What I'm trying to state is:
1. Both cars ('05 and '15) have a 11 gallon tank and a 2nz-fe - 1.3l engine. 2. I can drive 435.1km (270 mi) with my '05 and 253.9km (157.7mi) with my '15 yaris. 3. My dealer says it is normal since the engine is in a break-in period, but after that it should give me a better fuel consumption. That said, is this true?

That is a very dramatic difference if you look at the raw numbers.
About 127 miles for 11 gallons that is almost 11.4 miles per gallon. Doesn't sound correct to me but I'm no engineer. I would contact Toyota just to see what they say. |

they told me to keep tracking it until the 1000km checkup, and they said that the fuel consumption should improve, which doesn't make sense to me. I've searched the web regarding this and i've found sites that confirm that break-in engines tend to consume more fuel but there are also other sites from other countries were this model is sold and they also complain about the high FC, and their numbers are almost the same than mine. So I guess i'll wait to see what happens

I am. Mine is 90% city mileage, often stop and go, then stop, then 90 mph. A/C is on near enough year round. And I'm getting 35 mpg all day long. Manual five speed, 1.5 l, 106 hp.

You would have to be stuck in total gridlock for hours daily to get that low of MPG on a Yaris. |

Yup........I do 340 - 400 miles on 9.8 US gallons all the time. I average 75mph but I also go way over that speed on every that and red line it.

I've noticed most of you have 1.5l engines. Would that make any difference vs the 1.3?

It is true that a new engine will burn a LITTLE more fuel during break-in, but the mileage numbers and range that you are reporting are very, very low. In fact they are so low that I immediately question the accuracy of the data. I am not calling you a liar, I am simply saying that these numbers have not been placed in their proper context. A car that was showing those numbers would almost certainly be displaying other signs of trouble. Yet you say it is performing normally in all other aspects, no check engine light, no rough running, etc. Correct? The only other thing I can think of that would result in the numbers you are showing without any other performance issues would be if someone was siphoning gas out of your tank. Do like Toyota suggested, track it over a few months and see. Make sure to use the exact amount of fuel added at the pump in your calculations. Don't guesstimate. P.S. If anything I would expect the 1.3 engine to be more fuel efficient than the 1.5 |

I think in the IQ the aerodynamics also come into play. Anyway I have no hard data on FE vis-à-vis 1.5 vs. 1.3, was just my gut feeling. I would think that in the same car the 1.3 would be slightly more efficient than the 1.5, all other things being equal.

Kitt, a quick question...Is there any way to toggle between kilometers and miles on your odometer display? Is there any chance that your odometer is actually displaying MILES?
Looking at the range numbers you quoted 253 is not that far off from 270 IF the 253 number you see displayed is actually miles that you are mistaking for kilometers. Just a thought. |

Most people just reset trip 1 in the odometer when they fill up, and take note of that number every time they visit the gas station. Drive drive drive, fuel gauge starts to blink, fill up with roughly ten gallons. Divide number of miles in trip 1 display by number of gallons (usually around ten in my case), get mpg.

and that is exactly what I've been doing, and I am surprised that also the FP on my old Yaris are low but it has always been like this. The only times I get it to show a higher performance is when I drive long distances
