Cadillac got serious about building a world-class luxury sports sedan when it designed, engineered, and tuned the ATS. Based on a rear-wheel-drive platform crafted to deliver the ride, handling, and performance of European rivals from Audi, BMW, and Mercedes, the Cadillac ATS was a dynamic hit let down by a lack of attention to detail. During the car's lifespan, from 2013 to 2019, it came in two-door coupe and four-door sedan body styles. Four-cylinder and V6 engines (with or without turbocharging) powered the rear wheels, and all-wheel drive was an option. In addition, the ATS-V models offered a significant performance upgrade, and Cadillac even offered a manual transmission for the ATS. After a heavy refresh for 2020, Cadillac changed the model's name to CT4.
