Post Your Best Mpg!
 
OK all,

This is a post to find the maxed out limit of mpg for the iA. I believe I have reached my maximum within a few tenths or so. I believe some based on their driving habits and conditions may have reached beyond what I have. Please be known that I have intentionally tried my best to reach the best I could do.

I ask that the folks that post to this thread be as honest as myself and that the numbers posted are hand calculated, NOT From what the computer indicated as it is, But manually calculated via the gallons on your receipt and the mileage on a Full Tank a gas ONLY!

Also, If I may ask out of curiosity, the Mileage on your vehicle at the time you obtained your best mpg.

>:) Mine is 46.61 mpg @ 2160 miles

This picture is my best trip.

My best tank is 50.33mpg hand calculated - computer read 50.8mpg. 488 miles, trying to hit 500 this tank.
This was my latest fill up: the warm weather helped.
Edit: Roughly 9100 miles.

Awesome! You could easily do 500 miles if your willing to test the 2 gal reserve;) Nice....

How do you guys hand calculate your mpg? I got my car a couple days ago and its reading 26.6 mpg on the dashboard info screen. Am I reading this right? How come it doesn't change when I drive around, its just fixed at 26.6.

Use the infotainment menu. Each time you take a trip, it will indicate the average trip mpg you are attaining(In Red) it will reset with each trip you take. The Current (In Blue) averages all the trips you have taken into account. You can set your trip meter in the settings to Clear the Current Values each time you push the reset button on the dash.

So based on this picture attached, if I was at the gas station to fill. I would look at the trip A meter for the miles traveled and write it down. Then divide it by the gallons you put in the car for the hand calculation. Then I would push the physical trip A clear button on the dash. This will then clear the "Current value" and start a new running average. At the same time it will move the Bar to the left as a reference to you new average. Hope this helps

The 26.6 mpg you are reading on your dash is probally the setting you have currently selected by default. If you push the "Info" button on the steering wheel the same area on the dash can do multiple functions, real time mpg, range left in miles to travel, average mpg, average speed and so on. Your mileage will increase as the car is breaking in. But the infotainment graphic seems to be the best for monitoring you fuel economy.

This helps clear many questions I had. Thanks so much.

rwmorrey 05-23-2016 03:13 PM

There is no way you can't get better MPG than that. I also have a 2014 Mazda 2.0 that I got 55 mpg on hwy 5 two years ago. The info below is from fuelly. It has the date,miles tested,gallons,and price per gallon.

6/13/14 172.30 3.113 3.990

This is another example of what I'm talking about.

wtf how you getting 55 mph on a Mazda 3

rwmorrey 05-23-2016 04:16 PM

That was in cruise control over almost 200 miles of driving. Normal highway mpg won't get that much, but the link below my original post shows someone that is getting around 50 mpg on the highway. I want to do the same test with my 2016 Mazda 2(Scion IA).

What is your average per Tank? I have seen up to 62mpg for short runs. But cannot get that kind of average with 445 miles on a tankful:)

Moe 05-24-2016 03:28 PM

That's amazing mileage which makes this a great commuter car, helps that its actually cool, unlike a Chevy Spark which while cheap... just doesn't check off all the boxes that the iA does, it gets even better when you look at the chance of buying one used, those that held out since launch can look into that now.

My guess is if you have a soft foot, you should be able to get 50 mpg or at least between 45~50 mpg on a Full tank average.

Got 507 miles this tank! Computer said 52.3mpg but it was closer to 51.7mpg (Didn't quite fill it, put $20 in)

rwmorrey 05-27-2016 03:40 PM

That is better than a Prius on the highway.

mhsmith57 05-27-2016 08:01 PM

3rd tank, driving 70+ mph, stop and go in the afternoon; 350.7 miles: 7.92 gallons to fill = 44.28 mpg. Can't complain for a combined mpg. Going on a 4 day road trip this weekend with lots of fwy driving, hoping to get into the high 40's. Enjoying the ride!

39.4 mpg, probably about 20-25 miles of moderate stop and go traffic (avg speed then was 21 mph) and then 210 miles on the interstate (80-95 mph, dash said avg speed was 87 mph from when I got on to when I got off the interstate). 6 speed manual, running premium gas (92 octane from wawa) hand calculated at 39.4, dash readout 37.6, fast acceleration (or at least as fast as the car allows lol) and A/C on full blast first half of the trip, half power the other half.

Lowest was hand calculated 31, dash readout 29.4, in heavy standstill traffic about 12 miles each way (an hour and a half each way, Clearwater beach), and moderate traffic for about 100 miles total. Total of 225.7 miles. Round trip average speed was 17 mph. A/C cranking the whole time, driving as fast as I could in the traffic.

