2013 Cadillac ATS will get all-new 2.0-liter turbo engine
General Motors announced this week preliminary information about an all-new 4-cylinder, turbocharged, high performance 2.0-liter engine which will first power the 2013 Cadillac ATS, a car that we shall see in January next year at the Detroit Motor Show.
This direct-injection engine is capable of generating 270 hp (273 PS / 201 kW) and a maximum torque of 260 lb.-ft (353 Nm). Since it has a power-density of 135 hp (136 PS / 100 kW) / liter, this would have to be one of the top performers in this segment. To show how great this engine is, GM has compared it with the 2.0-liter turbo unit from the Audi A4 which produces 105.5 hp / liter, the V8 engine from the Lexus IF that churns 83.2 hp per liter, the V8 from the BMW M3 that develops 103.5 hp per liter, and the 1.8-liter power plant from the Mercedes-Benz C250 that generates 111.6 hp per liter.
This engine has a low-friction design and 90% of the peak torque is available starting at only 1,500 rpm, allowing the 2013 Cadillac ATS to have a good thrust at low and high speeds. Some of the other highlights of the power unit include: twin-scroll turbocharger with air-to-air intercooler, direct-injection, twin-cam, four valves per cylinder with continuously variable valve timing, two-stage variable displacement oil pump that has jet-spray piston cooling and forged-steel crankshaft which features a modular balance shaft system.
The upcoming 2013 ATS will also be available with two other engines, a 4-cylinder 2.5-liter unit and a beefier V6 3.6-liter power unit.
