I was impressed by the milage I get on this vehicle: around 10.7L/100km in the city and around 9L/100km on the highway. Driving with A/C on adds at least one liter per 100km see full Toyota Sienna review

It is fair for a minivan, but the RAV4 gets significantly better mileage because it is built on the Camry chassis. see full Toyota Sienna 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

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

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

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
