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

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

2013	4dr Sedan 148-horsepower 2.0L H4 5-speed manual AWD	Wow, this is what I said after 2 days with the vehicle, winter driving, and its cold winter here. I averaged 7.6 l/100km, mixed city and highway driving, at -20 celsius, through snow most time of these 2 days. Very impressive for awd vehicle! see full Subaru Impreza / Outback Sport review
2013	4dr Hatch 148-horsepower 2.0L H4 6-speed shiftable CVT AWD	It takes a while for the engine & drivetrain to break in, but when they do you will start to see some very impressive numbers on the ODO. I'm at ~2600 miles right now and averaging 29-30 mpg between 50% open freeway cruising, 25% freeway traffic, 25% city driving. see full Subaru Impreza / Outback Sport review

2004	4dr Wagon 165-horsepower 2.5L H4 4-speed automatic AWD	I get 23-26mpg around town, 28-30 highway, which I consider very very good for an AWD car. I get same fuel economy as many non AWD cars. see full Subaru Impreza / Outback Sport review

2012	4dr Hatch 148-horsepower 2.0L H4 CVT AWD	The fuel economy isn't as high expected. I get about 28 mpg. I should probably stop driving like I stole it when the kids are out of the car. see full Subaru Impreza / Outback Sport review
2010	4dr Sedan turbocharged 265hp 2.5L H4 5-speed manual AWD	Not really dislike, I didnt expect civic like mpg. Around town mileage suffers, but on the highways the car cruises quite easily. You can expect ~25mpg on average combined (with no led food). Impressive for the hp and AWD. see full Subaru Impreza / Outback Sport review
2010	4dr Hatch 170-horsepower 2.5L H4 5-speed manual AWD	Really crappy, especially for a 2.5L 4 cylinder engine. 22 MPG average. 18 city, 27 highway is what I got. see full Subaru Impreza / Outback Sport review

2008	4dr Sedan 170-horsepower 2.5L H4 4-speed automatic AWD	Pathetic for a compact sedan at <28 mpg highway. The AWD system must be a huge fuel sink. see full Subaru Impreza / Outback Sport review
2008	4dr Hatch 170-horsepower 2.5L H4 4-speed shiftable automatic AWD	For such a small car with NA 170hp engine the economy is rather poor ~24mpg. see full Subaru Impreza / Outback Sport review
2007	4dr Wagon turbocharged 224hp 2.5L H4 5-speed manual AWD	For a car of that size, the fuel economy is dismal. I get about 19 in the city, which is where most of my driving is done. That is marginally better than any SUV. see full Subaru Impreza / Outback Sport review
