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

Mazda RX-8 Real Gas Mileage: Cons
YearBody/PowertrainComment
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
6-speed manual RWD		 Lite bit to high consumption when I drive it in normal speed. On full woot its ok. see full Mazda RX-8 review
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		 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
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

2012 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic FWD		 I purchased this vehicle in April of 2012,new with less than 25 miles showing. My wife drives this car to work each day, round trip is approx 30 miles. She is averaging 17 mpg, but on trips I drive and can average 22-23 mpg. I usually cruise the interstate at 70-80 mph. and I do use the cruise control. The mpg will vary but I have seen a high of 25 and a low of 21. Overall very pleased with the ride and comfort, when traveling there are usually 3 adults and luggage. see full GMC Acadia review

2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 Love the fuel economy of the Acadia... we get 19-22mpg in town.. and 22-26mpg on the interstate. Vehicle speed really affects the mileage attained. We get the best mileage at 55-60mph... it really drops when doing 70-80mph.. see full GMC Acadia review
2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic FWD		 For a vehicle the size, it get decent fuel economy. Driving the speedlimit sure does help, pushing that much air at 80 really hurts fuel economy. see full GMC Acadia review

2008 4dr SUV 275-horsepower 3.6L V6
6-speed shiftable automatic AWD		 Even with conservative driving over long distance, was not able to get close to EPA MPG. In order to get those numbers I have to depart too far from my normal driving habits - wont happen easily, no fun. Especially when the Acadia is so willing to sprint. see full GMC Acadia review
