General Motors North America President Mark Reuss unveiled this teaser photo of the 2013 Cadillac ATS Thursday morning, and otherwise confirmed pretty much everything we've reported and/or speculated on regarding the future Cadillac lineup.
"For now, this vehicle will be known by its code name; ATS," Reuss said about the Caddy 3 Series fighter that goes on sale in the summer of '12 as a 2013 model, speaking at the Center for Automotive Research's Management Briefing Seminar in Traverse City, Michigan Thursday morning.
"It's being developed to be a driver's car on an all-new Cadillac-specific RWD-AWD architecture, just like the larger CTS."

The ATS codename won't stick, and as far as we're concerned, this would be a good time to revert to real names for Cadillac models. That's not going to happen, as Reuss also announced the new transverse-engine large sedan, the XTS, goes on sale next spring. It's based on the XTS Platinum Concept unveiled at the '10 Detroit show, and though it's a front-drive-based all-wheel-drive sedan, it will be positioned as a more luxurious, more formal sedan to the CTS.
At a press conference after his CAR conference speech, Reuss confirmed that the next CTS, expected in the 2015 model year, will get larger. He wasn't explicit about it. The current CTS is a "tweener," he said, and the next one will directly compete with foreign competition, meaning the BMW 5 Series and Mercedes-Benz E-Class.

We expect it to get a more formal roofline, too, adding to the perception that it's a bigger car. The ATS teaser photo shows that car taking up the sporty sedan mantle from the CTS, with a profile and c-pillar that mimics the current CTS's design language.
The XTS and ATS models "will bracket the CTS sedan, coupe and wagon family," Reuss said. The smaller Caddy will come in all those bodystyles, while the XTS is designed to be a sedan only, replacing the DTS. We expect the ATS coupe to have a more formal roofline than the rakish CTS coupe's, making production of an ATS convertible much easier and more cost-effective. Latest intel indicates the ATS convertible will have a ragtop, rather than a folding steel roof.
GM is investing $117 million in the Oshawa, Ontario, assembly plant to build the new XTS.

The CTS is slated to migrate to the ATS's Alpha platform with the next model, as will the 2014 Chevrolet Camaro. We expect a new sedan and probably a coupe, though only the smaller ATS will come in a wagon bodystyle. A bigger, S-Class-size rear-drive Cadillac flagship is expected on the new Omega platform by the 2016 model year.
Reuss also announced pricing for the new eAssist version of the 2012 Buick Regal. The option retails for $2,000, and the car is rated 25 mpg city/36 mpg highway with the 2.4-liter I-4/mild hybrid powertrain.
