bad fuel economy, I guess thats why 2006-2008 models do have a trip computer but the trip computer was not able. 2009 to present all have same trip computer that provides MPG,distance to empty and somewhat of an improved gas mileage. see full Mazda CX-7 review

With european fuel prices you can drain your wallet refuelling this car. However when you compare with other having 260 HP it is still not so bad see full Mazda CX-7 review

My Toyota Rav4 fuel economy was much better. Sometimes I have regrets getting 16MPG see full Mazda CX-7 review

The consumption is a bit to high but if you want power you must make some compromises. see full Mazda CX-7 review

Fuel economy not as good as many competitors in this class, combined with premium fuel requirements. see full Mazda CX-7 review

It is smaller yet gets the same gas mileage as the much larger and heavier Q7. see full Mazda CX-7 review

Averaged 15 MPG in the city. I would have expected closer to 20 MPG out of this vehicle. see full Mazda CX-7 review

Mazda RX-8 Real Gas Mileage: Cons

2009 4dr Coupe 232-horsepower 1.3L R2
6-speed manual RWD
One of the big downsides of the rotary is truly horrendous fuel economy. When the RX-8 first came out in the early 2000s, its mileage ratings of 16/22 city/highway mpg (stick shift) were just barely acceptable, but there days, with many crossovers hitting more than 30 mpg on the highway, those figures are truly atrocious, especially given respectable but certainly not neck-snapping power. Futhermore, it takes premium. If you're using the RX-8 as it commuter, fuel costs will add up quickly. In my predominantly around-town driving, I typically average between 16-17 mpg. My highest recorded average was 20 mpg on a highway trip at speeds around 75 mph. see full Mazda RX-8 review
2007 4dr Coupe 212-horsepower 1.3L R2
6-speed shiftable automatic RWD
The EPA numbers are way low compared with my real-world experience. The window sticker showed 18/25 and I have never seen less than 23 with my 40/60 city/highway commute. I think Mazda should develop a lean-burn economy cruise mode for this car. see full Mazda RX-8 review
2006 4dr Coupe 238-horsepower 1.3L R2

Lite bit to high consumption when I drive it in normal speed. On full woot its ok. see full Mazda RX-8 review

Worst fuel economy in its class. see full Mazda RX-8 review

Not that bad for what it is, but it seems to me that Mazda's Sky Active technology could help the city mileage. It just needs more R&D. see full Mazda RX-8 review

At 16 m.p.g. on premium grade these days it could be cheaper to take a taxi. see full Mazda RX-8 review
2004 4dr Coupe 238-horsepower 1.3L R2
6-speed manual RWD
For a small engine displacement and a relatively light vehicle weight, the gas mileage is weak. I usualy get around 19mpg, and that does not realy matter if I am doing all city or all highway driving. I think the real problem is in the sixth gear it isnt much different than fifth gear so it does not provide good fuel economy. see full Mazda RX-8 review
2004 4dr Coupe 238-horsepower 1.3L R2
6-speed manual RWD
For a car with a 1.9 liter engine I would have expected better than 16-19 MPG. Get your foot into it and the numbers fall drastically. Otherwise I loved that car. It just got too small with a newborn and a big dog. see full Mazda RX-8 review

I gets 20MPG no matter what I do. Running around 20. 1/2 highway 20. All the highway all day 25-26. I think that it could do better. see full Mazda RX-8 review
