2013 Cadillac ATS receives EPA fuel economy ratings [Update]
The 2013 Cadillac ATS will return up to 33 mpg on the highway.
After initially posting figures only for the 2.5-liter model, the EPA has finally released official fuel economy numbers for (nearly) all of the 2013 Cadillac ATS' powertrain combinations.
The range-topping 3.6-liter V6, which produces 321 horsepower and pairs exclusively with a six-speed automatic transmission, is rated at 19/28 city/highway mpg with RWD and 18/26 mpg with AWD. The volume engine, a 2.0-liter turbocharged four-cylinder with 272 horsepower, returns 21/31 mpg in RWD form and 20/30 mpg with AWD when equipped with the automatic.
The EPA still hasn't ruled on the enthusiast-focused 2.0-liter turbo/six-speed manual configuraiton, but Cadillac predicts that it will be good for 22/32 mpg.
The fuel-economy champ of the ATS lineup, the 2.5-liter four-cylinder model, is rated at 22/33 mpg. The naturally aspirated four makes 202 ponies and can only be had with the automatic.
Thanks to a trim curb weight of 3,315 pounds, the 2.5-liter ATS ranks as one of the most fuel efficient vehicles in its segment. The 2012 Mercedes-Benz C250 sedan returns 21/31mpg while the Audi A4 manages 24/31mpg on the EPA's test loop. The ATS' main rival - the BMW 3-Series - is rated at 23/33 mpg in four-cylinder, automatic-equipped 328i form.
Production of the ATS began in July, and the sedan officially went on sale earlier this month with a base price of $33,990 (including destination).
