What Our Members Are Saying about the Real Gas Mileage of the 2004 Mazda RX-8

2004 Mazda RX-8 Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2005	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	Worst fuel economy in its class. see full Mazda RX-8 review
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	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
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	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	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
2004	4dr Coupe 238-horsepower 1.3L R2 6-speed manual RWD	16-18MPG city, 24MPG highway 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

Mazda RX-8 Gas Mileage (MPG)

Unlike other fuel economy surveys, TrueDelta's Real-World Gas Mileage Survey includes questions about how and where a car was driven. So you can get an idea of the Mazda RX-8's real-world MPG based on how and where you drive a car.

I like words better than numbers.
