Power figures mean nothing on paper. If anybody really wants to know how much horsepower and torque a vehicle delivers to the wheels, it needs to go through a dynamometer test. And it just so happens that Edmunds Inside Line did just that with the new Cadillac ATS 2.0T.
On paper, the Cadillac ATS’ turbocharged 2.0-liter inline four is GM-rated at 272 horsepower at 5,500 rpm and 260 pound-feet of torque between 1,500-5,500 rpm. Such relatively potent figures are achieved in no small thanks to direct injection and a twin-scroll turbo that spools up an impressive 20 psi of boost.
As an aside, Inside Line ran the ATS on “premium” 91-octane, not 93 or 94, for this test.
Finally strapped in, the ATS put down real-world numbers of 239 rear-wheel-horsepower and 252 lb-ft of torque at 4,000 RPM. Right where they should be when factoring in the power loss when transferred through the drivetrain to the road. Compared to a new BMW 328i, the real-world power figures are virtually identical. But the ATS is the lighter car, tipping the power-to-weight ratio in its favor.
Hopefully we will soon put the ATS through our own paces.Google+
