real world smart car mileage
04-04-2015, 12:21 PM #2
Thanks for sharing what your scanguage provided. I am very curious. 1) with the temp being 42 degrees, you would not have run your AC. I live in FL and run my nearly always. 2) How do you drive? Your consistant driving habbits, are they "like you stole it" IE drive it hard or do you baby the car during acceleration. 3) Do you auto shift or paddle shift? 4) Do you regularly practice any types of hyper milage actions such as putting the car in neutral and coasting often.
IF so, please explain. I've only had 50+mpg one time with my smart and would love to see it more often. Thanks.

i do get better gas mileage at 60F, it takes longer to reach operating temp, the smart uses more fuel when below 190F. i use moderate acceleration, although i did do the "drove it like you stole it" a week ago going home from work at midnight when i came along some kid with a loud pontiac who was gunning it at the lights.
i try to keep the fuel rate during accelleration under 1.3 GPH, i had great traffic during that trip, i could have gone at any speed i wanted 95% of the time, i kept it at 55-60mph. i have a pure, so no paddles, kept it in "auto". no coasting, there are few times when coasting is beneficial in a smart, the smart will idle at about 0.20 GPH while coasting, when you lift the throttle in gear it drops to 0.00GPH and your mpg goes to 9999MPG (the computer cuts off all fuel to the engine and it's running on NOTHING)
i installed the SG2 in november, so i have yet to use it with the AC on, last year i rarely used my AC, only before job interviews. the SG2 can notice when your headlights are on or the blower is on, fuel consumption goes up 0.01-0.03GPH at idle, i am curious what happens when it's running the AC compressor as to driving with the driver's window down with it off.
one of the biggest factors in normal driving is anticipating traffic/lights ahead, not racing to red lights. i filled up yesterday on the way to work and so far i'm getting 48.5mpg for my commuting, it's going to be cold the next few days here, last night was 38F. if you're on flat land, babying it will get you better mpg's. i could see brief spurts of accelleration could equal the slower accelleration if you can ride along for a few miles before stopping again. there are times when i'll put it in manual and force a higher gear than D would pick, it likes to downshift in D sometimes and that will drop your mileage 20-30% over being in a higher gear at lower rpms. that's where the SG2 comes in handy, also monitoring your throttle while driving. i got a 10% increase just by installing the SG2, you become more aware of what you and your car is doing, how it reacts in different conditions.
p.s. i was contacted by the firm that trains smart "brand specialists" about this video, using it to "sell" the smart. this overcomes the EPA ratings with "real world" data. most cars will get a few percent below EPA ratings, i'm getting 20-30% higher than EPA in my daily driving. so the specialists will be armed with real world data in the showrooms.

Great video i just ordered my scan gauge. Will you tell me what type of mount you have it on and where you got the mount, thanks david

I drive my Smart back and forth to work on a daily R/T of 52 miles. I try and maintain a steady pace but 55-65 is normal on the highway. When I take the back roads I maintain 50-55 mph. My average mpg is 44. I do not use the paddles but let the Smart shift itself. Maintaining the tire pressure will help ensure good mileage.
There are some out there that get even better than me. I leave in Virginia Beach and the area is flat, no hills.

in "spud gunning", when i used hair spray for fuel, it fouled the combustion chamber quickly, going to "static guard" and pure propane, it burned clean and left no residue. now i have upgraded the ignition from a piezo electric BBQ ignitor to a 150,000V stun gun, nothing could foul that!

i just made another powerball/beer run, it was 70F outside, 37 miles there 51.6 mpg, coming back 61.6 mpg, trip totals, 56.6 MPG average, 42MPH average, 74 miles, 1.7 hours total time. not too shabby!!!

I just got my 2009 Smart and have yet to see high mpg. I have only 1,500 miles on it so far and was wondering if you got your high mpg right off the bat or did the engine need to break in a bit before you started seeing the higher mpg?
So far my average mpg has been the EPA's rating (36-41mpg).
05-01-2015, 12:22 PM #10
my first tank was 37mpg, the mileage goes up as the engine is broken in. i got 53mpgs on a highway trip at about 2500 miles. last week i made a 40 mile trip with an average speed of 42mph which yielded 61.6mpgs. i now have 10,600 miles on my smart and just had my second oil change at 10,300 miles.
i recommend the SG2, it will help you with gear selection in certain driving conditions. a "forced" gear change can get you an extra 30% increase in economy.

Cool, I will look forward to better mileage, I now have 2000 miles on my smart after several highway trips. Unfortunately here in Florida it is hot and I have to run the A/C or drive with the windows down and even then ya sweat and lose aerodynamics. I definitely will have to invest in a scan gauge but that will be next month as I just dropped my extra cash into a cruise control which I will be installing next week.
Long trips suck with no cruise control lol. In the mornings on my commute to work I do not run the A/C so maybe after I get a scan gauge I can see if I am getting good mileage then. So far I have only been able to do the fill up and divide miles by gallons put in. Not the most accurate way to measure mileage.
Thanks for the insight!

it depends on how i feel, the smart seems to run the same on 87 octane as it does on 93 octane. i usually run on sam's club gas, only buy other gas when out of state. i'm tempted to run shell with nitrogen in it. unless you are "hot-rodding" the smart, i think putting in high octane fuel is a waste. in my daily commutes, i never see 3000 RPMs, on occasional sprints, i'll run it up to 5,500RPMs, maybe running higher octane would be noticed then.

