Our spy photographers just snapped the first photos of a prototype 2015 Cadillac ATS-V coupe out testing, and it appears that the BMW M4 will face some stiff competition. This is also our best look at a coupe version of the ATS, which we've spotted before wearing much more camouflage.
Spy photographers have spotted something interesting. Cadillac engineers have taken to public streets with the upcoming ATS-V and a playmate: the current BMW M3 Sedan. The prototype seen here wears a more aggressive front fascia, flared fenders and beefy brakes. Quad exhaust tips and what looks to be a small lip spoiler on the trunk deck sum up the most obvious visual changes over the standard ATS outside. Word has it the ATS-V will bow with the same twin-turbo 3.6-liter V6 available in the nose
