2013 Cadillac ATS: Fuel Economy Update for December
January 6, 2014
In the month of December, our long-term 2013 Cadillac ATS spun an additional near-1,100 miles onto its odometer and consumed 49.5 gallons of 91-octane fuel. That equates to 22.1 miles per gallon for the month, which is almost bang-on its lifetime average of 22.2 mpg.
As of December, we've also cleared 20,000 miles in this entry-level luxury sport sedan, so we've got a comprehensive sample set for its fuel economy characteristics. We're trailing its EPA combined mpg by 1.8 mpg.
