GM just broke news of the ATS powertrain lineup, and it's becoming clear that the new ATS will come in a wide range of performance flavors.
When the ATS hits the market next fall it will offer a choice of three different engines: a new 2.5-liter in-line four-cylinder, a 3.6-liter V-6, and a new-generation 2.0-liter turbocharged (2.0T) Ecotec four. It's expected that all three engines will be offered with either manual or automatic transmissions.
In an advance presentation to the press this afternoon, GM officials said that the new 2.0T four, which will be built at Spring Hill, Tennessee, will make its debut in the 2013 Cadillac ATS, and will produce 270 horsepower--that’s even more horsepower per liter than the BMW M3, Porsche 911 Carrera GTS, or Lamborghini Aventador.
With a new twin-scroll turbocharger delivering up to 20 psi of boost, the new 2.0T--really the star of the lineup at launch--should also be a step more responsive than GM’s current generation of turbocharged engines. What’s even more impressive is that the engine makes 90 percent of its peak torque from 1,500 to 5,800 rpm; those changes, to us, add some hope that GM's new performance engine for the lineup will have the sort of robustness and responsiveness of BMW's turbocharged fours and sixes.

The familiar 3.6-liter V-6 is the same engine that’s already offered elsewhere in the Cadillac lineup, in the CTS and SRX for instance, while the 2.5-liter engine is part of GM’s new Ecotec family and built in Tonawanda.
GM will likely reveal power numbers for the other engines, along with full details for the ATS, at the 2012 Detroit Auto Show in a few weeks.
