Used 2019 Cadillac ATS Trims Comparison

Base and Luxury trims come with a turbocharged four-cylinder engine (272 horsepower, 295 pound-feet of torque) paired to an eight-speed automatic or a six-speed manual transmission and rear-wheel drive. All-wheel drive is optional, but only with the automatic transmission. Premium Luxury and Premium Performance models come with a 3.6-liter V6 engine (335 hp, 285 lb-ft) paired to an eight-speed automatic and rear-wheel drive. All-wheel drive is optional on Premium Luxury; Premium Performance trims are rear-wheel-drive only.

Key standard features for base trims include 18-inch alloy wheels, heated side mirrors, a rearview camera, keyless entry and ignition, power-adjustable front seats, and faux leather upholstery. Tech features include the revamped CUE interface with 8-inch touchscreen display, OnStar services with 4G LTE Wi-Fi hotspot, a Bose sound system, satellite radio, Apple CarPlay and Android Auto smartphone integration, wireless device charging, three USB ports and an auxiliary audio input.

The Luxury trim adds adaptive xenon headlights, front and rear parking sensors, leather upholstery, additional front seat power adjustments, heated front seats, a heated steering wheel and driver-seat memory settings. Options include an upgraded version of CUE bundled with navigation and a 110-volt household-style power outlet. The Safety and Security package adds driver assistance features such as forward collision alert, lane departure warning and lane keeping assist, blind-spot monitoring, rear cross-traffic alert, automatic high beams and rain-sensing wipers, and the Safety Alert Seat, which vibrates the driver seat to warn of lane drift, potential collisions or other hazards.

The Premium Luxury trim adds unique 18-inch wheels, a sunroof, adaptive high beams, rain-sensing wipers, and the Safety and Security package driver assistance features.

The Premium Performance trim includes all the previously mentioned features, plus high-performance tires, a sport-tuned suspension, adaptive suspension dampers, a limited-slip rear differential, a head-up display and a power-adjustable steering column.

Many standard features on the upper trims are optional on lower trims. The Driver Assist package, available on the Premium Luxury and Premium Performance trims, adds the head-up display, adaptive cruise control, and advanced safety technologies including forward and rearward collision mitigation and automatic emergency braking. Wireless device charging is also available as a stand-alone option.

The Track Performance package, available only on the Premium Performance trim, adds a heavy-duty engine-cooling fan and upgraded brake pads. All rear-wheel-drive Base, Luxury and Premium Luxury trims can add the V-Sport Performance Suspension Upgrade package, which adds 18-inch wheels, a sport-tuned suspension and high-performance tires.

Cadillac's Teen Driver features are also standard. They allow owners to limit certain functions when younger drivers are behind the wheel, such as muting audio until front seat occupants fasten seat belts or preventing drivers from disabling safety systems such as traction control. Teen Driver can also capture data — including distance driven, maximum speed, overspeed warnings and hard braking events — and generate a "report card" for owners to review with younger drivers.
