Toyota Yaris Real-World MPG

Comments

  • Purchased Oct '06, mileage calculated after each fillup, 3146 miles and counting. Driving is typically 5.6 miles to work and back with occassional trips outside of that range. Some weeks are nothing but that commute, other weeks include 50 mile highway runs to remote jobsites.

    Total average is 27.79mpg. This includes stop and go traffic on my short commute to work, long hauls, etc. Doesn't fluctuate much at all. I start and stop at an easy pace but do have to drive above the speed limit to keep from getting anihillated on the interstate and turnpike. Located in Palm Beach County, Florida. Our only hills are the highway bridges. :) I run with air when it's hot. In our brief brush with weather that is not quite hot as summer (I hesitate to call it winter) I would drive with my windows down when in regular traffic but would put them up and use vent when at highway speeds. Never saw any of that reflected in the fuel use.

    I took it in to the dealer to see if there was anything wrong with the car and they said no, ran it through the computer diagnostics and everything. I kept getting mixed message on whether modern engines still need a break-in time, whether fuel economy improves in time, how long it takes for the onboard computers to learn your driving style and adapt to it, etc. The dealer told me the computer takes about 5000 miles to learn you. I asked him what happens when the battery is disconnected. He said there's a 20 minute capacitor in there and if a new battery isn't hooked up by then the computer resets. WTF? My bloody cell phone can store my info in non-volatile RAM when I swap batteries pretty as you please.

    Now what is this overdrive everyone keeps talking about? There's no "sport/economy" button on the automatic column like I had on my previous '91 Honda Accord. The shifter does have that left/right rocking motion it can do but I could never find anything in the manual to explain what that was for.
  • What's this third gear thing everybody is talking about? How do you make sure you're not doing that? Every automatic I've ever driven, you put it in the D gear one click down from neutral, you know the automatic will select the right gear from all the options. Is this car different for some horrible and twisted reason?
  • lol When I was a kid I was all "rah-rah America first, buy American!" When I got my first car, it was a point of honor to get something American. Ford Tempo! And that's the LAST American car I'll ever drive. What a POS! I'm annoyed about my Yaris not getting quite the fuel economy I was expecting but in every other way it blows that Tempo out of the water, then puts the pieces back to together and refloats it so it can be blown out of the water again!

    I had a Honda Accord wagon as my second car. Damn good engineering but definately getting a bit old and long in the tooth by the time I traded out. I plan to own this Yaris until it falls apart, I hate car payments.
  • Driving is typically 5.6 miles to work and back...Some weeks are nothing but that commute,

    Well, perhaps by the time you reach your destination the car is barely warmed up. Also, some places have the 10% ethanol in effect. Overdrive is 4th gear (someone correct me if I'm wrong).

    Yes, One drop-click below Neutral is what you should be driving on. If you push it to the left, you are limited to 3 gears, which will have drastic effects on your mileage, especially during those 50 mile highway runs.
  • There is no emoticon for the look of blank....confusion. So I'm nerfing my car's performance with the left/right clicky thing? Why wasn't that in the manual? I read the whole transmission section to see if this had anything to do with anything and no mention of it was made! Ok, this is replacing "lack of cruise control" as worse feature about the car.

    Could I have been causing damage driving in third gear like this?

    "I do not slow down other drivers with my coasting. If someone is behind me, I use the gas to keep moving."

    I'm a big coaster too, with my Honda Fit. I shoot for half miles, though usually do only 0.1 or 0.2 (it adds up). In hilly terrain you can coast a lot more, of course. As an alternative to suddenly adding gas if someone comes up behind you, you can gently give it a bit more gas at the beginning in order to maintain polite speeds for the coast. I don't feel bad creeping to a stop light, but it's rude to go too slow if someone needs to get into the turn lane ahead or the light is green. To push things further, you can also sometimes use engine braking (which uses no fuel) in situations where you need to decelerate, rather than coasting (which uses a small amount of fuel to maintain idle). Not sure if I'm right about that last one, though, just what it seems to me.

    See pages 125-127 of your manual. It is explained there and will answer your question.

    Don't feel too bad; I did the same thing. But, fortunately it was with the Scion loaner we were provided before our Yaris arrived. My wife was the one who brought it to my attention when she noticed me leaving the shifter in 3rd gear. Although I initially protested she said, "I read it in the manual." Upon actually looking at the labeling of the shifter and "thinking" I had to agree with her. :blush: What are ya gonna do?

    It isn't a design or documentation deficiency. It's "us." If you're used to driving a car with an "in-line" shifter pattern it's an easy mistake to make. Maybe they could improve the manual with some bold, colored text to draw this to the readers attention, but a lot of people would probably still overlook it. Who reads the manuals anyway?

    "You don't "slam it" back into gear, you match the revs to the speed and slip it back into gear without a quiver."

    Do you really need to rev-match on contemporary cars like the Yaris? (Is this what they used to call "double clutching"?) I thought automobile manual transmissions ensured the gears were always in synch before meshing, in comparison to, say, my vespa scooter which would grind if you don't match the rpm's.