I was looking into buying a scangauge, but did some looking into the need and expense.I will not try to justify or put down the Scangauge, but the fact that it relies on the calibration by the car owner and uses data from the cars computer makes me wonder how to justify the expense. On smartcarofamerica web site folks have gone on and on about calibration or lack of fine tunability of the gauge. The data from the car can't be all that accurate either, hello, this is a mass produced inexpensive vehicle. Consistant for sure, but accurate?
The old method of using a vacuum gauge to give feedback to the driver relative to engine load is really all you need. That, accurate fill-ups and a calculator is the only way to get TRUE MPG. So don't show me a gauge on the dash and claim it is accurate. They are all relative. Our gadget oriented society gets carried away. Even the computer in the Prius I own disagrees with calculated MPG. As far as the scangauge's other functions, do I really care at highway speed? A USB to OBDII interface, software and a laptop will really let you analyze things. If I don't do that I still got the extra cash for MORE lotto tickets...LOL

it's accurate to 1/10 of a gallon on 7 gallon fill-ups. my trip to wisconsin for the smart rally was spot on, i topped off on each "arrival", the only variable was the pump in wisconsin. don't knock the lottery, 3 years ago i was one number off of $135,000,000 and 3 months ago one number off $250,000.
if your foolish enough to pop for $10,000 for batteries in a prius, i'm a genius for popping down $160 for a SG2. it would take over a decade for the prius to pay for the price difference between the hybrid and a regular car, by that time you have to replace the batteries :-P
05-14-2015, 12:23 PM #16
I was not knocking the lottery, I have actually won a few bucks. I defy you to find ANY non-hybrid car that has comparable features to the Prius for 10k less. That would be 13k since we paid 23k for ours. We looked. In addition to my knowledge only a handful of all the Prius's ever built have had to replace the battery to date. There are all kinds of us geniuses out there I guess.

For comparison; a slightly more spirited drive... yesterday I did the Cairns to Townsville round trip.
Air con on all the way; return trip was at night with lights on; day trip was with headlights in daylight mode (extra tail lights come on). CD player on most of the way. Paddle shift... still not keen on Auto. Passed the 10,000 km travelled since new, during the trip.
Scangauge Trip reports:
76 kph average (includes city driving at each end; highway is 100 kph cruise; speedo indicates about 106kph when Scangauge indicates 100kph. GPS agrees with ScanGauge)
6365 rm max (it's a turbo and loves to spin.. happy doing 100kph in 3rd gear... and that DOES NOT significantly increase fuel consuption rate indicated on the ScanGauge. I needed to blow some deposits out of the exhaust.)
41.4 litres of fuel consumed
5.8 lhk (40.4 mpg average)
so... I sort of agree with the 41 mpg highway fuel consumption as being typically achievable and is the norm for my driving in Australia. Any driver should be able to better 40 mpg highway, so it's a fair sticker. Not many will better 50 mpg... I probably never will.

ian, the AC is a killer, for my commute, it knocks 10-15MPG off my mileage in stop and go driving. when it's 75F and above, i have the driver window 1/3-1/2 down and the fan on dash level on speed one, then i get 52-61MPG when ther air temp is 85-90F. i have a job interview next week, i'll drive there with the AC on, supposed to be mid 80'sF, even though i worked at the place last year for 10 months, i don't want to show up sweaty.
i wonder how much stuff you can get in a modern engine, with modern fuels and synth oil after about 6200 miles... i can see older cars with coil fired ignitions and older, non-detergent gas and regular oil getting a little crap in them after 20-30,000 miles. i'm tempted to try our shell gas, they are putting nitrogen in it... nitrogen in tires, nitrogen in gas...
i'd be interested in what you could get at 80-90kph on a flat road, 80-85F in 5th gear... without AC.

Foo... I really wish the US would allow one of the diesel engines in the cars offered by smartUSA. I have a turbocharged 800 cc diesel-powered 450 Cabrio that gets 65 MPG around town. sigh...
05-20-2015, 12:24 PM #20
i'd like a turbo diesel, especially a MB... frikkin seirra club and damned algore.... global warming is a farce!

One of the smallest cars in the world, the Smart Car is manufactured by Smart GmbH. This is a wholly owned subsidiary of Japanese major Mitsubishi Motors. Used Car Prices It was showcased at the Paris Motor Show in 1998. It is a 2 seater vehicle available in 3 different engine configurations. Two gasoline and one diesel. A recent addition is the all electric motor. The engine is rear mounted in all the 4 variants. A talking point amongst a Smart car is the Smart Car MPG. It is one of the best in the world.
