2013 Cadillac ATS: Fuel Economy Update for August

September 5, 2013

2013 Cadillac ATS

Our long-term 2013 Cadillac ATS saw quite a bit of action in August, adding nearly 3,000 miles to its odometer. After all those miles, lifetime fuel economy on our four-cylinder ATS stands at 22 mpg. This is, of course, 2 mpg short of the ATS 2.0T's combined EPA estimate. And if you've read Dan Edmunds' piece, "MPG Is Stupid," you know we're actually 8.3 percent off the pace.

While 8.3 percent isn't massive, things could be better. We have yet to hit the highway EPA estimate of 31 mpg in the Cadillac ATS. This past month, we had a record low of 12.6 mpg. I attribute the bad tank to some record-high temperatures and loading the ATS down with cargo to help a friend move. Despite this tank, our lifetime average for the ATS actually went up slightly, improving from 21.6 mpg in July.

Worst Fill MPG: 12.6 mpg
Best Fill MPG: 28.5 mpg
Average Lifetime MPG: 22.0 mpg
EPA MPG Rating: 24 Combined (21 City / 31 Highway)
Best Range: 432.9 miles
Current Odometer: 14,778 miles.
