Fuel Efficiency and the Yaris

[Truwriter]

Lots of really technical talk about mpg here but I only know that I got on the interstate to visit son, traveled in Ohio (I77 to OH Turnpike and west) and had the cruise on almost the whole time (toll booths). When I arrived I gassed up and did my math and got well over 45 mpgs. I have a 4 door sedan, 2008, automatic and could not be more pleased. Vehicle is comfortable as well. The Yaris is fantastic.

Yes but at the expense of looking like a travelling juggler

What do you mean, exactly?

Just a passing troll. Don't feed him.

[jjonrofl]

To the people who get 40+mpg- do you do only highway driving? I do about 70% city / 30% highway and have only managed 33mpg... :(

Currently doing 47mpg, in my 1.0 3cylinder

What's the optimum speed for driving on say a flat road? Would it be 55 MPH? Less? If anyone has a scangauge, I would be interested in the numbers. I have a 6-7 mile section in my commute where the speed limit is 50 MPH but there are stop lights.

You're off to a great start, Rikster! You should be able to stomp on us folks in the U.S. that can only get the 1.5L.

Hi, KrazyDawg. Using the SGII many of us have verified that 35-45 MPH is the sweet spot for efficiency on relatively flat roads. The 10 MPH difference is a broad range that depends on many factors such as tire pressure, road quality, wind resistance, ambient temperature, etc., but the common sweet spot within that range seems to be between 37-39 MPH.

Thanks Bailout. There's been a few occasions where someone drives at 40 MPH on the 50 MPH strech and I usually go around because I thought the sweet spot was around 50-55.

Well it's not really fair, holland's landscape is all flat :D which come's in handy when it come's to fuel efficiency!

For most cars under steady state, level ground conditions, maximum mileage is found in the vicinity of 35 MPH.

And that's unfortunately where we waste most of our gas - every time we have to stop. Getting back up to speed is the killer.

I'd estimate that the Yaris achieves between 45-55 mpg if it is kept very steadily at 40 mph on a level road with no head wind.

Well I cant gripe! Just got my 2010 Yaris sedan last Saturday, filled up by the dealer, so not sure how well it was done. Anyways, I have a tendancy to "top it off" , but I filled it slowly and checked at the 1st click. 10.2 gallons,lol pretty low. 40.9 mpg for 418 miles .When topped off at 10.8 gallons its 38.7 mpg. Not bad for the first tank. That 418 miles is total on the car, so were a couple of thousand away from broke in. And to be honest, not being used to the car and not using the cruise much, I've found myself between 75 and 80mph at times. Anyways, lovin it so far!! I'm gonna bump the tire pressure a bit and see how I like it. I'm not gonna go the hyper miler route, but will adjust driving to a certain extent to help. I owned a 2001 Civic before this and routinely got 36-38 with it.

So far I'm very happy with my Yaris. Last week I drove 218 miles and put in 5.52 gallons of gas. Thats about 39.5 miles per gallon. In my opinion, thats really good.

About 80% of my driving is highway, the rest city. Awesome little car

You mean the real speed or the speed that speedometer shows. I just checked with navigation system that speedometer shows 4,4mph above real speed

I am using a ScanGauge II to help me get the most out of a gallon of gas. Since I got it, I have been monitoring the ScanGauge II and have been able to manage a new best of 47.5mpg. That was the fuel economy average for a ride home from work, a 34 mile drive. It is flat, speed limit if 50mph, and only a few stops... Ideal for generating great mileage numbers.

But 47.5mpg is in Prius and the econobox diesel range - AWESOME for a $15k car!!!

[BailOut]

^^ Well done!

[pawsplus]

Got 40 mpg on my second tank!! I drive mostly on state roads/back roads. Not too many stop signs but lots of hills and turns and slowing down and speeding up. Some in the city. Wasn't on the interstate at ALL during this tank!
