2011	4dr Sedan 330-horsepower 3.7L V6 7-speed shiftable automatic AWD	Fuel economy is abysmal around town. I guess that's the price you pay for going grocery shopping with over 300 HP. However, on the highway it's very possible to exceed the EPA mileage number. see full Infiniti M review
2006	4dr Sedan 335-horsepower 4.5L V8 5-speed shiftable automatic RWD	V8 power--it's a gas guzzler and could've used an extra 1 or 2 speeds more since it revs so high at highway speeds. see full Infiniti M review
2006	4dr Sedan 335-horsepower 4.5L V8 5-speed shiftable automatic RWD	78,000 miles primarily city driving and rarely use AC-16.9 mpg. 4.5 L V8 great power train with RWD-great fun to drive. see full Infiniti M review

2008	4dr Sedan 275-horsepower 3.5L V6 5-speed shiftable automatic RWD	needs a 6th gear, since there is too much revving in 5th gear while cruising. they put a 6th gear in the 2009 version see full Infiniti M review
