GM is currently working on a new smaller rear-wheel-drive sedan, known as the ATS, which will sit below the CTS in the lineup. The ATS is based on a new Alpha platform that will also be the basis for the next Camaro. Originally GM had planned on releasing sedan, coupe, convertible and wagon variants of the ATS, but unfortunately the plans have changed.
According to GMI, GM has canceled plans for a convertible version of the ATS due to its lower volume. An unnamed source stated that that the convertible was axed because volume projections were not high enough to justify the extra development costs. The ATS wagon is also not gonna happen, since plans for that model were apparently killed before the program was finalized. Luckily plans for a coupe are still on.
The ATS sedan will arrive in 2012 with a new version of GM’s 2.0-liter turbocharged four-cylinder and a 3.6-liter V-6. All-wheel-drive is also reportedly going to be offered. Although we will see the sedan sometime next year, the coupe isn’t expected to arrive until 2015.
