Hi chinup. Great to see you post again. Enjoyed our conversations at 2016 Hybrid Fest.

I can't quite agree on the FAS circuit thing. I think that using the FAS circuit makes a significant difference, but not sure of exact percentage.

The reason it matters is that when you "key off" you are losing the benefit of some of those "free" coasting 100s of feet. Seems to me that one can coast a 100 feet or more while the car goes through its engine off sequence. The odometer doesn't accumulate distance when the key is off. Since fuel economy is distance/fuel, the distance number becomes diminished. I first noticed this at one of Mike Dabrowski New England contests, while using key off, when my accumulated mileage came in short of the actual course distance. How big is the error - I don't really know, but since it is taken out of the "free" distance I think it is significant.

As Lyger says, it is all a game this hypermiling. Like any other game, some of us enjoy it while others think it useless. AND, circumstance of terrain, temperature, etc. vary so widely across this country that comparisons between individuals is really tough. It pays not to get too excited unless it is a regulated competition over a fixed course with some rules of competition.

Hey Jim nice to hear from you. I agree I would have lost something maybe a mile or so a gallon. I only used FAS between 4-6 times per 50 to 60 mile run depending on if I made the lights, so in my case it probably wouldn't have been too bad. No battery and used no FAS on the fixed course at insightfest. I'm coming for ya Jim! lol

 

[mrchinup]

I agree with Jim. "Hypermileing" for me is entertainment.
Maybe "One of these Days" we can have a 100+ mile MPG contest?
Instead of the "short" ones.

OK George lets see a picture of your LMPG.
Glad to see you are still around.

Willie

Hey Willie, nice to hear from you. We were down in Yuma for 11 days visiting an old friend and warming up over Christmas. Wish I had your phone #, Would have loved to stop by. A 100+ MPG contest would really even it out, specially if we had some nice hills. Right down the street from me would be the perfect place, Lake Mead Rec Area. I don't think anyone would break 100mpg.

My lifetime mileage was never changed, I bought it at 235k. Then Scott put a newer engine in it, might have 260. I should reset it. Hope you're doing great. Would love to see your area.

Yeah that was a very good number. For those who argue it can't be true, that particular course was very flat, very rural with very little traffic, and the day was hot. There were also some opportunities for FAS and key off coasting. So conditions were near ideal. The "fully modified" winner set a mark of 130.1MPG , and I think he left at least 10MPG on the table due to a weak battery.

All numbers were verified by independent observers at the course end. But, one has to remember this was all at slow competition speeds, using lots of hypermiling technique, over a short 20 mile course.

They should do the contest like racing. Modified and non modified ect. Really if none where modified that way its the skill of the driver that counts

It WAS done that way. Go to post #649 of this thread:

http://www.insightcentral.net/forums/hybrid-socials-events/85338-insightfest-2016-a.html

for a complete list of class winners. There were several entrants in each of the classes.

BTW, the "they" in this case was the pronoun "me" since I laid out the course, wrote the rules and supervised the competition. You can PM me for specific questions if you have any. I was looking to the modified winner Joel to peg the 150MPG gauge, but he had battery problems and could not extract enough electrical energy over the short course to zing the gauge to the top.

Nothing "real" world here - just fun. Remember that this was a competition course, laid out to maximize the results - since hypermilers like to see big numbers

 

[mrchinup]

Jim you did a great job laying out that course. Couldn't have been any better.

 

[freezin4]

Like Jim mentioned there are SO many variables (even on the same course at the same time: battery condition, tire condition and pressure, engine wear (miles) etc

Me in the Insight

You are obviously doing pretty nicely to raise your lmpg from the 47's. Very difficult to do on busy roads.

Much discussion on whether to reset or not; you should consider resetting your lmpg. As an Insighter said to me some time ago: track your miles. I took his advice.

btw: would like to see the pic with a 6' 8" person behind the wheel

You asked for it Mountain Driver. My head doesn't quite touch the headliner. I did take the back spring out of the seat, but did add a piece of foam camp pad so I think it offsets.
Sorry it took so long, but even with my long arms I could not manage it and pose behind the wheel.

 

[gilbertguy]

The real trick is not sitting in the car but getting in and out of it at 6' 8".

 

[S Keith]

Heh.... 5'10" and 270# presents a challenge too...

Room to spare. You still have space between the dash and your knees.

Always amazed at the how the car 'fits' even large folks.

 

[Lyger]

maybe he has a life size shoehorn.

Best i have gotten on a run so far.

Hello!
pfnr37 shared an album with you.

This isn't as impressive as many of you ubermilers, but it's pretty good for me! Car is stock, just keeping it in lean burn avg maybe 63 mph, 56-70 through the trip. I really felt there must have been a tailwind.

 

[Mountain driver]

^ Nice mpg for stock. Careful, the mpg bug is very contagious

Thank you

Thank you for the great post, 1st time poster

Aiming higher

Hi folks.
I've had the car a while now and can pretty much guess what consumption I'm going to see on a trip. The warm weather (for the UK) recently means I can achieve 95-100 on a longer run, but this is really just driving to a target. On Monday I had to travel from Milton Keynes to Telford on business and asked myself "why I don't shoot for a ridiculous target for once, say 120mpg?"

Job done

I was on time for the meeting too. What an amazing car.

Nicely done! Now see if you can get the whole tank with that number!

Congratulations to NASA for having the highest mileage Insight! With only 54 million miles on the odometer, it's good to last for many years to come!
I'm not too certain of the efficiency though.

 

[samwichse]

Maybe that far as the crow flies (in space!), But the actual distance traveled was 301,000,000 miles according to NASA's press kit.

Haven't found any info on fuel mass for the first and second stages to do an MPGe calculation, though.
