Back in July, the EPA released fuel economy figures for the Cadillac ATS compact luxury sedan, showing it was capable of returning up to 33 mpg highway and 22 mpg city when equipped with the base 2.4-liter four-cylinder engine.

Now the EPA has released a new set of numbers on the Cadillac ATS, this time showing the fuel economy of the 3.6-liter V-6 equipped ATS.

In rear-wheel-drive form, the V-6 Cadillac will deliver 28 mpg highway and 19 mpg city, while all-wheel-drive will cost you one mpg in the city and two mpg on the highway.

Also just in are the fuel economy numbers for the 2.0-liter turbocharged four-cylinder Cadillac ATS, which looks to be the best choice for those who enjoy driving, but with an eye towards fuel economy.

According to the EPA, the 2.0-liter turbocharged Cadillac ATS will deliver 31 mpg on the highway and 21 mpg city, a drop of two mpg highway and one mpg around town compared to the base, 2.5-liter four-cylinder model.

While the Cadillac ATS’ fuel economy numbers aren’t exactly in hybrid range, they are a significant improvement over the previous entry-level Cadillac, the CTS.

In its most fuel-efficient 3.0-liter V-6 form, the larger Cadillac CTS sedan delivers just 27 mpg highway and 18 mpg city.

Although the BMW 3-Series still edges out comparable ATS models in fuel economy, the BMWs require premium fuel while the Cadillacs are happy with less-expensive regular unleaded.

As good as the four-cylinder ATS models sound, though, our preference would still be to wait for the promised clean diesel Cadillac ATS to hit the market.
