TrueDelta Reviews the Real Gas Mileage of the Cadillac ATS

Cadillac ATS Real Gas Mileage: Cons
YearComment
On paper, the ATS's engines meet or exceed competitors. Even the base 2.5-liter four-cylinder engine peaks at over 200 horsepower, while the 2.0-liter turbo kicks out 272 and the 3.6-liter V6 321. I found the base engine more satisfactory than most reviewers have. But the other two don't feel as strong as their power ratings suggest they ought to, and could also sound and feel more sophisticated and thrilling. They're all fairly good engines, but none of them is a great engine. Fuel economy falls short of the BMW. The 2.0T engine is EPA-rated 19 city, 30 highway with a manual transmission, 21/31 with an automatic. Step up to the V6, and the numbers fall to 18/28. Deduct a couple of highway mpg with AWD. The BMW's ratings are much higher. The 328i's 2.0T engine is rated 22/34 with a manual transmission, 23/33 with a six-speed automatic. The 335i's six-cylinder engine when paired with an eight-speed automatic transmission somehow manages the same EPA rating as the 328i's four-cylinder. In the real world it doesn't fare as well, though. The V6 in the Infiniti in conjunction with a seven-speed automatic transmission is about even with that in the Cadillac, 19/27. Pair it with a manual transmission and the numbers fall to 18/25, worst of the bunch. see full Cadillac ATS review

Cadillac DTS Real Gas Mileage: Pros
YearBody/PowertrainComment
2009 4dr Sedan 275-horsepower 4.6L V8
4-speed automatic FWD		 I bought this car almost specifically for my "road" car, for trips, but do occasionally use it around town. I don't know how the other reviewers are driving their cars but I get what I think is great mileage, mid-teens around town and 28-29mgh on trips/hwy at 75MPH. I do try to drive easy to enhance my mileage. see full Cadillac DTS review
2006 4dr Sedan 275-horsepower 4.6L V8
4-speed automatic FWD		 Great Milage for the level of comfort, 25 plus on trips. see full Cadillac DTS review
2006 4dr Sedan 275-horsepower 4.6L V8
4-speed automatic FWD		 Great on the highway. At 65 I get a consistant 25mpg. The city is an entirely different story. In stop and go city driving, the best I've ever gotten is 10mpg. The average is 8mpg. The EPA estimates 17 in the city. They are off their rocker. This car sucks gas in city driving. Stay away unless you have tons of money or own an oil refinery. see full Cadillac DTS review

2006 4dr Sedan 275-horsepower 4.6L V8
4-speed automatic FWD		 Terrible in the city. 8 mpg on average. At least it takes regular. see full Cadillac DTS review
2006 4dr Sedan 275-horsepower 4.6L V8
4-speed automatic FWD		 City gas mileage is pathetic. Since new I was lucky to get 10 mpg in the city, but in stop and go it's 8 mpg. When the car was newer, I took it to the dealer, and they checked everything out. I was told that it's a big V8. The Northstar engine is an embarrassment. see full Cadillac DTS review
