2016 Cadillac ATS

The ATS is Cadillac's first shot at competing directly with the world's best entry-level luxury sedans - including the benchmark BMW 3-Series - in terms of size, handling, technology and refinement. Riding on GM's new rear/all-wheel-drive Alpha platform, the ATS was optimized at the demanding Nurburgring track in Germany and has the responsive driving dynamics to prove it.

Recent Changes
The ATS received a handful of updates for the most recent model year, including the availability of an updated 3.6L V6 with active fuel management, auto start/stop technology on turbocharged models, an all-new, eight-speed transmission on non-turbo models, an updated CUE suite with Apple CarPlay, and a new safety package.

Stylistically, the ATS exhibits a softer, somewhat conservative take on Cadillac's once-edgy Art & Science design language. Narrow, elongated headlights that extend halfway down the sides of the hood are a distinctive touch, while a rising beltline adds a hint of athleticism.

The ATS is smaller than Cadillac's CTS sedan and nearly identical to the 3-Series in all major dimensions. Cadillac says that the ATS undercuts its competitors with a curb weight as low as 3,400 pounds (for base models), which was achieved by employing lightweight materials such as an aluminum hood, magnesium engine mount brackets and natural-fiber door trim panels.

The low mass pays dividends in terms of handling, which is also aided by a suspension setup composed of a multi-link double-pivot MacPherson-strut with a direct-acting stabilizer bar up front with a five-link setup at the rear. Performance is further augmented by an optional sports suspension with GM's impressive Magnetic Ride Control system, which can adjust the dampers in the blink of an eye to prevent body roll during hard corners or keep passengers comfortable while cruising.

Inside, the ATS emulates the CTS with a similarly sharp-edged design and extensive use of premium materials, including stitched surfaces on the dashboard and doors. Befitting its performance-oriented character, the ATS is available with carbon fiber interior trim, while real wood is another trim option.

The ATS is also offered with Cadillac's new CUE infotainment system, which controls navigation, communication and vehicle settings through an eight-inch advanced tactile-feedback touch-screen designed to emulate the look and feel of a smartphone. The system replaces most of the conventional buttons and knobs on the dashboard, and can reportedly be configured for technophiles, troglodytes and everyone in between. It also supports Apple's CarPlay smartphone integration system.

Powertrain Lineup
The ATS is available with the buyer's choice of three different engines, automatic or manual gearboxes and rear- or all-wheel-drive.

The base motor is a 2.5-liter four-cylinder that produces 202 horsepower and 190 lb-ft of torque. Available exclusively with an eight-speed automatic transmission and RWD, this engine returns 21/33 city/highway mpg.

Those looking for a mix of performance and fuel economy can opt for the mid-level 2.0-liter turbocharged four-cylinder, which serves up a healthy 272 horsepower and 295 lb-ft of torque. A six-speed manual is available for enthusiasts; so equipped, the 2.0-liter ATS returns 19/30 mpg. With the standard six-speed automatic, the motor returns 21/30 mpg with RWD or 20/28 mpg with the optional AWD system. This engine also features an auto stop/start function.

The range-topping engine has been updated for the latest model year. It's a 3.6-liter V6 that pumps out 333 horsepower and 285 lb-ft of torque. Only the eight-speed automatic gearbox can be had with the big six. This engine's fuel economy has not yet been EPA certified in either RWD or AWD configurations.

All engines can run on regular fuel, although Cadillac recommends premium for the turbo.

Trim Level Breakdown
The ATS can be had in a number of trim levels based on engine choice - the 2.5-liter motor is the default choice in Standard and Luxury trims, the 2.0-liter turbo can be spec'd in Standard, Luxury, Performance and Premium trims, and the 3.6L is avaialble in Luxury, Performance or Premium form.
