On a recent trip from Charlottetown, PE, Canada to Halifax, NS my car averaged 35 miles per US gallon, or over 730km per tank of fuel. As a Merchandiser, my job requires a lot of city Driving and I average 600km per tank of gas see full Mazda Protege review

The car does get excellent fuel economy- IF you can keep your foot out of it. I rarely succeed in that endeavor- the car is just too much fun to drive, the embodiment of "driving a slow car, fast." see full Mazda Protege review

Not too bad, the roof rack hurts it a bit. gets a solid 22-25 driving 70-75 on highway. Does get 30mpg at 60 mph, but that speed will get you killed on California interstates. see full Mazda Protege review

Suburban fuel economy is acceptable, at nearly 30 mpg. But on the highway, with the engine spinning well over 3,000 rpm, fuel economy also struggles to crack 30. Many much larger, much more powerful cars achieve better highway fuel economy. Some owners have fitted the fifth gear from the related transmission in the Mazda6 to get more of an overdrive. see full Mazda Protege review

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

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

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
