Hypermiling

Are you guys aware of this? A coworker comes up to me the other day and asks if I have read anything about hypermiling. "Oh, you mean when people fill up their tires with oil and draft behind semis?" Not exactly. So I read this website. http://www.hypermiling.com/ Seems like I can adopt some of those habits easily, maybe improve my mileage. I've noticed it REALLY makes people angry when you coast up to a red light! I'm getting better at coasting to a corner, sometimes even hitting it exactly right so I don't have to brake! Jackrabbit starts are a little problem of mine, but I'm getting better. Having learned to drive in an icy environment, I'm already not much of a tailgater. And I'm sure my father is rolling in his grave: he was always the enforcer of complete stops at a stop sign- the kind where your car rocks back with the force of coming to a dead stop. He'd watch me leave out the window, and if I didn't make a full stop at the stop sign on our corner, I'd hear about it. 35 years of driving later, I still hear his voice every single time I stop at a stop sign. But now, I don't quite make a complete stop, unless I spot law enforcement near by. I'll even roll right through 'em if I can see for a long distance, out in the country. Not DRIVE through, but just apply a token amount of braking. I fell like a sloppy driver, but I'm improving my mileage. I love the game of coasting up to a red light, applying just enough brake to not stop, so I can just keep going when traffic moves when the light changes. So, I know you can save a lot of money by driving the speed limit, or under, but I just can't do it. I typically set my cruise control about eight miles over. People driving the speed limit infuriate me- I'm not sure why. I know, in the long run, I only arrive minutes before they do. But I _like driving fast! So maybe hypermiling will offset that a little. http://tinyurl.com/y8xeuf That's a cool article about the King of Hypermilers. Anyway- food for thought!
 
The cost of gas is hitting us all. We in the UK pay a lot more than most of you, so the more mpg the better. I've recently changed my gas guzzler for a little run about. I thought I was going to be left behind on the open road, but no, everyone is driving that much slower nowadays to economise as much as possible. I now get between 40-50 mpg, and I'm still trying to improve it...LOL
 
Yeah I've heard of hypermiling. I already try to coast to stops and such, and I take off slowly from stoplights--I'm a very laid back, non-aggressive driver, actually. But I can't stick to the speed limit, either. :awcrap: Just can't. Around here, people often drive 20 mph over the limit. I feel like I do well when I can limit it to 10 over. On the other hand, I've used a motorcycle as my primary form of transportation for 14 years, and the bikes I've had the longest have gotten 50mpg.
 
:nope: -1 for you

I'm sorry! I don't mean drive right through- I mean coast up from half a mile away and apply token braking when I can clearly see there is no traffic in sight. At 6AM, not rush hour. Yes, not a stop, I know. My gasoline bill last month was $400! Braking turns gas into heat! Now I feel like every time my car is stopped, I'm burning money.

I think it's called a "California Stop" LOL.

What really gets me is that it takes $4+ gasoline to make people quit wanting these big Avalanche and Escalade type-cars and begin to take these steps. I see all these new cars touting 35 MPG in their ads, yet I remember those Geo Metros in the early 90's got like 50. What happened that 35 is now considered good?
Here in Eugene the city is real progressive and tries hard to be a "green" city and there is great bus service. It's nice to see a lot of the city employees driving Prius and in the parks department they actually have a maintenance cart that is towed by a bicycle for litter patrol!
I've been struggling for a bit financially and I am sort of just staying at home a lot unless I have a job to go do. I walk or ride my bike to the grocery store and I do pay more attention to my driving, I am guilty of the jackrabbit starts sometimes.
 
I don't do any of that stuff - or plan to - the cost of one citation will FAR outweigh any fuel savings.....lol. BUT, I'm not one that will break traffic regulations (or be a discourteous driver - such as doing 20mph under the posted limit - IF others are around) to save a few cents on fuel. I'd rather stay home and keep the car parked before doing that. :) Nor do I speed. People that do and tailgate do NOT enjoy my responses. People that drive excessively fast have no right to complain about fuel costs - neither do people that have jacked up large trucks that they have NEVER taken off of the road or used to haul anything! Ditto on the people with giant SUV's that have one kid and buy 2 bags of groceries at a time. Face it - Americans are rather glutinous, and we confuse needs with wants. We WANT to drive to the other side of the country for a vacation (that is not a need), but we think SUFFERING is having to give up that vacation because of fuel prices. Bull puckey - that's inconvenient - NOT suffering. "Suffering" isn't having to eat out a little less, taking a few less trips into town, seeing a few less movies, buying a few less snakes, living in a slightly smaller house, shopping at Wal-Mart instead of Sears, or even having to eat store brand instead of name brand foods. NONE OF THAT IS SUFFERING......except to most Americans. Heck, any of us posting here from a home/personal internet account not necessary for work can't be actually suffering TOO much, can we?

