The coupe has the same wheelbase as the CTS, but an overall height that is approximately two inches (51 mm) lower and an overall length that is two inches (51 mm) shorter.
According to Cadillac, even though the Coupe is based on the CTS sedan, it shares only the instrument panel, console, headlamps, front fenders and grille with four-door model.
At launch, the 2011 CTS Coupe will be offered with GM's direct injected 3.6-liter V6 engine that produces 304 horsepower and offers an EPA-estimated fuel economy of 27 mpg on the highway.
The V6 engine is coupled to a standard 6-speed manual gearbox with an automatic transmission with Driver Shift Control and available steering wheel mounted shift buttons offered as an option. It will also come with rear- or all-wheel drive.
According to a previous announcement from GM, the CTS Coupe V6 will be joined in the near future by a range topping "V" model boasting the same 556-horsepower 6.2-liter supercharged V8 found on the CTS-V Sedan.
The CTS Coupe's hardware includes an independent short/long arm (SLA) front suspension system, with hydraulic control arm front bushings, and a multi-link rear suspension. Also included are four-wheel disc performance brakes, a limited-slip differential and GM's electronic chassis control system (StabiliTrak).
There are no pictures of the interior but Cadillac says that features include hand-sewn accents covering the door, center storage console and instrument panel trim as well as several techno goodies such as the 40GB hard drive, pop-up navigation system, rear camera and Bluetooth connectivity.
The option list will include a set of 14-way adjustable Recaro sport seats that were previously exclusively offered on Cadillac's V-Series model
We'll have more on the CTS Coupe at the LA Auto Show in December.
