The 2015 Cadillac ATS delivered with punchy performance and poised handling, cementing Cadillac's bid for sport-luxury domination. Available as a coupe or sedan, the ATS offered three engines: a 2.5L four-cylinder with 202 hp, a turbocharged 2.0L four-cylinder with 272 hp, or a 3.6L V6 with 321 hp. All models used a 6-speed automatic transmission, with a manual available on certain 2.0L turbo configurations. Rear-wheel drive was standard, but all-wheel drive was optional. The ATS thoroughly embraced technology with the CUE infotainment system, an 8-inch touchscreen, Bluetooth, and available 4G LTE Wi-Fi. Safety was forefront with features such as lane departure warning, forward collision alert, and Cadillac's patented safety alert seat.
