About the 2015 Cadillac ATS

1st generation ATS; 2015 is the sedan’s update year and the first year for the ATS Coupe.

Cadillac positioned the ATS as its driver-focused small luxury car: lighter than many rivals, balanced around rear-wheel-drive proportions, and tuned to feel nimble and responsive. The sedan served as a compact luxury sport sedan alternative to cars like the BMW 3 Series, while the new coupe added a sleeker style choice without changing the core mission. Cadillac sold the ATS on sharp handling, strong available engines, distinctive design, and upscale tech in a smaller footprint.

The 2015 ATS ranges from the straightforward 2.5-liter sedan to stronger turbo four-cylinder and V6 versions, with the turbo and V6 also represented by the new coupe. Luxury trims pair leather seating with an 8-inch touchscreen, while Premium models add a head-up display, upgraded Bose audio, and a power-adjustable steering column.

“I would like to see the gas tank, no matter what model vehicle, always on the driver's side of the car. I would like to have a flat back seat and cushion. I do not like a bucket seat at all!”

“What a great improvement the 2015 ATS Coupe is over the 2013 Sedan. From the ride, handling, overall performance, I couldn't be any happier or pleased with this car. It's stylish, sporty, and in my opinion, timelessly classy... Cadillac has found its mojo again. I cannot wait for the Cadillac Elmiraj....”
