EPA testing for the hotly anticipated 2013 Cadillac ATS has concluded, and the final numbers are in. The best numbers can be found with the sedan’s base naturally aspirated 2.5-liter inline-four engine with 202 horsepower and 191 lb-ft of torque combined with a six-speed automatic transmission. Those who commit to this powertrain will observe a return of a rated 22/33 mpg (city/highway), with a combined figure of 26 mpg.
For comparison, that highway number is parallel with the 2013 BMW 328i. However the 328i’s base 2.0L turbo provides a more adamant 240 horsepower, but requires pricey premium fuel to do so. The 211-horse Audi A4 base model returns 32 mpg on the highway at best, but that’s with the undesired front-wheel-drive setup and also requires premium. Other four-cylinder rivals, like the base 201-horse Mercedes-Benz C-Class returns 31 mpg on the highway.
Final numbers for the 2.0L turbo and range topping 3.6L V6 engine variants of the ATS are not yet on the fueleconomy.gov website at the time of this writing, but you can bet that when they are, we’ll share them with you all.
