DETROIT – A trio of power-dense engines, including two new four-cylinders and Cadillac’s renowned 3.6L V-6, gives the all-new 2013 ATS a strong balance of performance and efficiency. All three feature direct injection technology and lightweight components.

The engine lineup starts with a standard 2.5L four-cylinder; a 2.0L turbocharged four-cylinder and the V-6 are available. The four-cylinders are next-generation engines, with the 2.0T offered with a manual transmission – a choice that’s unavailable in some luxury cars.

Increased efficiency was a priority for the new four-cylinders. It was achieved partly through lower engine friction, which was reduced by up to 16 percent using new technologies such as a variable-displacement oil pump and, with the 2.5L, an actively controlled thermostat. Cadillac proprietary computational fluid dynamics (CFD) analysis techniques were used to develop an all-new combustion system with a higher compression ratio, which also helps boost efficiency.

The 2.5L is rated at an estimated 202 horsepower (151 kW) and 191 lb.-ft. of torque (258 Nm), while the 2.0T – the latest in a series of technologically advanced, high-output turbo engines – is estimated at 270 horsepower (201 kW) and 260 lb.-ft. of torque (353 Nm). The award-winning 3.6L V-6 is rated at an estimated 315 horsepower (235 kW) and 267 lb.-ft. of torque (362 Nm).

All of the engines feature direct injection and dual overhead camshafts with continuously variable valve timing, which help optimize power and efficiency, as well as reduce emissions. And all of the engines are matched with six-speed transmissions, including the Hydra-Matic 6L45 automatic with tap-shift control, and a six-speed manual available with the turbo engine.

“The ATS is all about balanced performance, and that’s exactly what the powertrain systems are designed to provide,” said Mike Anderson, global chief engineer for the Cadillac four-cylinder engines. “They are also refined, which enhances the driving experience with smoothness and predictability that inspires confidence as the revs climb.”
