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
