Fiat 500 Real Gas Mileage: Pros
YearBody/PowertrainComment
2015 2dr Hatch 101-horsepower 1.4L I4
5-speed manual FWD		 Good fuel economy with manual, but most compacts with auto are more frugal and much faster. see full Fiat 500 review
2015 2dr Hatch turbocharged 160hp 1.4L I4
5-speed manual FWD		 Fuel economy on 500s in general is excellent. I have found that the engines are really "tight" when brand new. On my first tank (50/50 city/highway) with the Abarth, I couldn't crack 30 MPG. At 4000 miles, I'm now at 38.8 mpg on the exact same route. The other Fiats I have owned exhibited the exact same behavior. As with the other 500s, I expect a further minor improvement in fuel economy, leveling out at about 5000 miles. see full Fiat 500 review
2014 2dr Convertible turbocharged 160hp 1.4L I4
5-speed manual FWD		 Considering it's got a big turbo that I can't help but make use of, I still seem to be averaging an odometer-confirmed 30mpg in mixed driving (high speed mountain freeways and congested city). I've had a few flatter road trips creep into 33mpg territory, and a long run of backroad-strafing dip down to 27. Overall, I'm happy with the economy considering just how fun to drive the car really is. see full Fiat 500 review
2013 2dr Hatch 101-horsepower 1.4L I4
6-speed shiftable automatic FWD		 With the Pop Auto trans we are getting 31 mpg avg. see full Fiat 500 review
2013 2dr Hatch 101-horsepower 1.4L I4
5-speed manual FWD		 Cheap to Keep! My Fiat 500 Pop with Manual transmission gets 42.5 mpg recorded on my notebook computer over the first two years of ownership. This includes the first day I got the car from the dealership until I stopped bothering to keep records since the on-board computer mpg calculations are with 5/10ths of my own record keeping. To keep this in perspective, I do little straight highway driving. I prefer using back rural roads when possible (highway driving is SO boring!). A couple times a week I drive 20 miles each way and the trip contains 16 full stops at stop sighs or intersections. The terrain is rolling up and down and on these trips without trying the car gets 42 to 43 mpg. If I work at getting the best mileage, I've gotten over 50mpg. True city stop and go traffic hurts and I rarely get over 31mpg until the road opens up a bit. Pure highway driving at 70 mph brings about 40 mpg and slightly less if I hold near 80 mph (maybe 38 mpg but don't do this often enough to get a real average). My wife drives a Nissan Sentra with the Variable Ratio transmission and drven carefully on the highway it can get 36-37 mpg from a bigger and more comfortalbe car. Yet while the Nissan is a very good automobile, it isn't like my 500 for just fun and smiles.The see full Fiat 500 review
2013 2dr Convertible 101-horsepower 1.4L I4
6-speed shiftable automatic FWD		 My auto trans Fiat 500c gets 35mpg average over the first year of ownership (done on my computer spreadsheet, not from my head or the car trip compute). I do not do a lot of true city driving (I live in a small town of less than 10,000 folks) nor a lot of true highway driving at high speeds (75-80mph). But when I do go on two or three hour dives (one way) the car does better getting 40mpg. My normal drive one way is 19 to 20 miles with 16 complete stops required (yes, I make full stops not "roll-thru"). On these drives the car computer shows an average of 34-36mpg and that proves to be pretty accurate so I stopped working mpg on a separate spreadsheet. It does take premium fuel so there are better cars for pure mpg than this. But you do get some style for the extra cost. see full Fiat 500 review
2013 2dr Hatch turbocharged 160hp 1.4L I4
5-speed manual FWD		 On a longer freeway trip, I averaged about 35 mpg. In most mixed driving (my daily commute is very short, only about 2 miles) I average about 27 mpg. Not bad, especially considering I tend to, um, make the most of that exhaust note. see full Fiat 500 review
2013 2dr Hatch 101-horsepower 1.4L I4
5-speed manual FWD		 Fuel economy. I can wring the little thing around all day, up and down hills, revving high etc, and I still have averaged 36mpg over the first 4500 miles. If I drove in a flatland area (Florida) and kept my foot off the gas so much, I could easily get 40+ mpg. see full Fiat 500 review
2013 2dr Hatch 101-horsepower 1.4L I4
5-speed manual FWD		 Fuel economy has been excellent with a low of 36.9 and a high of 42.1 MPG with mostly highway driving. Fiat specs the car for 91 octane fuel, although 87 is permitted. I use 93. I have tried most of the major brands and have seen no difference in economy, with the exception of Mobil, which routinely returns a 2MPG improvement over other brands. Not sure why- I had a Hyundai that did the same on BP, so please don't think I am pushing a preference, as I have none, The car is also very sensitive to tire pressure in relation to fuel economy. The factory recommends 38 PSI, 34 rear. I am running 40/36 with no difference in ride quality but slightly improved economy. see full Fiat 500 review
2012 2dr Hatch 101-horsepower 1.4L I4
6-speed shiftable automatic FWD		 I'm usually in the 32-35 mpg range with a mixture of city and highway driving. I have to push it a bit to keep up with traffic (101 hp engine) which is probably why it's a bit lower. Fill ups are rarely more than $30. see full Fiat 500 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
