i looked in to it
and here the base model is a few 1000 euros more then the prius
and is rated 5,26/100km

so when the poster in this topic tells me 3,5
CleanMPG reviews the 2007 Honda Civic 2.2L iCDTi Turbo Diesel. - CleanMPG Forums

i do not believe it

Well he drove 2840km with the car. So I would assume the collected data is true. But of course it is really impressive

Maybe after the shootout we'll see if it stays

I would definitely believe it. Wayne (xcel) is a serious hypermiler who gets insane mpg out of his vehicles. He was getting like 90 something with a manual Insight, high 40s with a regular Accord, and high 30s with a Ford Ranger. He was also one of hypermilers in the US Prius 100+ mpg 1000 mile tank back in 2006 (I think it was 2006).

If I recall correctly, he was able to get ~120 mpg with some of his circuits with the Prius. (Ironically enough, he was very vocal against the Prius until he had a chance to drive it and had a remarkable turnaround.) Anyway, his in his Prius I review he got 75 mpg (3.119 L) and I seem to recall his first Prius II drive was in the 80-90mpg range. Just an FYI.

ok but here in the EU the civic ( 2.2 diesel new model ) is rated
5,26/100km agains 4,29 for the prius

The civic gasoline baseline and clean diesel are manual transmissions. This is not an apples to apples to comparison to the civic hybrid or the Prius which are automatic transmissions. Automatic transmission would decrease fuel economy 5-10% for the civic gas and diesel versions and the cost would be $500-$1000 more for this feature. Diesel is more expensive and less available than gasoline in the US last time I checked. Where is the savings?

Just to make sure I am clear, you are doubtful of the bigger gap between the Civic ratings and the Prius ratings? Not sure why that is, but I can think of a couple of reasons. One, not sure if the 4.29 is the Prius I or Prius II, but if it is th Prius II, I only found a number for the Prius I. Since it is my impression II is better than I on mpg, Wayne's numbers for II could be in the 2.9 (80 mpg) to 2.6 (80mpg) range (guessing from my memory of one of Wayne's post several years ago).

An additional reason could be the diesel being a manual and Wayne being able to employ more of his tricks. I am pretty sure he stated that he could get better mpg with the manual Insight over the CVT Insight. Regardless, the Prius still has better mpg compared to a vehicle that is a size smaller.

Not believing it won't make it any less true. Where Xcel is concerned, all bets are off. He is the one that taught me how to get consistent 60+ mpg tanks on my '99 Saturn SL2 with a 5MT and, in the warmer weather of last year, a string of 80+ tanks with my '07 Prius.

Right you are.

Average german drivers average a 6.37, with a low of 4,98 to a max of 10.7 l*100 km

Check it out for yourself! Overview: Honda - Civic

But if you drive it like a hypermiler, well, I too got 3,2 l*100 km!

thats because in germany there is no limit on the highway and the guy in this US civic dit not go past 96kmph

when i do that in my prius i can hypermile to

Hi all,

We have the 6 drivers now. Thanks for the interest. I will start a thread about the trip as we leave for the shootout on Wednesday.

exiting

Please, keep up posted!

I. pretty sure that the guy doing 4,98 is going pretty slowly.

My hypermile record is 3.2 on one tank.

a ok so thats where AL the traffic jams in italy come from there behind you:heh:

Always, being the only italian respectinfg the speed limits!

BTW you don't mind my wife joining your Dutch chat?

she wil be the first member hahahah and not dutch speaking nor writing?

Your forum does not send the confirmation email and therefore she is stuck.

And yes, she knows Dutch, not that she is Dutch, but you Dutch have left influences around the world.

not getting the conformation email?

mm i am going to check that

You've probably figured it out now, but CleanMPG is a group that promotes hypermiling, I believe it was started by Wayne Gerdes, who's been featured in the American media from time to time. They are not claiming that their numbers reflect the average driver (which is what most group and government ratings are for, at least in theory), but instead what is possible with the vehicle.
In a standard car, one of their main tricks is to turn the car off, with the transmission in neutral, while driving (coasting) down the road (forced auto-stop or FAS, as they call it).
