Infiniti Q50 Real Gas Mileage: Cons
Year	Comment
	With EPA ratings of 19 mpg city and 27 mpg highway, the Q50 AWD falls short of the BMW's scores (21/31). But it's on par (or better) compared to the others. If fuel economy is a priority then the Q50 Hybrid is the way to go, with EPA ratings of 29/36 with rear-wheel-drive and 28/34 with all-wheel-drive. Opt for the S variant and these numbers take a bit of a hit, to 28/34 with RWD and 27/31 with AWD. BMW also offers a hybrid, but not with AWD, and it's not as fuel efficient (25/33). The Q50S Hybrid costs another $1,850. Quite reasonable, as it's not only more efficient, but also torquier and quicker. More of an issue: it weighs more, which likely impacts handling, and the battery pack reduces trunk volume to a class-trailing 9.4 cubic feet. see full Infiniti Q50 review
