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

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

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

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

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

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
 

TrueDelta Reviews the Real Gas Mileage of the Mazda MX-5 Miata

Mazda MX-5 Miata Real Gas Mileage: Pros
YearComment
2016 Nothing has improved more with the Mazda MX-5 Miata's latest redesign than its fuel economy. The 2015 managed only 21 mpg city and 28 mpg highway in the EPA's tests, disappointing for such a light car powered by a naturally aspirated 2.0-liter engine. The new car tests much better: 27/34 with a manual transmission and 27/36 with an automatic. The MINI Cooper S Roadster was about equally efficient when equipped with a manual transmission (26/35), a little short with an automatic (25/34). The new MINI Convertible, if it shares the Hardtop's EPA ratings, won't be as efficient with a manual transmission (23/33) but will be as competitive as its predecessor with an automatic (26/33). The Scion FR-S barely out-economizes the old Miata with a manual (22/30) but is just a couple mpg short of the new one with an automatic (25/34). Premium fuel is recommended in all of these cars. The new Miata can use regular unleaded at the cost of some responsiveness. In my real-world driving of the new Miata with an automatic transmission the trip computer reported a suburban average around 30 mpg. On a 60-mph highway the average can reach 40, about 4 mpg better than a Scion FR-S and 5 mpg better than a MINI JCW Clubman, both tested with manual transmissions. Drive at 75 mph with the top down, though, and the reported average will fall to 34 mpg. The largest fuel economy advantage over the Scion FR-S appeared when both were flogged along Ohio's Route 26. The Scion's fuel economy dipped into the high teens, but the Mazda's only into the mid-20s. The most likely reason: the torquier, far less peaky Mazda engine doesn't have to be revved nearly as high to reach its sweet spot. The JCW Clubman, its turbo reducing the need for fuel-guzzling runs to the red line, fell between the two with a "spirited driving" average around 20 mpg. Overall, with the redesign the Miata's fuel economy has gone from worst to first. see full Mazda MX-5 Miata review
Mazda MX-5 Miata Real Gas Mileage: Cons
YearComment
The first four "why nots" shouldn't have come as a surprise to anyone. This one might. I didn't ding the MX-5 Miata's engine for its power output, but I am going to ding it for its fuel input. While EPA ratings of 21 mpg city and 28 mpg are hardly abysmal, the FR-S does better (22/30) and a 315-horsepower Porsche Boxster S does about as well (20/28). With one of Mazda's new SKYACTIV engines, the Miata would go much farther on a gallon of gas. (The 2,900-pound Mazda3 is rated 27/39.) But this engine won't happen until the Miata is again redesigned. see full Mazda MX-5 Miata review
