Purchased Oct '06, mileage calculated after each fillup, 3146 miles and counting. Driving is typically 5.6 miles to work and back with occassional trips outside of that range. Some weeks are nothing but that commute, other weeks include 50 mile highway runs to remote jobsites. '07 Yaris Hatchback Automatic 25.71 24.69 28.52 28.47 28.96 28.55 26.52 27.11 29.17 28.19 27.68 29.91 Total average is 27.79mpg. This includes stop and go traffic on my short commute to work, long hauls, etc. Doesn't fluctuate much at all. I start and stop at an easy pace but do have to drive above the speed limit to keep from getting anihillated on the interstate and turnpike. Located in Palm Beach County, Florida. Our only hills are the highway bridges.  I run with air when it's hot. In our brief brush with weather that is not quite hot as summer (I hesitate to call it winter) I would drive with my windows down when in regular traffic but would put them up and use vent when at highway speeds. Never saw any of that reflected in the fuel use. I took it in to the dealer to see if there was anything wrong with the car and they said no, ran it through the computer diagnostics and everything. I kept getting mixed message on whether modern engines still need a break-in time, whether fuel economy improves in time, how long it takes for the onboard computers to learn your driving style and adapt to it, etc. The dealer told me the computer takes about 5000 miles to learn you. I asked him what happens when the battery is disconnected. He said there's a 20 minute capacitor in there and if a new battery isn't hooked up by then the computer resets. WTF? My bloody cell phone can store my info in non-volatile RAM when I swap batteries pretty as you please. Now what is this overdrive everyone keeps talking about? There's no "sport/economy" button on the automatic column like I had on my previous '91 Honda Accord. The shifter does have that left/right rocking motion it can do but I could never find anything in the manual to explain what that was for.

Replying to: jollyreaper (Feb 28, 2007 8:54 am) Well, perhaps by the time you reach your destination the car is barely warmed up. Also, some places have the 10% ethanol in effect. Overdrive is 4th gear (someone correct me if I'm wrong). Yes, One drop-click below Neutral is what you should be driving on. If you push it to the left, you are limited to 3 gears, which will have drastic effects on your mileage, especially during those 50 mile highway runs.

Replying to: fastrunner (Nov 07, 2006 3:10 am) I'm a big coaster too, with my Honda Fit. I shoot for half miles, though usually do only 0.1 or 0.2 (it adds up). In hilly terrain you can coast a lot more, of course. As an alternative to suddenly adding gas if someone comes up behind you, you can gently give it a bit more gas at the beginning in order to maintain polite speeds for the coast. I don't feel bad creeping to a stop light, but it's rude to go too slow if someone needs to get into the turn lane ahead or the light is green. To push things further, you can also sometimes use engine braking (which uses no fuel) in situations where you need to decelerate, rather than coasting (which uses a small amount of fuel to maintain idle). Not sure if I'm right about that last one, though, just what it seems to me.

Replying to: jollyreaper (Feb 28, 2007 11:31 am) Could I have been causing damage driving in third gear like this?" See pages 125-127 of your manual. It is explained there and will answer your question. Don't feel too bad; I did the same thing. But, fortunately it was with the Scion loaner we were provided before our Yaris arrived. My wife was the one who brought it to my attention when she noticed me leaving the shifter in 3rd gear. Although I initially protested she said, "I read it in the manual." Upon actually looking at the labeling of the shifter and "thinking" I had to agree with her.  What are ya gonna do? It isn't a design or documentation deficiency. It's "us." If you're used to driving a car with an "in-line" shifter pattern it's an easy mistake to make. Maybe they could improve the manual with some bold, colored text to draw this to the readers attention, but a lot of people would probably still overlook it. Who reads the manuals anyway? |

Replying to: nippononly (Dec 01, 2006 6:23 pm) Do you really need to rev-match on contemporary cars like the Yaris? (Is this what they used to call "double clutching"?) I thought automobile manual transmissions ensured the gears were always in synch before meshing, in comparison to, say, my vespa scooter which would grind if you don't match the rpm's.

Replying to: jkandell (Mar 02, 2007 9:23 am) And no, that's not double-clutching.

Replying to: jkandell (Mar 02, 2007 8:45 am) Any time your engine is running, it is using gas. It can't run without it. So coasting in gear (with a manual) using the engine to brake uses roughly the same amount of fuel as just allowing it to idle. But engine braking will increase the life of your brake pads and helps the piston rings seat as well.
