We first heard about GM working on a 3.0L twin-turbo V6 powerplant almost two years ago and it was widely believed that the company would probably stick to only one twin-turbo V6 since its fifth generation of their small block V8 was also around coming. Now, reports are surfacing that GM does indeed have a second, 3.6-liter twin-turbo V6 in the works.
Looking back on 2009, GM and Jay Leno teamed up to build a Chevy Camaro Concept for SEMA that packed a 3.6L twin-turbo V6. Back then, the American automaker claimed it produced 425-hp, so it’s probably safe to speculate that a production 3.6L twin-turbo V6 from GM would have at least 400-hp.
The 3.0L twin-turbo V6 should make its way into the Cadillac XTS (pictured above) and CTS models with an eight-speed automatic transmission. The 3.6L however could be seen in the upcoming ATS-V performance car. The 3.6L twin-turbo V6 currently in development might only be seen in Cadillac models, though that’s just speculation.

According to a report by GMInsideNews, the ATS Convertible has been dropped as sales projections for the car proved too low to make up for the cost required to bring it to market. Early plans for a wagon version were dropped early on in the development of the new small rear-drive platform.
With the ATS sedan expected to arrive some time in 2012 as a 2013 model year car, a coupe version is still in the cards and is set to follow afterwards by a few months.
Power for the new ATS is expected to come from a version of GM’s 2.0-liter turbocharged 4-cylinder, with a 3.6-liter V6 optional. Look for V versions to arrive a year or two later, packing either V8 power or GM’s upcoming twin-turbo V6 engine.
The Cadillac ATS is a crucial product for GM’s luxury division, a car aimed squarely at the BMW 3-Series, and Cadillac is hoping to come out with a full line of models to give buyers an alternative to the German compact luxury cars.
One noticeable difference will be among the convertibles, as the ATS will not offer a folding hardtop like the 3-Series, but a less expensive soft top. Also being discussed is a turbocharged V6 in place of the familiar GM 6.2L Supercharged V8. The V6 was originally developed jointly with Fiat for use in Alfa Romeo cars and would have to be re-oriented to be used with a rear-drive application.

With yesterday’s announcement that GM is moving ahead with plans to build a new Cadillac model that will rival the BMW 3 Series, the team at GMInsideNews has some exciting info to share about the product rollout.
According to their sources, the new model (likely to wear the ‘ATS’ badge), will come standard with a turbocharged 2.0-liter 4-cylinder, with a V6 optional. The sedan will debut in the Fall of 2012 as a 2013 model, with a Coupe following the next year as a 2014 model and a Convertible shortly after that.
But the real excitement doesn’t come until 2015, when the ATS-V debuts. And while the others may get 4-cylinder or V6 power a V8 is planned for the high-performance version. There is, however, a strong possibility that GM could look to use its upcoming twin-turbocharged V6, which is also planned for the CTS.
