2011 Infiniti M Real Gas Mileage: Pros

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

I get around 17 city/25 highway. Not impressive but this is not why you buy a car like this. see full Infiniti M review
