GM announces 270 horsepower turbo 4-cylinder for Cadillac ATS
This new 2.0L turbocharged 4-cylinder builds on past turbocharging programs and the result is an engine that offers 2013 Cadillac ATS drivers a whopping 135hp per liter – making it one of the most powerful cars in the class by that measure. "This engine is the perfect match for the new ATS, which will be a refined performance luxury sedan," said Don Butler, Cadillac vice president of Global Marketing. "The 2.0T has an exceptionally smooth and responsive power curve that will make the ATS nimble, quick and fun to drive."
General Motors reached these impressive measures with the new 2.0L turbo engine through a specially tuned application of the company’s direct injection system and variable valve timing combined with a twin scroll turbocharged that shoves 20 pounds per square inch of air into the engine to produce the 270hp output. More impressively, 90% of the turbo 4-cylinder’s 260lb-ft of torque is available from 1,500, revving all the way to 5,800rpm before running out of engine.
