Anyone here a hypermiler?

[gassy]

Some interesting info--sorry if this is a repost.

What did you find interesting about it? Seems pretty common sense to me.

Sure, but they have hats! And t-shirts!

If I was wanting to die of boredom, I would try it.

Some of the people doing this are suicidal. They are cutting their car off going down the highway and coasting, then starting the car and going again.

I have heard of some doing this in turbo diesels. I know it is not good to cut a turbo off when you are going 60 mph and letting it coast, (turbo gets no oil). On the vw diesels with the manual trans. when you let of the go pedal and the car is in gear the engine still runs but uses no fuel.

I have heard of them getting 800 to 900 mile on a tank of fuel, I only get about 630 before I chicken out.

Ummm, how can an engine run with no fuel?

[Porsche-O-Phile]

Just stay the hell out of the left lane.

When the car is in gear and moving the trans. continues to turn the engine at the same speed until it coasts down and the idle catches it. The tdi will idle along on flat ground in fifth gear, albeit slowly.

In Edmunds.com's tests, they slowed acceleration times down to a 20-second run from zero to sixty miles per hour. Compared to the kind of zero-to-sixty times we hear car makers bragging about these days, 20 seconds may sound impossibly slow. In fact, it is slow. But, while it won't get your pulse pounding, it will get you safely onto the highway.

So that's where all those clueless ass holes merging onto the freeway in front of me at 40 mph come from.

I guess activities like watching paint dry and watching flys f*ck have become passe.

We need new and improved ways to show just how bored we are.

Ha, I remember my dad went through a phase of turning off the ignition when coasting long downhill freeway sections. He is old-school Chinese, very thrifty. But one day when the freeway began curving he discovered he'd turned the key too far and activated the steering lock. I believe he stopped the practice after that.

That 5 other cars have to BRAKE for. So one car saves a quarter sip when 5 other cars loose a sip each.

I'm certainly not, but I'm considering buying a Silverado Hybrid when they come out at the end of the year so I've been checking out www.greenhybrid.com

There's a funny post where a guy tells the story of pulling up to a stop light next to another hybrid. They look at each and start rolling a little like they're going to race. When the light turned green they both took off... as slow as they could so they'd be all electric

They said the cars behind where honking cause they were going so slow.

I tend to put in the clutch or shift to neutral rolling down hills or approaching a stop.

In a car with variable valve timing, it makes a pretty big difference in fuel economy if you can keep the RPM's low.

In my Acura, if I drive like I like to drive, I get about 23 mpg around town, it is a hoot when you get on the big lobes of the cam, makes a great sound and will move it out pretty well. If I drive with an eye on fuel economy, I get about 30.

I do the opposite of hypermiling...
I sometimes borrow my parents Honda Insight if my car is in the shop, and it's fun to see just how LOW I can get the mileage. So far my record is about 44mpg.

Oh, man. That's FUNNY!

Hypermiling? There ought to be a law against it.

Made a quick trip to Roswell, NM yesterday for a family wedding reception. I decided to attempt to drive to optimize fuel economy but drive the speed limit (speedometer error corrected) and not impede traffic and not do things like shut off the engine, coast in neutral, etc. Drove a stock 2004 BMW 325i sedan with five-speed manual transmission. Tires inflated to maximum payload levels: 35 psi front and 41 psi rear. Average payload, passenger and cargo, was 270 lbs. Used the cruise control once up to speed limit, when traffic permitted only accelerated at the power level permitted by 30 mpg. I didn't immediately accelerate to the speed limit when leaving a reduced speed limit (town) if acceleration had to be done going up a grade; waited until saddle point of hill was crested. If there was traffic I immediately accelerated to speed limit (8-12 mpg). Used air conditioning for about 3/4 of the total driving time. Wind was blowing from the corners of the car most of the time out on the flats (Llano); I estimated I had an effective head/tail wind of 5 to 10 mph much of the trip. Outside air temperatures were 75 to 90 F much of the trip. There were significant grades leaving and returning to Los Alamos at 7000 ft. Typically had to stop at about six stop lights each pass through Santa Fe (45 and 35 mph speed limits). The majority of the trip was done at 70 mph or 65 mph with lesser distances at 55, 50, 45, 40, 35 and 25 mph. Google Maps estimated driving time one-way was about four hours and five minutes; I made the distance (225 corrected miles) in approximately three hours and 45 minutes (60 mph average speed). 12.505 US gallons of mid-range unleaded fuel ($3.959/US gallon) was consumed: car was refueled at the same station and with the same pump.

35.99 mpg was achieved.

Traffic was very light. Saw a Chaves County sheriff's deputy pull over a Cadillac Escalade with Texas plates that passed me doing an estimated 90 mph.

Jim,

That's pretty good! I have an '04 325i and I once got 34mpg in a combo of highway and mountain driving. I was surprised because of the mountains but I guess the uphills are conceled out by the downhills. I typically get around 25-26 in city/hwy mix and 30-31 on hwy only. I'm going to have to try your method next highway trip.

[David]

Our '99 323i got similar mileage on road trips. I never hear about other brands regularly beating their EPA mileage numbers. My truck sure as hell doesn't. The best I've seen in the '07 328i is 30 mpg, which matches the EPA highway mileage.

"The best I've seen in the '07 328i is 30 mpg, which matches the EPA highway mileage."

I've noticed this trend with dismay: BMW (and other manufacturers) have been introducing new technologies but have used the efficiency gains plus increased displacement to raise horsepower levels in what are already very competent sport sedans. Perhaps the vehicle weight has increased with the latest 300 series but I suspect it is just another "horsepower race". Perhaps now, given the greatly increased cost of fuel, the vector will swing around; it would appear that routine 35 mpg or better highway fuel economy is possible in a 180 hp 300 series sedan.
