TrueDelta Reviews the Real Gas Mileage of the Mazda CX-5

Mazda CX-5 Real Gas Mileage: Pros
YearComment
2014 In a bid to broaden the appeal of its cars, Mazda added a focus on fuel economy to its traditional emphasis on handling. The 2013 CX-5 earned surprising EPA fuel economy ratings of 26 mpg city, 35 highway--but with a manual transmission and front-wheel-drive. Add AWD and a six-speed automatic transmission, and the ratings fell to a less lofty but still competitive 25/31. This, though, was with the wheezy 155-horsepower 2.0-liter engine. Certainly adding a half-liter of displacement (and 29 horsepower) must impact mpg. It does, but not much: fuel economy drops by a single mile per gallon, yielding 24/30. For those who'd like to trade the extra power for one mpg, the 2.0 continues to power the base "Sport" trim. I don't foresee many takers. The larger engine feels much stronger. At least as important, it doesn't sound nearly as weak and buzzy. But you won't find powertrain performance among the reasons to buy a CX-5 because the improvement merely makes the CX-5 competitive in this area. The CR-V and RAV4, among others, are about equally quick. Even with slightly lower EPA ratings the CX-5 still bests the 22/29 RAV4, especially in city/suburban driving. But there's a new segment champ. The 2014 Subaru Forester manages 24/32. see full Mazda CX-5 review

YearBody/PowertrainComment
2015 4dr SUV 184-horsepower 2.5L I4
6-speed shiftable automatic AWD		 My Mazda is the AWD model, and, I'm pleasantly surprised that it's bascially hitting its EPA numbesr so far. I've done 3 long trips, mostly interstate, running 70 - 75 Mph, and, average mileage is running 27.5 - 30 Mpg. see full Mazda CX-5 review
2014 4dr SUV 184-horsepower 2.5L I4
6-speed shiftable automatic AWD		 Hard to complain about averaging 27 mpg in an all wheel drive vehicle that is mostly surburban driven. see full Mazda CX-5 review
2014 4dr SUV 184-horsepower 2.5L I4
6-speed shiftable automatic FWD		 This SUV gets as good mileage as my father's Ford Escape Hybrid! Overall, I love that I am actually getting better MPG than my previous car, which was a 2009 Mazda 6. see full Mazda CX-5 review
2014 4dr SUV 184-horsepower 2.5L I4
6-speed shiftable automatic FWD		 The number two reason I chose this vehicle was for the gas mileage, which has so far exceeded my expectations. According to the information screen, I've been averaging between 29 and 30 mpg. see full Mazda CX-5 review
2014 4dr SUV 184-horsepower 2.5L I4
6-speed shiftable automatic AWD		 Fuel economy was the best in its class. see full Mazda CX-5 review
2013 4dr SUV 155-horsepower 2.0L I4
6-speed shiftable automatic AWD		 True to EPA estimates, 25 city/31 highway for the AWD AT. I've tracked about half of the miles I have driven on fuelly and get ~28mpg (mostly using the car to commute to work on state routes w/ 55 mph speed limits). see full Mazda CX-5 review

2013 4dr SUV 155-horsepower 2.0L I4
6-speed shiftable automatic FWD		 Outstanding, I am still meeting or beating the EPA standards for this vehicle with an automatic transmission. Over a 3500 mile road trip, the total (calculated) MPG was 31.3 for the entire trip, this was 2600 miles of interstate, and about 900 miles of city driving and touring. The speeds on the highway were 70-80 MPH for most of the interstate, so this seems to be above EPA speeds. Of course the mileage drops off above 70 mph, but cruising at 80 MPH in west Texas, the average (tank to tank) on the two tanks was 29.6 MPG. Most of this is because of the fact that the transmission is a help as well, the locking converter and six speeds allow for a good range of flexibility for the engine to run. see full Mazda CX-5 review
2013 4dr SUV 155-horsepower 2.0L I4
6-speed shiftable automatic AWD		 Being a "green" thinking person, I liked the fact that the Mazda has the best fuel economy in it's class, by a fair margin! It does deliver on it's claim: I get 30-33 on the highway, depending on average speed, even in the up and down terrain of Seattle highways, and average 20-23 in strictly city driving. Again, we have a lot of hills in Seattle, which have a big affect on fuel economy. The modest sized engine does work and rev a bit more than some of the others I drove, but it does just fine overall. IF you want a very fast 0-60 time get a BMW or Porsche SUV, but be prepared to pay the price at the pump!! see full Mazda CX-5 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
