What Our Members Are Saying about the Real Gas Mileage of the Fiat 500

Fiat 500 Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
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

TrueDelta Reviews the Real Gas Mileage of the BMW X3

BMW X3 Real Gas Mileage: Pros
Year	Comment
2013	While the boosted four has a clear performance advantage, the swap was motivated primarily by the push for better fuel economy. EPA ratings are 21 mpg city, 28 highway, vs. the 2012 six's 19/25. An Audi Q5 comes close, 20/28, but with 211 horsepower isn't as strong. Despite weighing about 400 pounds less than the X3's 4,112, a Ford Escape with a similarly spec'd engine does no better. A Mercedes GLK350? 19/24. The Volvo is even worse. Compared to cars, the X3 doesn't fare as well. The roomier, nearly as heavy 528i rates 22/33. The crossover's larger frontal area and higher ground clearance take their toll as speed climbs. In our real-world sub-freezing suburban driving, the trip computer usually reported about 21 once the engine was warmed up, matching the EPA rating and quite good for a powerful, two-ton, all-wheel-drive vehicle. Engage an aggressive Eco Pro mode for a Prius-like throttle response and ultra-low rpm shifts, and mid-20s are easily achievable while high 20s are possible. I even observed 32 over one short trip where the lights were in my favor. But the cars behind you won't be happy. Conversely, enjoy the turbo at every opportunity and fuel economy will fall into the teens. A defeatable standard auto start/stop system operates a little more smoothly than in last year's 3-Series, but not as smoothly as it ought to. see full BMW X3 review

BMW X3 Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2009	4dr SUV 260-horsepower 3.0L I6 6-speed shiftable automatic AWD	Have noticed as low as 10 mpg in start and stop city driving. Average for daily driving is 14 mpg. It uses premium fuel so driving this car is already very expensive. see full BMW X3 review
2006	4dr SUV 225-horsepower 3.0L I6 5-speed shiftable automatic AWD	City driving fuel economy is not bad for an SUV. I average around 16MPG battling heavy traffic and my need for �enjoying using the accelerator�. Highway mileage is not so great. Cruising at 70-80MPH returns around 22MPG. see full BMW X3 review
