2013 4dr SUV 325-horsepower 3.7L V6
7-speed shiftable automatic AWD		 Could be better by today's standards see full Infiniti EX review
2010 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic AWD		 love the V6 power but the EPA MPG is worrisome see full Infiniti EX review
2010 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic RWD		 OK This is NOT a car to buy if MPG is important although I am getting over 23 MPG avg. It is a POWERFUL car with a great drive train ready like a race horse at the gate to giddy up and it does when you need it on premium recommended fuel....in spades. I don't drive enough to care about fuel economy all that much. Not an econobox. see full Infiniti EX review
2009 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic AWD		 17MPG in the city is a little disappointing for a vehicle with such finesse and reputation. I would guess Infiniti would cater to the masses with styling, performance and a little more economy. Not asking for miracles but I'm sure they could squeeze out 3 or 4 more MPG with the same 3.5L V6 see full Infiniti EX review
2008 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Uses premium fuel. see full Infiniti EX review
2008 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic RWD		 I average about 20 miles per gallon on premium fuel - with a mix of street and highway driving. I typically get 16 mpg in the city and 24 on the highway. Some of this is attributable to the 5 speed transmission on the car, which favors acceleration to economy. I imagine the 7 speed transmission should help the car get better highway economy. see full Infiniti EX review
2008 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Expensive to keep fuelled given poor gas mileage and costs of premium fuel. Number 1 reason I am thinking of switching to another car. see full Infiniti EX review
2008 4dr SUV 297-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Slightly low if driving mostly city. see full Infiniti EX review

YearBody/PowertrainComment
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
Audi A5 / S5 / RS5 Real Gas Mileage: Cons
YearBody/PowertrainComment
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
