2006	4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD	Good for a speedy V6 and a huge car. see full Pontiac Grand Prix review
2005	4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD	Thus far, I have averaged 23 and 26 mpg, both times have had roughly a 70 mile highway trip out of 200 miles. Overall, I find this to be acceptable. see full Pontiac Grand Prix review
2002	4dr Sedan 200-horsepower 3.8L V6 4-speed automatic FWD	HORRIBLE. 12-16mpg combined with both city and driving. see full Pontiac Grand Prix review
2002	4dr Sedan supercharged 240hp 3.8L V6 4-speed automatic FWD	BEFORE the switch to ethanol-mixed fuel, my supercharged V6 averaged 22mpg, getting 19 city and a staggering 34 highway. If you do long highway miles and want more comfort than any econo-box can offer, this is the car for you! see full Pontiac Grand Prix review

Pontiac Grand Prix Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2006	4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD	Great V8 exhaust note and instant acceleration comes at the cost of about 19 mpg in combined driving, versus 25 with my new car. That is a 30% increase. (the new car is 600 pounds lighter though...) see full Pontiac Grand Prix review
2005	4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD	17-19 mpg in the city. 25 If I drive on the intersate. 30 is possible at 60mph. Most of my driving is in the city. The beautiful v8 makes it impossible to stay out of the gas, but it can run on REG fuel. see full Pontiac Grand Prix review

What Our Members Are Saying about the Real Gas Mileage of the Infiniti EX

Infiniti EX Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
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
