TrueDelta Reviews the Real Gas Mileage of the Cadillac ATS

Cadillac ATS Real Gas Mileage: Cons
Year	Comment
	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

Pontiac G6 Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2009	4dr Sedan 164-horsepower 2.4L I4 6-speed shiftable automatic FWD	I opted to get the 4 cylinder 6 speed automatic because of the higher EPA rating and I have a fairly long commute to and from work. see full Pontiac G6 review
2007	4dr Sedan 169-horsepower 2.4L I4 4-speed automatic FWD	Getting 25 city miles see full Pontiac G6 review
2007	2dr Coupe 224-horsepower 3.5L V6 4-speed shiftable automatic FWD	Amazingly it gets 30+ on the highway. I usually drive in stop-and-go traffic but still get 20 mpg easily. see full Pontiac G6 review
2006	4dr Sedan 201-horsepower 3.5L V6 4-speed automatic FWD	Even with a 6 cylinder, and my overzealous driving, I regularly got 28-29 MPG. This is a mix of highway and city driving in a very hilly area. see full Pontiac G6 review

Pontiac G6 Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2008	4dr Sedan 219-horsepower 3.5L V6 4-speed automatic FWD	The V6 I drove had MPG ratings slightly worse than the 4-cyl models I was looking at. see full Pontiac G6 review
2007	2dr Hardtop conv. 217-horsepower 3.5L V6 4-speed shiftable automatic FWD	Not good enough. see full Pontiac G6 review
