More fuel mileage numbers for the Cadillac ATS are in, with the current range-topping 321-horse, 275 lb-ft 3.6L LFX V6-powered model returning an EPA-estimated 19 miles per gallon in the city and 28 on the highway, whilst starting at $42,090. The numbers appear underwhelming, but we should note that the 321 hp engine requires only regular 87 octane, and can be substituted with E85 — whereas its German competitors require premium gasoline.
For those looking at the all-wheel-drive model, the numbers slightly decrease to a 18 city/26 highway mpg rating while commanding a $2,000 premium. Both utilize a six-speed automatic transmission, as there is currently no manual transmission offered for the V6 ATS.
As a refresher, the base ATS with a 202 hp 2.5L Ecotec returns 22 mpg city and 33 highway. The 270 hp turbocharged model still awaits its EPA numbers.
Meanwhile, the $43,695 2013 BMW 335i and its turbocharged 3.0-liter I-6 is EPA-rated at 23 city/33 highway mpg. The engine does require the more expensive premium-grade gasoline, but those modern eight-speed automatic transmissions really seem to make a difference.Google+
