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

TrueDelta Reviews the Real Gas Mileage of the Chevrolet Tahoe / Suburban

Chevrolet Tahoe / Suburban Real Gas Mileage: Pros
Year	Comment
2015	You didn't expect to see fuel economy among the reasons to buy a Tahoe, did you? Of course, fuel economy remains well below that for most smaller, lighter vehicles. But General Motors has substantially improved the SUV's efficiency by adding variable valve timing, direct injection (fuel is injected under high pressure directly into the cylinder, rather than into the manifold), and cylinder deactivation to the 5.3-liter V8. EPA ratings improved from 15 city, 21 highway to 16/23 with 2WD and 16/22 with 4WD. I observed averages as high as 21 in the suburbs and 26 on the highway, quite impressive for an 80-inch-wide, 74-inch-tall, three-ton vehicle. Transitions between V4 and V8 operation are not perceptible, with the engine usually in the former mode when not accelerating, even at highway speeds. Ford took a different approach to improving fuel economy, replacing its 5.4-liter V8 with a turbocharged 3.5-liter V6. The resulting EPA ratings of 15 mpg city and 20 mpg highway are better than before, but aren't as good as the Tahoe's. My trip computer averages were similarly two to three mpg shy of those observed in the Tahoe. see full Chevrolet Tahoe / Suburban review

2010	4dr SUV, ext. 320-horsepower 5.3L V8 6-speed shiftable automatic 4WD w/low range	I don't really have any complaints about this vehicle for our uses. But many people do buy them and don't use them for their intended purposes, and then complain about paying for gas. Well, it is a truck, after all. see full Chevrolet Tahoe / Suburban review
2010	4dr SUV, ext. 320-horsepower 5.3L V8 6-speed shiftable automatic 4WD w/low range	Even though its fuel economy is great for its size, it still uses a lot of gas see full Chevrolet Tahoe / Suburban review
2007	4dr SUV, ext. 320-horsepower 5.3L V8 4-speed automatic 4WD w/low range	In mostly local suburban areas we average 12 MPG. Highway only can reach 18 or 19 depending on load and hills. see full Chevrolet Tahoe / Suburban review
2007	4dr SUV 320-horsepower 5.3L V8 4-speed automatic 4WD w/low range	Fuel economy is not great, but it's not horrible either. Again, this is a full size SUV on a truck platform. How much can anyone truly complain when you know this going in? see full Chevrolet Tahoe / Suburban review

2005	4dr SUV 295-horsepower 5.3L V8 4-speed automatic 4WD w/low range	Poor gas mileage... but I knew this before purchasing it so this is not a problem for me. If gas prices scare you... then this is not the vehicle for you. see full Chevrolet Tahoe / Suburban review
2005	4dr SUV, ext. 295-horsepower 5.3L V8 4-speed automatic 4WD w/low range	At $4 a gallon and a 32 gallon gas tank, you feel it every time you fill up and if you drive a lot in the city, at 15 mpg, you will fill up often. The vehicle actually garners a respectable 21 mpg on the highway. see full Chevrolet Tahoe / Suburban review
2003	4dr SUV 285-horsepower 5.3L V8 4-speed automatic 4WD w/low range	The obvious. 16 MPG highway. Enough said. see full Chevrolet Tahoe / Suburban review
