First WFEC was a huge success (http://www.cleanmpg.com/.phpforums/showthread?t=12620)!

http://www.cleanmpg.com/photos/data/501/2008_Toyota_Prius1.jpgAuston Hensley – CleanMPG (CleanMPG.com) – June 22, 2008

The history of fuel economy goes as far back as cars do. Cars have always had the need for fuel efficiency to keep costs down regardless of who it was or whatever was being driven. Fuel economy championships date to the 1950's during the Mobilgas Economy Runs and similar events being held today. Where better than to demonstrate what can be done with a vehicle in the best possible conditions in any place other than Indiana, the home of the Indianapolis 500?

This is of course, a story told through my own eyes.

The World Fuel Economy Championship held its first meeting over the weekend in Elkhart, Indiana, at Larry Trowbridge's (Diamondlarry) place. I arrived with Jud (Bestmapman) in his Prius-II. Wayne B, Larry, Hobbit, and others had already arrived and were setting up tents in the backyard to spend the weekend.

The rest of the evening was pretty much spent setting up the tents and meeting everybody. I think it was just spent swamped in various bugs and barn cats who'd eat anything. Larry has a Beagle and several cats, as well as a variety of older vehicles laying about. Also, we found out that he and his son have the best commute imaginable. There's almost no traffic lights of stop signs, no traffic, just about as flat as it could possibly be, and if there was any traffic it was all country roads so they could go around. We spent the rest of the night in lawn chairs in a circle, with a bright light well away from us to attract the bugs away. And then hobbit got right next to the light...

At about two in the morning, Wayne arrived in the MDX along with a whole FSP-full of people. I, half-awake, walk over and ask what kind of car it is and the response I get is 'It's a fuel sucking pig' :P

Without any further major incidents, the rest of us had arrived by the next morning. As soon as enough of us were awake, we then spent the next two hours talking about various small things, none of which were important. We were hungry. The move that finally got us moving though was when I cranked the starter in the MDX, immediately getting everyone's attention. LOL

That is, after we got some McDeath for breakfast.

And then once breakfast was done, the fuel economy runs began. I was the official score-keeper, which also became the guy who makes sure all the cars are out there, and who's supposed to be driving, and who's next. I spent most of Saturday running around like a chicken with my head cut off.

For the Priuses and FEH, they started halfway down Larry's driveway, left on the road, and then another left up the hill at the stop sign. We drew lots on who would go in what order, and three Priuses and the FEH were all out there at any one time. The Insights started at the top of the hill with someone to push, in order to get it rolling down a hill and then pop the clutch.

The Priuses started with a SoC at 70 and the FEH at 52.4. The Insights had their IMA functions disabled and the packs fully charged. All cars were sent off at three to five minute intervals when the road was clear of traffic.

The course was 16.1 miles round trip. This consisted of four miles south along County Road 1, including three stop signs. Then we'd turn west along County Road 40, with a posted speed limit of 50. We'd go another four miles to a school where we'd turn around and come back the same way we'd come.

As Saturday went on and the results began coming in. During this time, Laurie in a clinic with Wayne posted a 1.1 L/100km (213.8 MPG over 6.2 miles!)

The highlight of the day had to be this, though: as I was making my run in Blue Swayed late in the day, I drove by a house with kids playing in the front yard. And as I rolled past, < 15 MPH for sure, one of the kids shouted out loud "Why can't those cars go faster?" :D

Now that I think of it, this event would look really weird to an outsider. The same seven cars, all with out of state plates, going back and forth on a road in front of your house, all day? And they never do more than 20 miles an hour? That's probably on a local Northern Indiana forum somewhere by now. "Strange sighting in Elkhart today" or something.

The world-record holder of the best miles per gallon in a hypermiling championship now belongs to Wayne (xcel), who posted a 1.1L/100km (213.8 MPG) over 16.1 miles in Sean's Insight, Blue Swayed.

The FCD reports 15.7 miles/25.2 kilometers, probably because of so much FAS'ing.

*1 = One of the Priuses read distance driven incorrectly, skewing final MPG by 3%. These are the corrected numbers.
*2 = Thunderstorms happened during these runs, lowering the final mileage.
*3 = At some point on Saturday one of the Insights had a brake problem, and it dragged, lowering mileages by a third or more.

All in all, I had a great time meeting Wayne, Chuck, Andrew, and the whole crew. I pray they all have a safe return home and that we hold another meeting like this as soon as possible.

Basically I'm just letting everyone know I'm back in Dallas safely.

My first flight to Chicago on AA was in 1989 at 700mpg due to a headwind - my biggest gas guzzeling trip ever...explaination...I was between jobs and a recruiter sent me on an interview without really screening. Over the phone they could have found out my database experience did not cover DB2 as the qualifications required. That cost the gas on a round trip from D/FW to O'Hare and the recruiter $800.

Would have liked to do more, but the "must do" things were accomplished along with the pleasure of meeting many of you for the first time. :)

I tell you what we can do--I could shoot some video while in a Prius or other hypermiling vehicle at the next meetup on the 5th? And then just have the driver explain what he's doing? Pretty inexpensive since the camera is already paid for and I still have 45 minutes of tape. :)

I've added Bob's score on the Prius to the list (perhaps I was AWOL when he came in or I was on my Insight run?). Coming tomorrow are the scans of the original score sheets and a few of my overall comments now that I've had a couple days to sleep on the whole experience.

