It was announced some time ago that the 2015 Cadillac ATS Coupe would feature 272 horsepower and 295 pound-feet of torque from its base 2.0L turbocharged engine, giving it an edge over the 2014 ATS Sedan in the power department, which has only 260 lb-ft. Not so with the 2015 model, as the 2015 ATS Sedan powered by the 2.0-liter turbocharged four-cylinder engine joins its two-door brother with an equal gain in twisting force.
Engine calibration resulting in increased boost pressure allowed for the additional torque, and at 136 horsepower per liter, the 2.0-liter turbo is one of the most power-dense engines in production. A broad torque band (90% of peak torque from 2100 rpm to 3000 rpm and full torque from 3000 rpm to 4600 rpm) is supported by high boost levels in the speed range.
“The ATS is already the most agile vehicle in its respective classes,” said David Masch, the Cadillac ATS’ chief engineer. “The additional torque works to further improve on an already dynamic vehicle.”
Also new to the 2015 ATS Coupe and Sedan are Lane Change Alert and Lane Keep Assist. Drivers are alerted to vehicles in and approaching their blind spots by flashing symbol lights on the mirrors once a turn signal has been activated. When traveling faster than 37 mph, the ATS uses a camera to detect if the vehicle leaves its lane unintentionally, and can nudge the power steering to correct.