41.9 mpg as of last tank! 130 miles, filled up when I left the house, set my cruise at 65 on a mostly flat rural highway from here to crystal river and back, only one stop round trip. Running mid grade gas (89 octane) because they were out of premium.

bobmrihpm 07-14-2016 04:38 AM

My last tank I received a calculated mpg of 48.1 back and fourth to work. Nearing 3500 miles the computer is now indicating 1/2 more mpg than the last tank. Their cannot be much more...

mikemc422 09-16-2016 09:23 PM

52.9 mpg! I stuck to the rural roads instead of highways with traffic for the last tank and got almost 53 mpg with the windows down staying around 50-55 mph most of the time accelerating slowly (shifting before 3k rpm the whole time). I have the 6 speed manual and am at like 9-10k maybe a little more maybe a little less and around 2.5 months with the car

oh what the ****... my third fill (850ish miles) and it's sitting at about 35mpg ... fuelly thinks it's gained 1mpg or so since my last fill lol.
Aircon is on 50% of the time...
Lots of shorter 3-5 mile hops (work is 4 miles away so.. barely warmed up by the time i get there) This accounts for about 30% of milage...
Few highway drives a week, about 15-20miles each way, when cruising, am usually around 75-80... when in traffic, more crawling... thankfully most of the highway times i'm on are in the 70+ speeds.
Is this sounding normal so far? (my mpg)
Thanks :)

btw... Jin, how to get fuelly as my sig?

Sounds normal, depends how you drive. I have a similar commute, just many more miles, and if I'm not driving for fuel economy I'll get 30-33 mpg. If I take a different route where I'm staying at 40-50 mph with very few stops and less hills, I can get upwards of 50 mpg on my dash for that trip without much effort. That's also with the a/c off, and the windows open. I've found that this car gets better gas mileage with the windows open than with the a/c on regardless of speed.

Sidey 09-19-2016 09:52 PM

yeah, getting the hang of what drive gives me best combo of efficiency and comfort...
when i do the commute down the highway, it's about 20 mile / 30 min drive ... and even with aircon on setting 1 or 2, it'll be over 40mpg.
my little hops tend to sit anywhere from 25-30mpg, usually with the aircon off.
i haven't tested this out, but does the higher the aircon setting, the less MPG?
thanks :)

Probably not, it didn't make a difference for me with anything else I owned (I tried a lot with my accord and civic) and if the a/c is on, the compressor is working just as hard with the a/c set at 2 as it is at 4, the only way I'd see a difference in gas mileage is having it on max a/c (regardless of blower speed) opposed to it being a notch or more from max a/c, I know that made a big difference with my F-150, but that also raised the idle speed, slowed down the truck, and made the blower work harder no matter what speed the blower was set as, whereas with this car it's a temperature setting with recirculating air on instead of outside air coming in, it doesn't seem to make more noise with the a/c set to max either.

54.2mpg coming home from work last night.

I drove 54mph for 16 miles of highway, I pissed off a lot of truck driver, but that is the absolute best commute mpg I've ever gotten.

Is that what the dash was saying though? Or was that hand calculated?

mikemc422 09-21-2016 12:09 AM

54.7 mpg, filled up at a half tank but I had the windows down, a/c off, and lots of dirt road traveling this tank (35-40 mph in 6th most of the time on the recently-leveled dirt roads, 20-30 on the others depending on how bad they were) and a long stretch of rural 'highway' with the cruise set at 40 mph in 6th (still 5 over... the speed limit sucks, it's 35 on a wide open straight road through the woods for 24 miles from the main highway to the house I went to, and a cop was riding my bumper on the way out to the main highway)... the highest speed I hit that tank was probably 55-60 on the main highway, but it wasn't long-lived because I wasn't on that road long.

Sidey 09-21-2016 10:12 PM

and i thought i did great this morning on a 40 mile round trip down the 91 ... no ac and moving mostly around 65-70 .. including about 5 miles of suburbia ... 48mpg.

remusrm 02-21-2017 11:23 AM

Averaging 35.6 mpg hand calculated with a/c blasting most of the time and 80% of driving in the city. Can't wait to see what I'm averaging after summer when I don't need the a/c. Best trip so far was mostly highway late at night so a/c was off and no traffic. I have about 2,000 miles on it so far

FritzR 08-02-2018 11:10 PM

51.67 for 434 miles at 21000 miles. Fuel economy monitor is about 1% too high. This was mostly back roads travel at 45 - 50 mph with the windows up a/c on. I'm keeping a log and am at 47.3 for the 25587 life of the car. It's a 2017 with an automatic. When cruzing slow it tends to run at 1000 - 1250 rpm.

