While we don't have official word on the powertrain yet, we do expect the ATS-V will be the first turbocharged Cadillac V car, with a version of the 3.6 liter twin turbo that is found in the CTS Vsport. In that car, it makes 420 horsepower and 430 horsepower, which are similar numbers to the brand new BMW M3 and M4 twins. We'd expect that Cadillac will bump that up for the ATS-V, something about 450 horsepower feels right for this application.
