This won't be the last time you see the Cadillac ATS on the NürburgringMike Spinelli9/16/11 3:30pmFiled to: cadillac atsCadillacNurburgringatsats-vVideoClips70EditPromoteShare to KinjaToggle Conversation toolsGo to permalink A Cadillac on the Nürburgring? What are the odds? Sure Cadillac's never met a Nürburgring it didn't lap, but this is the best we've seen of the company's upcoming 3-Series competitor rounding graffiti street.That subdued engine note of the Cadillac ATS points not to a V8, however, but one of the new car's lesser-piston'd powerplants. GM North America boss Mark Reuss has said, in a recent video clip, that "Cadillac shouldn't be just about big V8s and supercharged motors." And so, that's led most speculators divining the top-line ATS-Vs powertrain down the V6 trail, with a logical assumption being it'll be a highly worked version of the Camaro's 3.6-liter. That's likely considering the BMW's reportedly returning to six-cylinder power for the next-gen M3.
