The Cadillac ATS is actually a really fun car to drive in every trim, as it shares the same underpinnings of the latest Camaro and both engine choices give great life to the car. The first engine is a 2.0-liter turbocharged four-cylinder that puts out a solid 272 horsepower and 295 pound-feet of torque, which is enough to make the ATS feel fast. Fuel economy comes in at an EPA-estimated 22 miles per gallon city, 30 mpg highway, and 25 combined.
Higher trim levels get a 3.6-liter V6 that gives 335 hp, making it capable of hitting 60 mph in 5.3 seconds. This engine is also surprisingly efficient, as its use of cylinder deactivation allows it to be EPA-rated at 19/29/23 mpg (city/highway/combined)
The ATS comes standard with all-wheel drive with the exception of the rear-wheel-drive-only Premium Performance top trim, and the only transmission is an slick-shifting eight-speed automatic.
The real joy of the ATS lies in the corners, as it offers tons of grip. This is especially true at top trims that come equipped with stickier tires and GM's excellent magnetic-ride suspension adapted from the Corvette that can automatically change firmness almost instantaneously as the car moves over the road. Brakes are sourced from Brembo, and will scrub off speed with enthusiasm. It really is a shame not enough people bought this car, warranting its cancellation.
