mine has 7700km on it, so it isn't too new

foober · 06-15-2006, 11:16 AM

Thanks stuffy for doing that experiment. I would think that fast starts and running the engine hard would eat up more gas. My little lift back yaris has so much pep to it I'm having a hard time not going faster than any other car on the road. I'm really amazed how much zip my yaris has. It loves to cruise at 80 miles an hour on the highway. And i'm always having to try and slow down. The liftback just wants to go fast. And I'm still getting 38+ miles to the gallon. I really want to trade my toyota tacoma truck in and get another yaris but I really need a truck.

yeah, i had beenconsciously taking it easy up to this point because i wanted to see how good the fuel economy could be, but i also wanted to see what happens to the fuel economy when you push it a bit.
i'm sure evereyone here has different driving styles, and with such wildly different fuel economy reports, i wanted to see for myself.

I have a question regarding a/c, yes I know it eats at your gas milage especially if your going up hill on a hot day, but I usually don't use my a/c, only if really needed then I turn it off, anyway since I don't use it, I usually just turn the dial to cold and have the air flow come from the out side, like the vent symbol and the symbol for when the air comes from beneth the dash? Know what I talking about? Its the setting where air comes out of the vents on either side of the cabin but not the middle ones (at least not as strong-hope that made sense) Even if the day is "warm" at least not above 80, it gets fairly cold or at least keeps me cool but I didn't push in my a/c button, I'm I still eating away at gas but not as much if I had my a/c button on? I assume obviously the condenser or whatever is still working just not extra hard cause the a/c is not on, but I don't know the technicalities of it, any help or anwser would be appreciated.

Update:

608km on 36.5L. All city driving.

6.0L/100km

swng · 06-15-2006, 08:01 PM

Here is my update:

628 km for 42.929 liters. That is 14.63 km per liter, or
41.348 mpg Imperial, or
34.45 mpg US, or
6.835 liters per 100/km.

The A/C was on many times and the time ratio between city and highway driving has been about 35/65%.
Warm weather helps.

Ryu · 06-16-2006, 03:29 AM

Swng, the fuel capacity for the yaris is 42Litres, isn't it?

Well actually, I think that's the only way to get a/c without push the a/c button. Its to turn the nob pointing to 'air out to dash'. I am sure that is using a/c because its a heck lot cooler. so instead, might as well use the a/c so it points directly to ya. ha ha.

Yes, officially it is 42 litres. However, if you fill up your tank until it almost spills, you will be able to squeeze in more than that amount, presuming that you start with an almost empty tank. Frankly, I do not recommend that you do so. I do that just to improve the accuracy of my mpg calculations.
Some previous pages of this thread contain more discussions on this subject.
Thanks for your interest Ryu!

Ryu · 06-16-2006, 09:11 PM

Thanks for your explanation Swng, then that make sense.

However, I go fill up after 1 bar is gone cuz of the cheaper gas price,
and it turns out 9.621L for 143.2km, which is 6.718L/100km.
I thought the car will stay around 7.3L/100km forever cuz of about 10 fill up after I got the car. I just got 6.92L/100km last fill, it seems getting better and better now.

This car is full of surprise

Thanks for your anwser...but you are right about staying cool without pushing the button, if I flip the lever so the air circulates within the cabin it starts to get warm but when I flip it to circulate air from the outside it cools down. Thanks again.

415 clicks / 33 Litre

Number one, it was all cities. Two, I blasted my a/c like there is no tomorrow lately, it's been 33+ as of late. Even during the night is pretty hot.

fearturtle44 · 06-19-2006, 02:08 PM

Selecting the fresh air setting only brings in the outside air. So if it is 95 degrees outside, then this setting will NOT do any good. Only the AC button will help. However, on those cool morning or cool evenings, the fresh air setting might be all that is needed.

swng · 06-19-2006, 06:10 PM

If you wish to rely solely or heavily on the "cool" air from outside, please consider buying a sun shade to prevent the sun from shining directly into your car while it is parked. Even the most expensive types should be quite affordable and they are effective. In the long run, because of the resultant reduction of the A/C's workload and hence improvement in fuel economy, the sun shade will pay for itself.

spacemanoeuvres · 06-19-2006, 07:15 PM

Just filled up for the first time on Saturday.

Liftback took 11.009 gallons with the odometer on 395.

That's approx 35.9 (US) miles per gallon...meh, not great

Driving was 65/35 highway/city and I had the AC running about 65-75% of the city miles.

The car seems to do much better with the AC off.

You are totally right on that...especially when its like 90 and above or even 80 but in my experience any day below 80 degrees, even with the fresh air setting, it gets pretty cool and I'm surprised as this is from the out side air as you were explaining so

Sure it may take a little longer to cool than a/c but overall it works, maybe most people won't be satisfied with it but I'm skinny and I'm pretty much a passive person generally speaking so I don't mind as long as I'm comfterable-each to his/her own. If I put on the circulation for internal only, and not coming from the outside it starts to get "warm" but if I switch it back it "cools" the cabin down, so I'm not complaining. Even summer evenings it cools down pretty nicely.

Couldn't agree more and I believe this is a cheap effective idea. Even if you have tinted your side windows, you could not tint your front dash windows, so a sun shade would be kick in nicely.

why? · 06-22-2006, 03:45 PM

Just filled up again. Went 447 miles and used 10.106 gallons of gas. That is 44.23 mpg US.

That is 5.32 liters/100 km.

Since I've had the car, I've driven 932 miles and used 21.64 gallons of gas. That is 43.07 mpg US and 5.46 liters/100 km.

I can tell my car is finally starting to loosen up a bit. I hope the increase in gas mileage continues.
