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

Nissan Quest Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2014	4dr Minivan, ext. 260-horsepower 3.5L V6 CVT FWD	I was hoping for slightly better fuel economy, but for a 4500 lbs vehicle, I really shouldn't be complaining. In predominantly hilly suburban driving, I'm averaging a couple miles below the estimated city fuel economy number. On 100% hilly highway miles, I'm right about at or maybe 1 mpg above the estimated fuel economy. It would be nice to acheive better highway mpg, but I suppose that's the trade-off for having a torquey engine. You would think the CVT would improve things, and maybe in fact it is helping the poor fuel economy of the aging VQ engine design, but I also think the CVT transmission is a cost-cutting measure by Nissan. It would be nicer to have one of the 7 speed transmissions found in the Infiniti lineup. see full Nissan Quest review

2014	4dr Minivan, ext. 260-horsepower 3.5L V6 CVT FWD	Could be better, but then the van would have less power. Pick your poison. see full Nissan Quest review

2008	4dr Minivan, ext. 235-horsepower 3.5L V6 5-speed automatic FWD	All vans have pitiful fuel economy. The Quest is about average for the class. see full Nissan Quest review
