2013 Cadillac ATS: Fuel Economy Update for September

October 3, 2013

2013 Cadillac ATS

After last month's 3,000 miles, September was relatively quiet for our 2013 Cadillac ATS. We added fewer than half that, about 1,300 miles. For those miles, we averaged 20.7 mpg. That's a few mpg below the EPA's 24 mpg estimate for combined driving.

In terms of a lifetime average, we're still below that EPA combined average as well. After our nearly 16,000 miles, we're averaging 21.9 mpg.

Worst Fill MPG: 12.6
Best Fill MPG: 30.6
Average Lifetime MPG: 21.9
EPA MPG Rating: 24 Combined (21 City/31 Highway)
Best Range: 432 miles
Current Odometer: 15,938 miles

    How about you put all the fuel economy numbers on 1 post? I don't even bother looking at any of them when there are so many. Also you have had the Corvette for 2 day's and no posts, I come here less and less every week.

    Not too good. This car with this engine should be at that 24 mpg combined number. By all accounts the ATS is besting the 3 series in terms of driving dynamics. But quietly, BMW has been increasing its fuel efficiency at an impressive rate. I think that BMW is guessing that the next frontier for bragging rights among luxury car buyers is not simply acceleration or slalom times. People are really paying attention to efficiency. It will be a shame if just as Cadillac falls way behind BMW in terms of fuel efficiency just as they catch up in terms of everything else.

    clearly, there is little to no benefit of the turbo 4 over the V6.

    The only way a turbo-4 is going to achieve "real world" efficiency gains is if it is driven gingerly at all times. As soon as the motor is asked to produce more than about 50% of it's performance, any efficiency gains are lost. Long term test vehicles driven by automotive journalists are very likely driven more aggressively than by true owners. I own a Kia with a 2.0 liter turbocharged motor. Very efficient on long steady highway cruises but around town it never gets the EPA city rating. Give me my V6!

    Needs an 8speed tranny to improve the mileage.

    I just test drove one of these today, and I can see why your mileage isn't that great... DAMN, this car has some punch when you slam down the pedal! It's crazy addicting! I WANT ONE!
