Fuel Economy

[BailOut]

marcus,

If you find a way that I can get a 1.3L (or, better yet, the 1.0L), here in the U.S. please tell me how. All we can buy here today, and what I have, is the 1.5L.

Well here's an interesting observation... I knew that air conditioning was quite a hog of engine power, and as a result, fuel, but it's a much bigger difference than I thought! Over here AC is more or less a necessity, but I've trying to do without it as much as possible, like int he evening, or on cool rainy days. Firstly you can feel a big difference in engine power especially at low revs, it feels a lot smoother, much harder to stall. And, so far, I have not yet finished this tank, but the meter's at the halfway mark since a few days, I have 270km on the tank, normally I only have about 200 at this point. So, it looks like I may finally get to 400km before refilling (normally I refill at about 330km, i.e. ~24MPG), which would mean close to 30MPG... Wait and see...

It is said here (please see link below), inter alia, that AC can increase fuel consumption by 20% or more in city driving. If you do not have time for the whole page, please go direct to the paragraphs captioned "Are you willing to pay a fuel penalty for all those extras?" and "Options for fuel efficiency":

BTW, after reading the whole page myself, I am quite happy that I have chosen a Yaris.

I will be very interested to see your report on the whole tank here eTiMago!

well the crappy thing is, now my fuel gauge has dropped two bars in one day, I just reached 300KM and 2 bars left. I know, it's somehow a feature of this fuel gauge that the secon half drops faster than the first, but this is ridiculous or maybe my messed up exhaust pipe had something to do with it, but I doubt that...

Sorry to learn about the sudden fuel gauge drop and the tail pipe issue. I have read your thread about the incident. All roads are hazardous!
Back to fuel economy, you are very right, the bars at the lower parts of the gauge do not last as long as the top one. My experience is that except in some extreme cases, each of those bars (except the last one about which I have no courage to find out more) gets about 50-65 kms in city driving and more in highway driving. As you and most users of this thread are aware, it depends on many factors. Long term averages are more reliable.
All the best and drive on for fuel economy!

Congratulations! Now you've made it!
Don't forget to share your experience from time to time.

The pipe is pretty small, and your dent didn't look good....I would say it sure isn't helping!!!!! Is the insurance going to cover?

heh...my wife and I are taking the Yaris to Key West...approximately 400 miles both ways two fill up when we go and when we leave are hoped...

Bon Voyage! Enjoy the good fuel economy of your Yaris and post your mpg here later!

[bigdoglover]

ok, here are the numbers from my next fillup-332.1 miles on 9.375 gallons of gas=35.424mpg. really drove conservatively-used the a/c very sparingly. this is suburban driving southside of chicago. typical lots of stop lights-a variety of speeds-no expressway driving. i can not see a way to ever get to 40mpg unless i throw out my rear seat-spare tire and lose my once in awhile passenger and lots of weight myself.

why would you get 1.3.. 1.5 is better...although 1.3 gives you slightly better mileage but slower though theyre like 86 hp... sorry we dont get 1.3 here in canada..? if i find something ill let you and everyone know aight!!..

[sherryberry]

Last fillup gave me about 35.4mpg... 319.6 at fillup and it was about 9.028 gal at fill up... this is all city driving.

We all have much more horsepower than we need. With the Yaris' weight we could easily get by on less than 33 peak hp.

You don't have to get there fast. You just have to get there.

Hence I would rather have the 1.0L than the 1.3 or 1.5. It would be even better if they offered a 1 cylinder at 300cc or so, especially if it were part of a hybrid drive train.

I generally get anywhere from 29-32mpg, 100% city driving. I'm taking the yaris for a 14 hour drive to north-east Quebec in the winter, I'm interested to see how many mpg I get. I'm really surprised how many mpg people are getting here. Also some good tips on saving gas, but 2000rpm while accelerating? I always tend to get real annoyed when someone in front of me takes a few minutes to get to the speed limit. I have the mentality that a car is meant to use gas and can't get around it, but I guess it's always fun to save at the pump too. When I used to own my 94 Probe GT I went through gas like crazy...had to be premium, too, or else the engine starts to bog down and eventually start to detonate. I think with my probe I averaged 14-18 mpg, that was for the 2.5L V6 with the 5speed. But then, I'd accelerate in first gear to 6-7000 rpm at most lights just because I could. 6000 would usually get to the speed limit, so thats usually where I stopped.

I agree , if they came, people would buy. When I had my Honda 600 coupe (600cc w/36 hp), I had all the power I needed.....75 mph if needed, with 35 year old technology. 1.0 liter would fit many peoples needs.

And 78 mpg isn't true also, ok behind a truck maybe with a little luck you get that mpg.

But in the other hand petrol in the States is getting more expensive i realize that but it is nothing if you compare it with Western Europe!

Petrol here costs 1,50€/ L,
that's 5,67 €/ Gallon,
that is 7,80 USD/ Gallon

I don't know what you guys pay for petrol but i think it's 2 times cheaper?!

As a matter of fact I once drove a VW Lupo as a company car when I was working in Germany. It was easily getting 75 MPG (3.2 Liter/100 km) Diesel without any tricks. I can't speak about the quality, but it seemed to be okay to me. They used titanium to lower the weight of the car. That's why the price was too high at about $23,000.

And then again the Lupo is completely overpowered with a top speed of 105 Miles. I wonder what the mileage would have be with a sensitive engine.
