What Our Members Are Saying about the Real Mazda RX-8 MPG

Mazda RX-8 Fuel Economy: Cons
YearBody/PowertrainComment
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.
2006 4dr Coupe 238-horsepower 1.3L R2
6-speed manual RWD		 Lite bit to high consumption when I drive it in normal speed. On full woot its ok.
2005 4dr Coupe 238-horsepower 1.3L R2
6-speed manual RWD		 Worst fuel economy in its class.
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.
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.
2004 4dr Coupe 238-horsepower 1.3L R2
6-speed manual RWD		 16-18MPG city, 24MPG highway
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.
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.
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.
