2013 Cadillac ATS: Fuel Economy Update for November

December 04, 2013

2013 Cadillac ATS

The 2013 Cadillac ATS is about to leave our long-term road test fleet after a year of service. November saw over 2,000 miles added to the odometer, and although no new highs or lows were recorded, the needle did move up a bit thanks to some time on the open highway.

Lifetime mpg stayed pretty much the same, going from 22.1 mpg to 22.2. That's not terrible, but it's still 1.8 mpg (7.5 percent) lower than the EPA's 24 mpg combined estimate for the Cadillac. Clearly, depending on your driving style, a turbocharged four-cylinder engine is not necessarily the most frugal option, especially when you consider that the ATS's optional V6 engine is not far behind with a 22 mpg combined EPA fuel economy rating.

Worst Fill MPG: 12.6 mpg
Best Fill MPG: 30.6 mpg
Average Lifetime MPG: 22.6 mpg
EPA MPG Rating: 24 Combined (21 City/31 Highway)
Best Range: 432.9 miles
Current Odometer: 19,865 miles.

    Just as with your long term Ecoboost Explorer I would like to see how the ATS does if you have the exact same car with the V6. We know that the Turbo 4 beats the V6 on the EPA test cycle. But in real world driving, asking less of a bigger engine may yield better efficiency.