At a steady speed on a flat with no wind cuise control on windows up with the fan on 1 a/c off it gets 44mpg @ 70 mph, 48 @ 65, 52 @ 60, 56 @ 55, 62 @ 50, 66 @ 45, 72 @ 40, 76 @ 35. That's all in 6th gear. Surprisingly linear

Hi all. I've been hypermiling since 2006 in a variety of cars - Honda Insight, Nissan Maxima, Honda Civic, and even my wife's Toyota Rav4... all of them with stick shifts ( including my Yaris )

What i've noticed over the years is that each vehicle likes certain things, and it's on you to figure it out and develop a special way of driving the car. Lemme tell you a bit about the other cars' designs and then i'll talk about the Yaris..

My '98 Nissan Maxima had a 3.0L motor. It was fairly aerodynamic, but the drivetrain drag was the biggest fuel suck. The strategy for optimal fuel economy was to stand on the throttle and then coast in neutral as much as possible. Engine braking was very helpful too, as the engine uses a significant amount of fuel while idling. My fuel economy record in that car was insanely impressive - i would regularly get 32-35 mpg highway doing 60 and conserving momentum as much as possible in the city. One day in perfect conditions, i got 40.5mpg over 6 miles! this is on a car rated for 27 highway!

The 2000 Civic EX seemed to be well optimized across the board and the best technique for driving it was just to go slow and be in the highest gear possible at all times. My record run was 47mpg. There is not a lot of room to exceed stock fuel economy..

The 2001 Insight had a dying hybrid battery and i regularly saw MPG in the 50's to 60's. Because of it's diminutive size, it LOVED being behind semi trucks. I could see 80mpg-90mpg for the sections when i was a car length behind a semi. Drivetrain loss with the 1.0L motor was ULTRA low, so there was rarely a reason to pop into neutral - also, you'd reduce battery charging, which you absolutely needed.

2001 Toyota RAV4 2.0L AWD was non-optimal in a lot of ways. AWD gives you increased drivetrain drag, so the Maxima trick needs to be applied. The car is also an aerodynamic house of horrors. One has to combine the trick of going slow and disengaging the drivetrain as much as possible to get a maximum of... drum roll... 35mpg.


Now, what about the Yaris? :)

I'd say that the Yaris is much like the Honda Insight, in that it is well optimized across the board. The engine is exceptionally efficient for it's size ( major hats off to Mazda ). The aerodynamic footprint of the car is similar to a Prius. Just the other day, i parked next to a Gen 2 Prius.. the Yaris is roughly the same height, but about a foot narrower! The front end of the Yaris is less aerodynamically ideal than the Prius, but overall i'd guess that the cars are close in terms of their CDA.

This car doesn't seem to mind whether you keep it in gear or not. It also likes being lugged around 1,200-1,500rpm. Once i hit 40mph, i'm in 6th gear whilst in the city. If i need to pass someone, i might just wait for a perfect opportunity rather than downshifting. Engine braking does not yield much improvement in the fuel economy versus idling your way to a stop light.

This car is extremely two sided. On the highway, you will see fuel economy numbers that rival modern hybrids if you simply drive at 60.. 65mph.. thanks to the car's excellent aerodynamics and drivetrain.
In the city, the curb weight of the car doles out cruel punishment. It is critical that you maintain momentum, as this car is just as heavy as other vehicles in it's class. That means anticipating stoplights and rolling to stops and gradient braking as much as possible. Without these driving tricks, it's easy to get 20-30mpg city.

I actually picked this car over a brand new Honda Insight when i compared the highway fuel economy numbers in real world driving. In my test loop, i handily beat the Insight by +10mpg. Recently, MPGOMatic hypermiled a new Insight and only achieved 68mpg at an average speed of 40-50mph. My record at a steady 60mph is 69.5. I believe that this car could exceed 80mpg in the right conditions.

Mazda, err, Toyota left a few optimizations on the table when they designed this car that could be used to increase the fuel economy:

1) The car has a very large oil volume relative to the size of the engine ( hence the ~7500 mile oil change interval ). Unfortunately, this leads to longer warmup times and poor fuel economy in short winter trips. A variable grill flap could have been installed to counteract this and would shorten warmup time significantly. Luckily, this is fixable with seasonal application of duct tape, or preferably a foam insert.

2) The underbody wasn't given much attention as the Mazda 3 or other larger cars. There is a lot of room to improve here.

3) Weight reduction would be extremely helpful. I have not analyzed this yet because of worries of getting caught in a warranty trap with Toyota.

4) The rev hang programmed into the car is horrific and possibly a culprit in the substandard city fuel economy. This car wastes quite a bit of gas going nowhere in neutral while shifting.

So yeah. I believe that this is a fantastic hypermiling machine with a few flaws. An 'eco' version of this car would butt heads with hybrids.
