This is Cadillac's new GT3 racer, spotted being loaded on a cargo plane at Chicago's O'Hare International Airport. Coated in black-and-white psychedelic camo, it appears the race car is based on a 2015 ATS-V, but the Detroit carmaker has yet to make an announcement of any kind. The FIA's 2015 Balance of Performance test is happening at Ladoux, so there's every chance the racer was being transported to France as all GT3 models are required to appear for testing at Michelin's Proving Grounds to set next year's global baseline.
