2013 Cadillac ATS to gets 2.0-liter turbo engine image

General Motors, on Wednesday said the upcoming 2013 Cadillac ATS will be available to the public with a new high-performance 2.0L turbocharged four-cylinder engine.

According to the automaker, the new turbocharged engine will produce an estimated 270 horsepower (201 kW).

Cadillac vice president of global marketing Don Butler said the new engine is the perfect match for the new ATS, which will be a refined performance luxury sedan.

The Cadillac-tuned four-cylinder unit employs several technologies including a twin-scroll turbocharger with air-to-air intercooler, direct injection, continuously variable valve timing and a two-stage variable-displacement oil pump with jet-spray piston cooling.

“The 2.0T has an exceptionally smooth and responsive power curve that will make the ATS nimble, quick and fun to drive,” Butler said.

Its 270 horsepower — 135 hp per liter — beats the energy density of V8 engines from brands such as BMW and Lexus, GM said. The car will also have an optional 3.6-liter V6 also available on the CTS, SRX and the upcoming XTS, Leone said.

The rear-wheel-drive ATS is Cadillac’s BMW 3-series fighter and is expected to be lighter than the 3-series. It will slot below the CTS in the Caddy portfolio and is expected to become the brand’s volume leader after it launches in the second half of 2012.
