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]

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.

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 :)

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.

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.

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]

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

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]

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.

Bredayaris, I was just ranting in a thread I started elsewhere about the USA not getting the "good stuff". I would kill (well, maybe throw a fit) to get a small diesel here. But, Big Oil and Big Pig Iron are joined at the board room to make sure we always have a big demand for petrol.




I'd dump my LB in a second for one of these....but, we will never see an Aygo here. Sigh.

Between 4,000 to the current 13,000+ I have only had 3 tanks below 40 mpg...1 was on a trip at 70 to 80 mph (36 mpg), 1 with air on (38 mpg), and 1 must of stepped on it too much (39 mpg). Most of my driving is 55-60 mph and usually 20 miles long (automatic), lowering springs, and 40 psi in tires.

my first tank with my new yaris liftback auto trans and i got 38.45 mpg with my normal everyday suburban driving with the a/c on.

I broke the 45 mpg barrier

I did it twice this past week. Once going across Canada-- cruise set at 62 mph and then in the mountains of New York. What amazes me is that it was in the mountains of New York that got the best mileage. I would have thought that running across the flat Canadian turf with cruise would have given me the best results. But in was the 'engine-braking' down the mountains that gave me the best yeild. Don't understand it, but I'll take it.

Look out 46 mpg!!

I've noticed this hill/mountain thing also! Theoretically going up an incline conservatively you could get 25-30 mpg....going down is free...so you could get 50-60 mpg (maybe theory isn't real life,but.....), while driving 62 on the flat may only get you 45-50 mpg!?!? The little stops and goes are what drop you down. Wish automatics had DFCO in drive.....3rd is usable only on very steep downhills at 50 or below or for stopping.

It gets even better as it breaks in!
