Engines and Transmissions

A powerful 2.0L turbocharged four-cylinder engine is standard on ATS Turbo and ATS Turbo Luxury sedan and coupe models. ATS Premium Luxury and ATS Premium Performance sedan and coupe models are powered by Cadillac’s award-winning 3.6L V6 engine.

The 2.0L Turbo delivers 90 percent of its peak torque from 2,100 rpm to 3,000 rpm and the full 295 lb-ft of peak torque (400 Nm) from 3,000 to 4,600 rpm. The broad torque band is supported by up to 18 psi (1.26 bar) of boost, which is designed to give the lightweight Cadillac ATS an exhilarating feeling of immediate power on demand.

With an SAE-certified output of 335 horsepower (250 kW) and 285 lb-ft of torque (386Nm), the ATS’s 3.6L V-6 engine balance performance and efficiency with technologies including Active Fuel Management (cylinder deactivation), which temporarily deactivates two the cylinders in light-load driving conditions to enhance fuel efficiency.

Both engines optimize power and efficiency with direct injection, dual overhead camshafts with continuously variable valve timing and automatic Stop/Start. The Stop/Start system shuts down the engine in certain driving conditions such as stop-and-go city driving to reduce fuel consumption, automatically restarting when the driver takes his or her foot off the brake pedal.

A paddle-shift eight-speed automatic transmission that drives performance is standard with all Cadillac ATS engines. A six-speed manual transmission is available with the ATS Turbo — a choice unavailable with many luxury competitors.

The eight-speed automatic transmission features four simple gear sets for optimal efficiency and five clutches (two brake clutches and three rotating clutches), creative packaging that enables them to fit the same space as a six-speed automatic.

World-class shift time quickness and responsiveness with the eight-speed are accomplished with a Gen II controls system, which works with variable force solenoid technology and three internal speed sensors. The transmission controller is mounted externally and its processor executes hundreds of calculations and commands as fast as every 6.25 milliseconds.

Additionally, friction-reducing design features, including synthetic fluid, and lower spin losses via a power flow that uses only two open clutches contribute further to efficiency. The torque converter design is also specific to each transmission.
