2013 Cadillac ATS: Fuel Economy Update for December

January 6, 2014

2013 Cadillac ATS

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.

Note: Cars are sometimes refueled before their fuel tanks are nearly empty. As such, "best" and "worst" fuel economy entries above are not necessarily the result of an entire tank's worth of driving.
