Just the Facts:

The 2013 Cadillac ATS compact sedan will offer a choice of three different engines.
A 270-horsepower, 2.0-liter turbocharged four-cylinder could be the enthusiast choice for ATS power.
Normally aspirated options are a 2.5-liter four-cylinder and a 3.6-liter V6.


WARREN, Michigan — General Motors detailed the engine lineup for its 2013 Cadillac ATS compact sedan here today, leaving how it drives as about the only thing we don't know about Caddy's all-new 3 Series fighter, which officially debuts at the 2012 Detroit Auto Show in a few weeks. The three engine choices are highlighted by a 2.5-liter four-cylinder and a turbocharged 2.0-liter four-cylinder from GM's all-new Ecotec architecture that engineers say is almost totally new and different from the current-generation Ecotec family.

While GM brags that the direct-injected 2.0-liter turbo's 270 horsepower makes it one of the most power-dense production engines available, the familiar 3.6-liter dual-cam V6 already used in Cadillac's CTS midsizer (making 318 horses this year) likely will be positioned as the ATS's top engine. Nonetheless, the 2.0-liter turbocharged four-cylinder looks to be the enthusiast choice, what with the turbo's wide torque band — 90 percent of peak torque of 260 pound-feet is available all the way from 1,500 rpm to 5,800 rpm — and the fact it probably will mean less weight on the rear-drive ATS's front tires.

"This engine is the perfect match for the new ATS, which will be a refined performance luxury sedan," said Don Butler, Cadillac's vice president of global marketing, in a release. "The 2.0T has an exceptionally smooth and responsive power curve that will make the ATS nimble, quick and fun to drive."

Mike Anderson, chief engineer for the 2.0-liter turbo engine, said friction has been cut by 16 percent and complex computational fluid dynamics work helped optimize power and torque output while balancing the ever-increasing concerns for fuel economy. That two of the three ATS engine choices are four-cylinders is no surprise, given pending Corporate Average Fuel Economy regulations that have led even Germany's vaunted performance sedans such as the 3 Series and Mercedes-Benz C-Class to move to turbocharged four-cylinder options.

Meanwhile, the entry point of the ATS lineup will be held by the normally aspirated 2.5-liter four-cylinder, also from the all-new Ecotec family. Power and torque figures have yet to be released by GM for the 2.5-liter, which also finds a home in the 2013 Chevrolet Malibu and is sure to quickly proliferate throughout GM's four remaining vehicle divisions.

Inside Line says: Getting 270 horses out of two liters is pretty serious stuff. We'll see if it's enough engine to hold up that part of the ATS's potential sport-sedan credentials.
