Fuel Economy - Page 79 - Toyota Yaris Forums

swng · 07-31-2007, 05:29 PM

Here is an article which I think is basically about fuel economy. IMO, it is not talking about new discoveries in this field. Yet it is comprehensive enough for day to day F.E. conscious driving purposes. One of the good things about it is it does give an estimate of how much fuel in terms of percentage a certain measure can help save: http://en.autos.sympatico.msn.ca/gui...mentid=4907539
Enjoy!

I can't see the car doing better after it breaks in, but if it does this FE could get amazing!

Wow that's really good. Congratulations.

4.9 liter??.. this car should be between 5.5-6.9 l/100km how did you achieve that??

Your location shows "Toronto", so in order to get that kind of FE on the 401, either your commute is at 2am or you weigh less than 10lbs

or both

The 401 is one of the most conjested highways in North America with average speeds during rush hour of >40km/hr. I can't believe that any driver of average weight can achieve 4.9L/100Km driving the 401 during the day

My Yaris is automatic, I commute from Markham to Toronto daily (40Km), my tires are at 42psi, I'm slower than 75% of cars, accelerate slowly from stops, I coast down hills whenever I can (my faves are leslie southbound and bayview south @ pottery rd), limit my use of ac, there is no extra weight in the car, coast to all red lights and stops, I only take one short 10Km trip each week to grocery shop, I don't idle, I don't warm up the engine in the morning, etc.

YET my best FE ever was 5.9 (575km on 34L). Your 707Km on 34L is 23% better than that. Either I'm missing some voodoo driving secret or, with all due respect, you're not telling us all the facts.

My best tank is also 4.9, to and from the Sea-to-Sky Highway with two passengers, speeds ranging from 30 to 80 km/h, lots of crawling up slopes and riding down the other side with DFCO.

Now I'm consistently 5.2 in all city traffic.

my mileage dropped off considerably for the past two winters, in fact i might actually get 10 mpg less in the winter than i do in the summer.

but the disclaimer is that most of my driving is short city trips, so in the winter the engine never has much of a chance to warm up.
but i have also noticed poorer mpg on the highway as well in the winter.

Cars tend to run on less fuel in warmer weather. Even with my old cars, I have differences in the winter.

i knew landscape's got something to do with ur 4.9l/100...

roxy84 · 08-02-2007, 06:29 PM

talk about consistency. my last four tanks on the yaris:

431.8 mi/10.17 gal=42.4 mpg
424.9 mi/10.016 gal=42.42 mpg
427.3 mi/10.041 gal=42.55 mpg
422.8 mi/9.88 gal=42.79 mpg

im all for consistency, but this is just getting boring.

this with a work commute of 70% hwy/30% city. some of my driving i would categorize as neither city or hwy, but rather "suburban"(.5miles-2 miles between lights, 40-50 mph). if one is good at anticipating lights and adjusting accordingly to avoid too much stopping and starting, "suburban" driving done properly may result in mileage equal to that of some highway runs.

Canuck · 08-02-2007, 11:08 PM

And when one is stuck in traffic, 'hyghway' driving is worse than city. Hate the 401!

First fill up yesterday. 7.78L/100km. Not bad considering that I'm still breaking her in, I spend way too much time idling on the 401, and my 19 year old drove it some :)

marcus · 08-03-2007, 10:54 AM

i know a lot of people here believed in DFCO..if you ask me it sounds made up.....downshifting raises revs vs neutral half the rev..and i dont know how the car will still be running if the fuel was cut off...just my thought of it..

im assuming the "scangauge" can confirm this..anybody???

Because the wheels are turning the engine instead of the other way around.

aca72 · 08-03-2007, 01:15 PM

My first fill up on my Yaris S M/T:

33.49 MPG: racked 332.9 Miles and filled 9.940 Gallons

Driven mostly on rush hour highway traffic and city streets. It's still in its break in period so I know the mileage will improve later on.

Bredayaris · 08-04-2007, 08:49 AM

Last time i drove a trip for 150 km, my diesel Yaris used 5L/100km, that is 47 mpg (US). My average on the highway was 80.8 mph.

Now sometimes i'm going faster on the highway and have a lot of citytrips, on the highway i sometimes drive 93 mph and now it uses 41.67 mpg (US).

I always use my airco.

joe keeney · 08-04-2007, 09:20 AM

Over 2000 miles changed oil at 1400 gtx getting 40.2 mpg thats running the air. Also its automatic. nocity driving...

woof · 08-04-2007, 01:47 PM

I can't believe some of these mpg figures here.

My LB has 16K miles on it and I got 39 mpg on a short trip ONCE but usually get 34 to 36 in and around town which includes 50% at 60 to 70 mph. I am not a hot rod guy and alternate between "driving by the handbook" to punching it to merge on the highway.

I tell most people who ask that I get 35 mpg regularly with my 5-speed.

Bredayaris · 08-04-2007, 04:27 PM

I do get those mpg easily but i have to say that i have a diesel engine in my Yaris.

34 to 36 is about what i get driving around town, i think this is in line with the epa estimates.
