Cadillac's upcoming 3 Series fighter will come standard with a 4-cylinder engine reports GMI, in a bid to keep weight low but more importantly to reduce emissions. But don't think that means it will be low on power. The 4-cylinder is most certainly going to be a turbocharged unit, along the lines of the 255-hp 2.0T engine offered in the Buick Regal GS.
The next-generation CTS is also set to be equipped with a base 4-cylinder option, although even more exciting engine options are planned including both a V6 and V8. The V8 will be a small block unit currently under development and will find its way into the third-generation CTS-V (which is still a long way off). An ATS-V model is also likely to feature this V8 engine. First, however, we'll get a taste of GM's upcoming twin-turbo V6 in the CTS, reportedly displacing 3.0-liters and set to rival Ford's EcoBoost V6 motor.
A possible match-up to both the twin-turbo V6 and V8 engines would be a new 8-speed dual-clutch automatic transmission that GM is now researching. We have to think that some sort of 8-speed box will find its way into GM's Alpha rear-drive cars considering BMW appears poised to run with 8-speed autos in the upcoming 3 Series and Audi will do the same in the A4.
Both the ATS and CTS are based on the same Alpha rear-drive platform, although the CTS underpinnings will be stretched quite a bit. The Alpha platform will also be used for the next-generation Camaro – suggesting it will be smaller and lighter than the current model. It could then also feature smaller turbocharged motors. Even more interesting is news that Buick is looking to utilize the Alpha platform in one of its products. Grand National anyone?
The timeline for these products will have the ATS Sedan launch in 2012, followed by an ATS Coupe and new CTS in 2013, with an ATS Convertible later that year. GM will most likely move ahead with plans for V versions of both the ATS and CTS but don't look for them until at least 2014.
