I live in a depression so this pic show slightly inflated numbers. The tank is at 88.5 displayed, measured at the RTP. This needs to be further adjusted down to about 85.4 to match the difference between the average my car displays and the average I calculate at the pump. I'll take 85 in a HCH anyday.

Truly awesome LD. Your best ever? What has changed from last year to this year?

Wow,

That mpg is awesome, how many miles on the tank? What are you doing differently? What kind of speeds, terrain, temps, weather(rain etc) have you experienced. This is truely amazing, What was your best previous tank? I think Dan's best tank (not including the marathon) in his wife's Prius was something like 86.6 over 1007 miles. It looks like you may overtake that mark. Way to go!

Dennis

Wow Dennis! You seem to know my stats well. From the picture it looks like he has 66 miles on the tank so he has a long road ahead. If he can beat my 86.6 tank then I might have to borrow the Prius back from the wife to shoot for 90.:D

Hi Lakedude:

Who needs an Insight?
___You do.

___Insight’s and CVT based HCH-I’s have done even better then the screenshot above in fact :D

___Good Luck

___Wayne

Not suprized to see a reply like that. :D

Win-win situation....

in the future choosing between 5 spd and CVT will be even harder

Dan, best ever for sure.

X, I guess I deserved that. Who has a CVT based HCH that is better?

How did I do it?

Well nothing new really. Good weather, No AC, high pressue in tires, leaving early for work to avoid traffic, No extra short trips what so ever, No high speed highway runs what so ever, Cresting hills on 5 lane 55mph highway at 25mph ICE off, Really pushing the ICE off times during the FAS, Quicker shifting into taller gears, Knowing route ever better, Not giving two spits if I'm holding someone up behind me (There is never a spot where I'd hold anyone up for long, they can just deal with my wussy footing for a couple of blocks), Luck with bottom of the hill stop lights, Luck with traffic and road construction, Luck with wind (usually my one big disadvantage), Really pushing the tallest gear posssible at all time, and Keeping an eye on the SOC all the time.

Hi Lakedude:

___Tom’s CVT based HCH was over 100 mpg’s for > 40 miles but we had to come home on the Interstate due to running out of time. We ended up > 80 after a 150 miles or so IIRC? I wish I had a camera that day :( At one point, she was showing > 120 mpg’s in fact! RJ had his MT based HCH over 115 mpg’s for something like 30 or 40 miles as well?

___Good Luck

___Wayne

Well from what I remember about when RJ did it, is was a route that was particularly friendly, like the Prius marathon route. it was not a route to work. I think LD shoud get credit for that at least. My best was the 86.6, which was largely my daily commute. Hang on LD and give me a reason to retire the Del Sol for a few weeks.:D

Thanks Dan,

Fighting a headwind today has the tank at 88.1 displayed. My commute is about 17 miles one way. I could do 90mpg easy if I drove my commuting route back and forth with a warmed up car and similar wind conditions both ways. The wind is usually strong (10-20mph) in my face going to work in the day but it dies down at night by the time I go home(0-5mph) so the net result is about a 7mph headwind all the time.

88 displayed is going to translate to about 85 calculated (what I actually post) so 86.6 should still be safe (darn it).

Don't give up so soon!

My drive is 25 miles each way and yes, I agree that doing the round trip with a warm ICE makes a huge difference. I actually tried that and was in the low 90's. Cold starts really hurt, wHich is another reason that your tank is notable.

By the way, the winds on my commute are generally calm in the morning and strong (10-15mph) on the drive home. Sometimes headwinds, sometimes tail winds. Overall it is a wash for me.

Just wondering how much longer (in minutes)your commute is vs. "mild" hypermiling, say no higher than speed limit but only going 10 MPH under on the highway at hill crest, and then still using all other FE tricks, DWL, DWB, FAS, p&G, etc. 25 on the highway is a bit farther than I would go, I would be afraid to get rearended. Also, how much of a mileage improvement are you seeing by going from mild to extreme hypermiling? Still if you can pull off anything near the mid eighties, I commend you, just keep your eye on the rearview when you are at 25 in a 55.

Mild hypermiling only adds about 5 minutes to a 25 minute trip. Record tanks like this one add another 10 minutes or more, mostly due to hilltop slow downs during a FAS. When I hit 25 on the 5 lane it is midnight so there is not much traffic and I do watch the rear view closely. If a car comes up I'll hit the flashers or a turn signal.

During a record tank I crest the hills in the subdivision ICE off with just enough momentum to get over at as close to zero mph as I can get. Sometimes I don't make it and need to restart or push the car. That is where most of the extra time is, creeping along at 2-5mph.

Yes, some of this is a little silly. Mild hypermiling saves time and doesn't use that much extra gas but every drop counts when you are gunning for your hero Krousdb.

Sorry X your Insight is out of my league and the Accord is no challenge.

PS

Cresting hills slowly is a real art. Mild hypermiling is easy, if you FAS too soon you still have plenty umph to get you over. Extreme hypermiling is much harder because at under 20 mph there is not much energy left in the car so split second timing is required to kill the ICE at just the right spot. It is a new fun game to play. If you lose you gotta get out and push!

Hi Lakedude:

___The heavy - semi-lux - and far more powerful non-hybrid Honda Accord can do some damage to the EPA when pushed as well. If only my commute was more conducive to extreme hypermiling across the entire route :( E/T is ICE-On time in case you were interested. Maybe I should be looking for a less Fuel Efficient car myself?

My mileage is too high, what can I do to bring it down? (http://www.insightcentral.net/forum/viewtopic.php?t=4965)

Lakedude that's quite a screenshot!

I think you've more patience than me.

