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

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

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

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
 

TrueDelta Reviews the Real Gas Mileage of the Ford Mustang

Ford Mustang Real Gas Mileage: Cons
YearComment
2006 The performance of these cars is not without an obvious tradeoff. In EPA tests, the Mustang GT manages only 15 mpg city, but 25 mpg highway, with the manual transmission. With the optional six-speed automatic, the car can go a mile farther per gallon in the city. The Audi rates a little better in the city, but worse on the highway: 16/23. In my real-world suburban driving, the Mustang's trip computer most often reported averages in the 16-17 range. With a light foot I could nudge the average over 20, and even as high as 24, but what's the point of driving a Mustang GT like you would (or at least should) a Prius? On a 70-mph highway, with the big V8 spinning under 2,000 rpm in top gear, the trip computer reported a fairly impressive (for such a large, powerful engine in a fairly heavy car) 28 mpg. But if you want decent fuel economy in either car, you'll have to ditch the V8. The new EcoBoost four-cylinder achieves 22/31 with a manual transmission and 21/32 with the automatic. The Audi manages similar figures with a 220-horsepower 2.0T four-cylinder engine, but 17/26 with the manual and 18/28 with the automated dual-clutch transmission and the S5's supercharged V6. see full Ford Mustang review

For a 4.6L V8 using 87 octane, 20 city and 28 hwy is not bad. see full Ford Mustang review
2008 2dr Coupe 300-horsepower 4.6L V8

For a V8, I still get great fuel economy. I average 21mpg with combined city & highway, about 75% city. Only long highway trips, I average 27mpg at 70mph. see full Ford Mustang review
2007 2dr Coupe 300-horsepower 4.6L V8

Surprisingly, the V8 gets about 23-25 MPG highway driving IF you behave; better than my SUV. The Stang is my choice for my frequent 800+ miles trips once or twice per month. see full Ford Mustang review

2012 2dr Coupe 305-horsepower 3.7L V6
6-speed manual RWD
I was hoping for a bit better than the 24 I'm getting in commuting duty. Car still has less than 2000 miles, so it may improve w/ summer blend gas and a more broken in engine. If I could get 26 I'd be much happier, but I'm not counting on it see full Ford Mustang review

Premium fuel is expensive and mileage with a blown 5.4 is not stellar. I would not recommend this as a daily driver but it makes a hell of weekend and evening toy. see full Ford Mustang review
