Didier, I am sorry to say that, but are you sure your calculations are OK? According to Toyota, the best economy you can get is 4.3L/100KM or 65.7 MPG. And, as...
Sorry, but there is no rock-bottom, hard, never-to-be-breached, ultimate best economy... The values claimed by toyota in europe are purely fictional anyway -...
Hello all, Thanks to Richard to support my best trip fuel consumption figure. To TheRookie I can only say that I was myself surprised to reach so good results...
Hello friends ... Indeed. My best trip was 71.3 mpg over 25 miles on my way to work one day a few months back right after filling up (and when I was another...
Yes, I know that it is possible to apply some sorts of fuel-saving techniques, like driving slowly, no overtaking, remove antenna, fold mirrors, overpressured...
Hello Didier and all, I'm still not a Prius owner, but hopefully will be in the future :) Just out of curiosity: what gasoline did you use (brand/octane)? In...
Didier, I in no way wanted to offend you :) All I wanted to say is that there COULD be something strange in it (car doesn't calculate it right, for example). ...
Hi to all board members, Could you give me some indication regarding delivery times in Europe? Especially in Belgium, if there are any Belgian members who ...
The easiest way to beat your mpg figure is to drive slower. I don't know how fast Didier drives, but the maximum mpg for the Prius on a flat road is likely to...
With due respect to everyone - Does the Prius turn its owners into sad penncy watching people? cmon guys, its just as important to get there on time and be...
Joao I assume you are aware that the higher the octane rating, the less efficient the gasoline is? In other words the best fuel for your car is the *lowest* ...
Arnaud For Belgium I have no idea (Patrick, have you any information?) but in the UK 3-4 months seems to be about the average. If you are keen to get a Prius,...
Jerry, Are you absolutely sure that higher octane numbers = lower efficiency? How does that explain better fuel economy from higher octane (in cars designed...
Jerry,
Didier stated that the max speed was 100 Km/h, however he didn't
mentioned about what the average speed was.
I agree that the 35 Mph (60 Km/h) should...
Hi Arnaud, Back in May I was quoted circa 10 months for a "Jade Green" executive version with Navi. I am located in Germany. However, back in Mid July, I ...
Jerry, Sorry to disagree, but from my self experience (like I said in the last email) it's the other way around. For a start, higher octane is more expensive...
No, he's wrong. Here's the proof, taken from http://auto.howstuffworks.com/question90.htm BEGIN QUOTE The octane rating of gasoline tells you how much the fuel...
The delivery time in the Nederlands is 6 to 7 months, because of a great demand. Greetings, John Visbeen Prius website - http://home.hccnet.nl/jc.visbeen Prius...
Hey, I didn't say I drive like that. Some people however like to maximise fuel economy and I was trying to help. There is a very clear trade-off between speed...
Rookie I never said that 35mph was optimum, I only said it was economical. Driving at that speed is impractical for me much of the time and I wouldn't do it if...
Joao ... energy that fuel contains as you correctly say, octane rating is a measure of allowable compression which is quite different. Indeed engine knock is...
Jerry, The 35 MPh came from Didier's chart (from that 50 to 56 Km/h window) :)) Yes, 57.5 is great but the whole question is how to achieve 70+ MPG (if that is...
Jerry, What else can I say, it's so evidently clear to me, why don't you try it out yourself, that should convince you!? I promisse you, you will indeed take...
Rookie I hope you noticed that Didier went to the trouble of doing a UK version of the chart, and a US one as well. Click on the tabs at the bottom of the ...
I am not quite sure what trouble are you talking about. According to that chart, if someone drives 50-65 Kmh (31-40 Mph) and the temperature is 28 degrees...
Hi All, As a automotive engineer, I must agree with the statement of Jerry, that there is no direct relation between energy and octane number, but!!!, the...
