You won't find best-in-class mileage in the 2014 Cadillac ATS, but with the turbo four it's pretty frugal for a sport sedan.

Expert Quotes:

2.5: 22/33 mpg 2.0T: 21/31 mpg V-6: 19/28 mpg AWD V-6: 18/26 mpg AWD 2.0T: 20/30 mpg

Another advantage for Cadillac is that the 2.5L and 3.6L use regular gas. The 2.0L prefers premium for full output but can also run on regular, Cadillac says.

GM has an embarrassing history of producing big-boned vehicles, packing more pounds than their similar-size competitors. To fight those fat genes, the ATS rides on an all-new rear-wheel-drive architecture rather than a cut-down CTS platform.

The ATS doesn't need this engine. Not for sales, not for marketing, and not for CAFE. The 2.0-liter turbo gets the exact same fuel economy and costs just $600 more than the 2.5-liter...
Motor Trend

The 2014 Cadillac ATS is one of the better models for fuel economy in this class of sport sedans, but it isn't the efficiency leader.

The base 2.5-liter four in the ATS is rated at 22/32 mpg, with the turbocharged 2.0-liter four earning the same ratings. At the other extreme, V-6 models earn 19 mpg city, 28 highway, or 18/26 with all-wheel drive.

Turbocharged 2.0T models stand in the middle, with ratings of 21/31 with rear-wheel drive, or 20/30 with all-wheel drive. Those numbers are a bit below those of the BMW 328i, which also includes stop-start technology, a potential fuel-saver in sluggish commuter traffic. There's also Audi's latest A4, with an eight-speed automatic--rated at 24/31 mpg.

A diesel version of the ATS is still a possibility for the U.S. market, but Cadillac hasn't yet announced a time frame for its introduction.

How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.
