competition from lighter and more powerful GT3-spec machines. Mercedes AMG , McLaren , Lamborghini and Porsche have all joined the PWC series in 2014, preventing the CTS Coupe-based racer from winning more than three events in 2014. Cadillac is in dire need of brand-new vehicle and word has it the manufacturer is already testing a brand-new chassis for 2015.
According to Racer, the next-generation Pirelli World Challenge car was seen lapping the Gingerman road course in Michigan in late-August 2014. While there’s no actual footage or photos of the vehicle, the source claims the new chassis will drop the CTS-V Coupe body in favor of an ATS-V Coupe -based shell. A new body could also mean a new engine, as Cadillac is expected to drop a twin-turbo V-6 in the yet unconfirmed ATS-V.R. The current race car is motivated by a naturally aspirated, 6.2-liter V-8.
As with its predecessor, the ATS-V-based track car is also developed by longtime Cadillac Racing partner Pratt & Miller engineering.
