Honda HR-V Real Gas Mileage: Pros
YearComment
2016 With EPA ratings of 28 mpg city and 35 mpg highway, the front-wheel-drive Honda HR-V nearly leads the class in fuel economy; that honor goes to the Mazda CX-3, with 29/35. Add all-wheel drive and they tie with 27/32. The Trax trails by a 2-3 mpg in the city and a single mpg on the highway. In my real-world driving, though, the Chevrolet's trip computer reported better numbers than the Honda's. Was it accurate? I don't know. But if it was, the Trax was a little more efficient in my suburban driving, 37 mpg vs. 35 mpg, and considerably more efficient in my highway driving, 40 vs. 34 mpg. Granted, that the tested Trax lacked all-wheel drive could explain the observed difference in suburban mpg, if not the larger one in highway mpg. It should also be noted that the Trax's fuel efficiency is more dependent on driving style. Employ a heavy foot, and the tiny four's turbo will shove far more fuel-air mixture into the cylinders. Since the EPA figures aren't terribly far apart and the trips computers cast some doubt on their accuracy, I've judged this category a tie. Drive either CUV casually, and you'll enjoy fuel economy well beyond the reach of most cars. see full Honda HR-V review

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
