Lol, I'm sure you're right, but you're missing the intent of my post.

Since I don't drive to work on a closed course every day, those track numbers (although freaking awesome) are kind of meaningless to me. I want to know what that Centurion will do in traffic, tank to tank, in the world where all of actually drive in every day, and I've been dying to see some fuel logs for it since I joined ecomodder

A buddy mine and his dad are getting ready to build one, I already sent him the link to the posts here.

I drive to work almost daily with Centurion. There's an entire college and towns that are witness to it and it's mentioned in the press release. The 30 mile out-n-back closed course to work I drive on is likely much different than each person's closed course driving route so the numbers and route is likely not representative of your own drive. So, are the numbers from this drive even relevant? Your drive is not my drive so where's the relevance? When car racer's race, do they combine results from two separate/different tracks on on opposite sides of the country the same day under different conditions? No.

The GGP course however is a constant for everyone who is willing to participate on said day. so I believe it makes for a better comparison. There are less variables there and we all competed under the same conditions. If my numbers were artificially high - then so should all the results be.

I'd like for those who actually attended the 2014 GGP to come forth and admit that their mpg numbers on that day were way out of line as Sendler is suggesting. Any takers?

Following the thread, Centurion has consistently been subjected to changes - changes that have affected it's fuel economy - hence the long pulse-n-glide two year thread. These changes take time. Each run is mostly exclusive to the changes made and therefore not consistent to one completed/no more changes project. In fact, Centurion is nearly six months ahead of all ecomodder postings to allow time for testing. Right now, it's not even the same car it was during the Green Grand Prix - "major changes" were made starting the week after the Green Grand Prix. I've set a couple more targets for Centurion that may be out of reach but I'd still like to give it a whirl. So, until a final build is completed, a fuel log is not on the list although I have indicated numbers along the way, be it on the car's fenders or in text.

Can't wait to see the fuel log when you complete it!

I think I've checked at least once a week to see if you've started one since I've been coming here

Personally, I don't care whether Jerry gets 185 or 187 mpg. The difference is probably a couple potholes. He's so far beyond the rest of the field...

There are ways to get more accuracy and resolution than the methods used in the GGP but it is beyond the scope of the event.

Sendler's original argument is valid but has very little to do with what the GGP is trying to do - showcase the cars and drivers. And with Centurion's small, cylindrical tank, the volume change is much smaller than Sendler's napkin calculations. If there are any doubters, they can meet Changzuki at next year's event and measure the mass of the fuel tank before and after along with the use of an accurate GPS. This was the method used by the AutoXprize and should be more than enough to verify Centurion's 200mpg status.

Look at the previous year. C. Michael Lewis did 130 mpg on the track in a beat up old Insight. Using every competition trick in the book no doubt but nonetheless, that is what he posted. Competition conditions don't represent daily driving.

We had to wait for a tractor operator to come pull him out when the freshly grassed field sank everyone to the axles during the hailstorm that came through while we were having dinner.

So why wouldn't you want to keep a fuel log all this time which Ecomodder has conveniently provided right here to find out what economy you really get?

Well thankfully this year's Green Grand Prix Stage 1 was not an off-road competition. I had no problem staying on the track...
.
WAIT - WHAT IS THIS!!! Oh look, it's not just that one Sendler: Reviewing this year's footage from Centurion's on-board cameras, clearly the red insights are not suited for the rigors of the Green Grand Prix. Bwah-ha-ha-ha!

Sendlers original argument of volume change / thermal expansion is irrelevant to Centurion's fuel tank. There is no heat returning from the engine to the tank as he suggests. Zero - zippo - goose egg. The only heat the fuel tank could've absorbed was from Sheepdog 44's head since it was right behind him.