At 3:00AM, on a empty-nearly abandoned road, in the middle of a 2 mile FAS I roll across a hill at 25-30MPH before rolling back down the other side...

It's those times when I wish I had my imaginary fold down pedals for that extra push!

wow, that is awesome. a 2005, right? manual or CVT? i managed a 63.1 overall for my last tank, but i don't think i would ever see 90 on there........

Laurie, thanks, 2005 MT yep.

X what car is that screenshot from? Your Accord? Holy Crap! How you do that??!!??

BTW crappy wind disadvantage has me down to 87.4 at the RTP. I really got ripped off today. Very windy going to work into the wind, dead calm on the return trip.

Lakedude,
I echo your comments on that screenshot from Wayne. Was that an Accord and how is that accomplished?
Keep up the good work on that tank, and for comparison what was your best tank for a more mild hypermiling (say one that could be accomplished more long term rather than attempting to break your personal best tank.)

___WayneI hate you, fantastic job BTW. Is 99 the display max?

Mid seventies is pretty easy to hit in the summer with a mild effort. Mild hypermiling still has me doing 40-55 mph in a 55mph zone, only hitting 55 on downhills. About 2/3 of my trip is in 35-40 mph zones anyway, only 1/3 is at the 55 mph limit. Blasting around a 70 mph has lowered my average to the low sixties. If I never went on long trips at 70 mph my average would be in the high sixties, maybe even low seventies.

BTW here is what I'm calling mild (to some people even my mild effort may be considered extreme):

DWL, FAS (lots), 40mph, no AC, drive like brakes are broken, conserve momentum, no warmup, face out parking (work end only, nose goes into garage at home for safety), high pressure tires, no short trips (sack lunch), and no high speed trips.

Extreme hypermiling adds some PnG, running a stop sign or 2, slowing down to 25 mph in a 55 mph on hilltops, slowing down to near stop in subdivision on hilltops, and pushing if I don't make it.

Nice work, lakedude :) What do you think, is it time to add some bicycle pedals to that thing or what? I can't imagine actually getting out of a car and pushing...

Wayne (do you prefer X?),
What is RR and SB, I couldn't find these in the glossary?
Dennis

Nice work, lakedude :) What do you think, is it time to add some bicycle pedals to that thing or what? I can't imagine actually getting out of a car and pushing...Pushing is punishment for not timing the FAS properly. The idea is to not hafta get out and push.

I'm not talking about pushing a car for blocks BTW. The car is only being pushed for a couple feet to get it off the top of a hill and only when I goof on the timing of the FAS (almost never but I have pushed once this tank).

can't imagine actually getting out of a car and pushing...


trust me its worth it, with high tire pressure its effortless, I can push a 2400 pound car with my left foot sitting in the car! but maybe 3000 pounds could be a different story...

there are some cases i get out of my car and push it with teh door because i can use my whole body to push it, piece of cake and the car rolls too fast! Now if only i can bump start in reverse ;P

Hi LD:

___Max is 99.9 mpg.

___Dennis, not really. Wayne or xcel is better on my eyes ;)

RR: Ridge Riding
SB: Smart Braking

___Good Luck

___Wayne

Xcel,
And smart braking is what? Similar to DWB?

Dang! I thought I was going to be able to lock up that elite status in a week or 2. :D

Called it a tank at 303.1miles. 81.6 calculated was a little disapointing (was hoping for 84) Sorry for the crappy pic, phone cam.

Good job lakedude, very impressive. How much of that 303.1 was human powered? If you are interested in a muscle/electric hybrid you might check out this sight www.twike.com/

nice! Thats close to double what I'm getting right now.

As far as teh twike goes sno779, that looks kind of interesting.

Awesome! You beat Dan K's best non-Marathon tank (86.6 MPG by MFD) if Dan's Prius is like mine the MFD tends to be 2 % high vs calculated MPG long term, so if we adjusted that figure down by 2 % it becomes 84.9 MPG. What long term difference do you see between lmpg by MFD vs lmpg calculated by hand for your HCH? Is Dan going to take back the Prius from his wife? Or will he crank out an incredible tank from the del Sol?
Maybe Dan will "take off the gloves"? The competition could be interesting and it would get even more interesting if rbarlow jumped on the bandwagon. Why did you fill so early, I always like to try to stretch out an impressive tank, I suppose it is tougher to do that in the HCH because you would have to keep up the mileage over an extra 350 miles vs. a Prius II because of your larger tank. Maybe someone can create some fair ground rule like the tank should be over x miles to be considered exceptional (Dan's tank was around 1000 miles I believe). For myself I can almost get 70 mpg over 650 miles, I am not in the same league as you and the other elite hypermilers, but I have made some progress over the past few months.

Today I checked how many steps it took pushing to get the car rolling and counted 6. The car was pushed perhaps 5 times for 6 steps at maybe 3 feet per step for a rough estimated total of about 90 feet out of 303.1 miles. That makes 0.0056% pushed or 99.994% not pushed

DennisThanks!

I normally stop after 300 miles as has been my habit ever since my 1992 Ford Ranger's fuel gauge gave up the ghost. Since the fuel gauge on the Ranger was broken the trip meter functioned as the fuel gauge. 300 miles was about the max safe range in the Ranger per tank. I know the hybrid will go 3 times that far but it makes me nervous whenever the mileage is over 300. If you check the database most tanks for IMLC are right around 300 (average tank = 363 miles), this is nothing new.

Currently my lifetime (trip B) is at 65.1 while GH has the calculated lifetime at 62.5 a 4.16% difference. This was 3.3% last time I checked? Perhaps the lifetime is not true lifetime and skewed twards more recent tanks? It is cool to even be in the same ballpark as Dan!!:) (he is one of my heros)