    Yes, all manual transmissions have synchros on every forward gear, but you can sure take it easier on your synchros if you do what I described. And certainly if the speed of the engine is very different from the speed of the gear you are trying to engage, you may get the occasional "crunch" if you don't rev-match, depending on how good your car's synchros are.

    And no, that's not double-clutching.

    Any time your engine is running, it is using gas. It can't run without it. So coasting in gear (with a manual) using the engine to brake uses roughly the same amount of fuel as just allowing it to idle. But engine braking will increase the life of your brake pads and helps the piston rings seat as well. :-)

    "Yes, all manual transmissions have synchros on every forward gear, but you can sure take it easier on your synchros if you do what I described."

    One way to match the revs from neutral to a gear is to blip the throttle a bit before shifting. I don't like that because it's wasted gas--which is what I'm in neutral trying to avoid. So what I've been doing most of the time is shifting into a slightly higher gear than is recommended in my manual. A higher gear means lower rpm, which results in a closer rev match to neutral; and since I'm already coasting I don't really need as much torque. Make sense?

    If you're idling the engine has to use fuel to keep things moving just enough. But if you're engine braking, doesn't the ecu on cars like the yaris shut off the fuel injectors? The moving pistons from momentum keeps it "running", no?
  • I read on & ON about this poor gas mileage and how it has GOT to be for a bunch of ridiculous reasons on "THIS" group. Yet every other REAL group of owners show a ton of us who just don't get good gas mileage!Seems to be tied to age AND driving expertize of the members of the "REAL" Yaris groups too.

    Comment : "" NEWS: Toyota recalls vehicles over faulty engine part

    TOKYO (AP) -- July 18, 2006 — Toyota said Tuesday it is recalling about 420,000 vehicles globally, including some Echo and Prius models sold in the USA, over a faulty engine part.
    The faulty part is the latest in a string of problems requiring recalls by Toyota, raising doubts over whether the automaker can maintain quality standards amid booming sales.

    The recall affects about 150,000 cars sold overseas, mainly in the United States and Canada, Toyota spokeswoman ...said. These autos were manufactured in 2001. ""

    Had you actually read the forum, you would've noticed it is talking about Echo and Prius models, manufactured in 2001. The Yaris is new for 2007, isn't it?


    There are so many more if anyone discovers GOOGLE......

    What do you consider "a LOT" ? 10, 15 people with mileage under 30 mpg ? considering the tens/hundreds of THOUSANDS of Yarii sold, in reality, your "LOT of folks" turns out to be a minor, and unfortunately unlucky, percentage.

    4 out of 24 vehicles from different states registered under 30 mpg. :sick:

    On the other side of the spectrum, 6 out of those same 24 cars registered 39+ mpg. O the injustice! :cry:

    Yes, that makes good sense, but you should be careful not to lug the engine, which can damage it and/or the transmission over time.

    And in the larger picture, you have to ask which will cost you more over time, the 0.05 ounce of gas that throttle blip costs you each time, or the extra bite out of your gear synchros each time you put it in gear.

    No, the throttle plate has an idle position that allows some air/fuel mixture to get through at all times - this is where it sits when you are engine braking. That air and fuel has to be burned or the engine would flood as you were driving along. Not to mention, you would have the most drastic engine braking ever! You would never need your brakes at all with that much engine braking. :-)

    Turning your ignition off while the car is running turns off the fuel injection system. Imagine doing that, and that is how much engine braking you would have if normal engine braking worked as you described. Of course, that would be super-jerky and inconvenient - in fact, that is why Toyota came up with HSD, to do exactly what you describe for real! In Toyota hybrids, the gas engine ignition and fuel injection shuts down as soon as you step off the gas and the engine itself quits - the electric motor steps in to make the transition smooth (eliminating the "super-jerkiness") and collect electricity from the car's momentum at the same time.

    Try simply reading the TRUTH at:

    http://www.fueleconomy.gov/feg/calculatorCompareSideBySide.jsp?column=1&id=22749- -


    ......... Yes, I have seen the new EPA MPG estimates. Did you read the fine print "Use the new EPA MPG estimates to compare to 2008 and later model year vehicles."

    This will be the new method of estimating mileage in future vehicles. The numbers they have posted for the Yaris are simple calcuted estimates for 2007 and older vehicles. Keep in mind the new system recalculates EVERY car's mileage, not solely the Yaris. Therefore, you will see a drop in Yaris mileage estimate, as well as any other cars, including your Hyundai. :)

    Furthermore, while this is an "estimate," no guessing/approximating speaks louder than the actual numbers posted by drivers themselves. AGain, look at the average : 34.5 based on 24 vehicles.

    Aren't you the OP that ran out of gas because you failed to notice your gas was blinking? ...seems to speak volumes about your attention to detail...

    What is the point of this link? Yes, this person is getting under 30 mpg. I guess the sky is falling and we need to recall the Yaris....what a horrible car. Can you believe someONE actually got less mpg than what is stated on the label ???!!!

    o for comparison...I'm getting 35 mpg in the city. Guess they need to recall this one too, huh? ...better start shopping for that Accent..