I'm with your dad - 3 second stop or I'll take your license....lol.

Not to mention the cost of a new starter with all the extra turning on and turning off you are doing to the engine. Don't even get started on grinding up the gears in the transmission. How about needing to replace tires more often, which will be needed when taking turns faster . . .

I agree, short term they're saving money on their mpg's, but in the long term what extra costs are coming up from extra maintenance needed on their cars. :shrugs: Plus, don't forget the advocating of breaking numerous laws of the road . . . explain that to my son who just took driver's training and will be testing for his drivers license. (Don't get me wrong, I've done a California stop as well as a few miles over the speed limit etc. . . . that doesn't make it right.)

Interesting topic for sure, but not my style either. :)

I've been trying to do a lot more to conserve gas, even though I drive a Toyota Prius. There's a monitor in the dash that lets you know when how you're driving is recharging the battery (coasting is a big one!) along with what kind of mileage you're getting, and thereby using less or no gas at all. I don't feel that driving a Prius gives me permission to drive more & feel better about it; I'm also driving more conservatively now and going out as little as possible. I've been trying to change habits in a variety of aspects of my life to be more "green," and getting a hybrid was one goal of mine (it just happened sooner than I thought, thanks to the boyfriend totaling my Honda Civic!) -- not due to the gas prices at all...although, I'll certainly admit: it does help!
 
Well, I'm certainly not "brave" enough to try turning off my car when I'm driving it! Really, I'm just trying to be more conscientious about coasting, braking and starting off slowly. I think just that can make a difference.
 
When you guys talk about coasting...Is that in neutral or in gear? As most modern cars use no fuel while coasting in gear...Just a thought.....Or are you all automatic drivers as opposed to stick shift...As automatics use more fuel compared to the equivalent car in stick shift....

When I coast, my car is in drive...and no, I'm not opposed to driving manual; in fact, I prefer it. Almost all of my cars have been manual. However, in comparison shopping, I discovered the Prius to be the better hybrid (for myself, personally) and it only comes in automatic. And yes, I'm feeling quite indignant about that...:p

(I got great mileage with my manual cars, but I get better mileage now with my automatic-hybrid car...)
 
I have a manual, so I coast a lot anyway, and I use my gears more than the brakes , (if that makes sense). Putting your vehicle in neutral and coasting down hills, etc. is actually against the law in most states as that is considered not having control of your vehicle... Because my Jeep has such high torque, I usually start off in second gear when stuck in traffic, or when it's raining, but that's mainly to keep from spinning out, lol.... I have Nitro in the tires, but even so, I'm getting about 18 MPG...
 
Just want to clarify, do you mean while the car is on or off? Regardless of whether your coasting or not, if the car is started and on, it's using fuel. :)

Your wrong... Most modern cars have computers that know how much fuel is required, coasting requires no fuel so none is used... Well all cars except American it seems

No, as long as the engine is running it's using fuel to fire the pistons...

On a side note, the people that turn their engines off while waiting at the drive through... It takes more fuel to start the engine than it would to just idle...

No sorry your still wrong... Modern engines require no fuel to turn over while coasting... Honest

I saw on a documentary on hyperniling that modern fuel-injected cars don't really use that much fuel to start, so that if you're sitting for more than 10 seconds, you should go ahead and turn it off. I don't know the answer myself, this is just what I heard from a hypermiler on the documentary.
 
And coasting uses no fuel.... Come on these guys are scientists... they know down hill is free so they compensated when they programmed the on board computer....

Unfortunately you do not understand the simplicity of the Internal Combustion Engine. That's okay, I won't hate you for it. :D

In order for the engine to turn over, and run, fuel is ignited by the spark plugs. It's that simple. If the engine is running, it is using fuel. Doing a very very quick google search, here's a couple quotes for you from the same website:
http://www.fueleconomy.gov/FEG/atv.shtml
The rest of the energy is lost to engine and driveline inefficiencies and idling.
In urban driving, significant energy is lost to idling at stop lights or in traffic.
FYI, idling would be the same as coasting . . . ie. not applying pressure to the accelerator. Energy can't be lost if it's not being used (as you propose) can it?!