But all in all it was a hell of a time even if I was running like a chicken with my head cut off and had to watch Wayne go about 2 MPH up the first hill in his Prius :rolleyes:

Wow! Talk about a blast from the past. Thanks for bringing back the memories Andrew. Anyway, one of the vehicles that didn't get mentioned in the official stats was my son's (CobraPond) '99 Saturn SL2 5-MT. If I remember correctly, he did 88.5 mpg on the course. There were some modifications to the cylinder head and the valve timing had been tweaked to lower the rpm of the torque band however, the driver is really good by himself.

Initially I didn't look at the date, but when I saw "Wayne arrived in the MDX" I knew it had to be old.
MDX is a very nice vehicle of course- quiet, comfortable ,decent enough mpg for 4400 lbs and 188."

You Guys and Gals are amazing, I was sent here from the Solstice forum because my shifting at or below 2,000 rpms and only doing the speed limit would get my 2.4 gasoline engine around 35 MPG. If I had that extra 6th gear I know I could hit 40 mpg's

Boy I'd like to find a way to get that even higher.

I coast down hills, gently press on the gas, and always try to use my cruise, never going over the speed limit. well one mph.

It's hard to imagine many of us even achieving those MPG figures in extreme cold Arctic temperatures... so, it definitely takes a certain driving style to achieve a mileage that low. ;)

Welcome to CleanMPG, Lee.

To start, read the CleanMPG Primer (http://www.cleanmpg.com/forums/showthread.php?t=19408), which will take you through introductory articles.

Then you can introduce yourself in the Welcome To CleanMPG thread (http://www.cleanmpg.com/forums/showthread.php?t=39), or start a new thread in Start Your Journey Here (http://www.cleanmpg.com/forums/forumdisplay.php?f=38) if you have any questions. Tell us about yourself: the vehicles you drive, the area where you live, your driving patterns (how many miles, what the traffic's like, stop-and-go/interstate etc) and, of course, your current mileage and any fuel-saving techniques you're already using. We won't press, but feel free to add any background information about yourself. We're a community of people.

There are also vehicle-specific sub-forums where you can ask specific information or share the knowledge that you gain. Posting in those sub-forums will get the attention of other owners of the same or similar vehicles.

It helps us help you if you edit your profile (http://www.cleanmpg.com/forums/profile.php?do=editprofile) and add details of your vehicle(s) (Year, Make, Model, engine size and transmission) and your location (a region will do) so that it will appear in the right-hand side of your post headers (as the Prius, Civic and Maine appear in mine). Techniques depend so much on the car, traffic, terrain and climate so it will save additional posts asking and providing information.

When the tire pressure is set at 80 psi - did you limit the top speed to 20 mph for safety reasons or do you believe that the tires could go at a higher top speed? That is - was the 80 psi setting for the Championship driving environment only?

How did you get the Prius SoC up to 70%?
Was that for just the first driver or was the SoC reset to 70% for each driver?

Hi Walter:

Burst pressure on today’s tires are many multiples of max sidewall so you do not have a safety concern here.

Everyone took off with an initial 70% SoC in the Prius’ with both initial and final SoC recorded in order to balance the results. You can force charge a Prius to 70 + %.

Yes Walter, I hear a Prius can be force charged to about 83%.;) I have had multiple 10's of thousands of miles both local and highway at 80 psi (occasionally higher) with no safety issues and no uneven wear.

Thanks for your quick response. I'm a scary cat so I have
been only gradually upping my tire pressure ( I'm currently
testing out 50psi/48psi). My concern is not that the tire air
seals will fail but that road handling/braking performance
might degrade or change in such a way that I am unable
to compensate for it. I am using stock Yokohama Avid
S33 ( max sidewall is 44 psi).

I read that Toyota engineers forced the SOC up by
stopping from a very high speed. Is that how you forced
a charge on the Prius or did you use a battery charger?
Thanks

Wowsers!

Thanks. As a hypermiler neophyte - the safety issues is my
own driving skills and whether I respond correctly to a given
driving condition which is why I am only slowly upping my
tire pressure so that I can get a feel of any difference in
handling. I am using Yokohama Avid S33 on a 2010 Prius 3.

Last December, I had upped my tire pressure
to 50/48 psi. While it was raining on a downhill section of
a curved crowned asphalt road (Nicholson Ln, North
Bethesda,MD) an SUV merged in front of me and
shortly afterwards stopped to make a left turn. While I
had more than enough distance to stop on the wet
downhill - the Prius shook/vibrated briefly as I braked
hard from 35mph to 0mph. I had stopped about 20 feet
behind the SUV so I had enough distance behind me
but the vibration suggested that the ABS was operating
because I had lost some traction. After that incident,
I dropped my tire pressure to 44/42 psi. With drier
weather, I have upped my tire pressure back up to 50/48
with a keener focus on having a longer stopping distance
when driving on wet roads.

To answer your question about how the Prius' were force charged, it is done by putting it in D then, while holding the brake pedal down, you press on the gas. A couple of years ago, I ran an experiment with my Prius where I left home with some recycling stuff and when I got there(approx 7 miles away), I forced charged to the full capacity. On the way back, I had 255 mpg showing on the Scanguage. When figuring in the fuel used while charging, it came to 103 mpg for the round trip. For me, this was almost a wash since that is about what I could usually do.

Run that by me again! Force charge a Prius by applying the brake and hold the throttle down? Are you at a stand still when you do this and how much gas do you give it?? H

PaleMelanesian
06-24-2011, 09:54 AM
Don't bother. It didn't actually save any gas. It only gives a huge number if you ignore the gas used to force a high SOC.

Yes, that is done while stopped. Usually 1/4 to 1/2 throttle is about right for that procedure.

Don't bother. It didn't actually save any gas. It only gives a huge number if you ignore the gas used to force a high SOC.

Andrew is right, it doesn't save any gas really. As I mentioned earlier, at best it's a wash/break even situation.
