2013 2dr Coupe turbocharged 211hp 2.0L I4
8-speed shiftable automatic AWD		 Mileage seems to have leveled out at about 27 mpg with a 60/40 mix of highway and suburban driving. On longer trips, it has been as high as 30 mpg while driving a steady 75 mph. see full Audi A5 / S5 / RS5 review
2010 2dr Coupe turbocharged 211hp 2.0L I4
6-speed manual AWD		 Averaging 9L/100KM, without feeling too conservative. see full Audi A5 / S5 / RS5 review

2011 2dr Coupe 354-horsepower 4.2L V8
6-speed manual AWD		 I knew what gas mileage the S5 got long before I stepped onto the dealer lot. Still, I get 24 mpg on a full highway run. see full Audi A5 / S5 / RS5 review
2009 2dr Coupe turbocharged 170hp 2.0L I4 Diesel
6-speed manual AWD		 Fuel economy is fair when going for a long ride, the car is AWD and heavy. I did however expect a somewhat lower fuel consumption when driving short-distance. see full Audi A5 / S5 / RS5 review
2008 2dr Coupe 354-horsepower 4.2L V8
6-speed manual AWD		 It is not great, and if you have fun with the car, you will get less than 15MPG see full Audi A5 / S5 / RS5 review
2008 2dr Coupe 354-horsepower 4.2L V8
6-speed manual AWD		 drinks too fast when driving is more aggressive see full Audi A5 / S5 / RS5 review
2008 2dr Coupe 354-horsepower 4.2L V8
6-speed manual AWD		 Thirsty V8 coupled with a car that was born to be driven hard equals mid-teen MPG in mostly non-highway driving. see full Audi A5 / S5 / RS5 review

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

2012 4dr Sedan 330-horsepower 3.7L V6
7-speed shiftable automatic AWD		 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
2011 4dr Sedan 330-horsepower 3.7L V6
7-speed shiftable automatic RWD		 I get average about 22 MPG with 80% of highway driving, this is with baby footing of the car, in town and climbing the hill, the milage can drop to 18-19. see full Infiniti M review
2011 4dr Sedan 420-horsepower 5.6L V8
7-speed shiftable automatic AWD		 Fairly poor. 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
2008 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Gas mileage stinks. see full Infiniti M review

5-speed shiftable automatic RWD		 16.9 in city traffice 18.nothing on the highway...blah! see full Infiniti M review
2007 4dr Sedan 325-horsepower 4.5L V8
5-speed shiftable automatic RWD		 Averages about 18.5 mpg in mixed suburban/urban/freeway driving. Can get thirsty when you get on the gas, but duh... see full Infiniti M review
2007 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Large cars get poor milage. 18-20 mpg would like an option to trade some performance for added MPG. see full Infiniti M review
2006 4dr Sedan 280-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Often avergaed as low as 16mpg on a tank-full of gas. see full Infiniti M review
