Hyper Mileing

[Da Klugs]

Stayed late last night. Roads were empty at 1 am so tried to stretch it a bit. Forgot I was in Neutral once though and rev'd it to 4500 RPM.. arrgh.

21.8 for the trip home. 40 MPH max speed. Max speed limit was 35. Rolled the 3 stops but got caught at the light for 20 seconds.

It's amazing when I go in early/stay late what a difference it makes. I can pick up 2,3 sometime 4 mpg just by getting outta traffic. When you drive a 10,000lb beast, inertia IS NOT your friend, at least not if you have to stop. I'll have to try a few of the other tactics though.

(btw, I have a 20 mile commute each way)

Tonight decided to try and "hypermile" and see how much better mileage the trip computer would yield. Kept it below 1800 RPM (car wont upshift even with the paddles below this RPM) when I was paying attention. Got up to the speed limits and cruised.

Got delayed exiting the lot and had to do a full stop.
Made the right OK.
Made the right on to the N/S without having to full stop.
Made the first light, missed the second had to stop.
Made the third light.
Made the left without having to stop.
Neighborhood cruise was smooth.

18.8

Pretty amazing the difference between "normal" and if not hyper at least paying attention mileing. Gonna make it a daily commute game.

I think the only way I could hypermile would be to walk.
Out of my 4 vehicles, the best one gets 14.8 mpg.

The worst I've gotten was 29 on the highway with sub-freezing temps at 75 mph. The best I've gotten is a bit over 40 around the city. Usually get between 32 and 36 combined. I have an Altima Hybrid. What I like about the car is I can basically drive it normally and get at least 32 MPG. It's only got 200HP, but it moves better than my last car which was 205HP. It's plenty fast for not being a sports car and downright crazy fast for a hybrid. (fast for a hybrid isn't saying too much)

I've never tried hyper mileing but I've noticed that people tailgate me a lot more in the hybrid because they assume I'll drive like a wuss in it. Even if I'm going my normal 5 over, I still get tailgated a lot more.

Land Rover was made for discovering, and gas guzzling, not for fuel efficiency. I think I get right about 12 around town, increases to a sweet 18 on the highway doing 70. When I go off road and downshift I get a solid 8. I could prob. sell this get something cheaper and use the money I save on cigars...Now that is a plan!

I am thrilled gas is going down. I have never tried this "hyper mileing" you guys speak of, but I will now!

Kinda forgot until the first stop sign (3/4 mile) that I was going to do this.
Was at 9.2 at that point.

Rolled the stop sign out of the neighborhood.
Rolled the right stop onto the N/S.
Made the light
Took the left at 35.
Made the light and took the right @ 30
Made the left @ 30
Rolled the stop sign and made a left
Right @ 20 into lot and Unfettered to my parking spot

17.4

Things I'm doing differently:

1800 rpm max (except for the beginning today)
Shifting to neutral here and there.
Forcing upshifts on the paddles
Trying to keep momentum... avoiding full stops.

Wow, Dave, I've never even heard of hypermileing. I may just have to try it to see. I get a pretty solid 17 - 18 mpg on my 55 mile roundtrip commute every day. Pretty cool; thanks for the idea!

Just one question? Do you save enough on gas to make up for traffic tickets for rolling the stops?

My thoughts exactly when posting the line. I think that changing the definition of a stop sign to "sub 2mph" vs a full stop would save millions of gallons of gas every year. That initial point of inertia has gotta be ugly from an energy use standpoint. Changing it is something that we could do though that does not carry a direct cost.

..........so.........after you factor in the costs of your traffic tickets when you get pulled over for rolling stops, what's the bottom cost-benefit analysis look like???


EDIT: Forget the dummy. MY post shows the need to read the whole thread

Hey we are trying to save the planet here!

[shilala]

I get 15mpg in the Envoy while I'm smoking a cigar, lounging in my giant heated seats, listening to my ipod at mind-numbing volume.
I don't even have to pay attention or nothing, still 15.5 mpg.
I can't imagine giving up all that comfort and power to get 12.8 mpg on the way to the bank. That'd make me crack.

What's that thing gotten over the life of the car?
Since I got my Envoy it's 15.5 mpg. I've wondered how the Prius really does cause I hear a lot of folks griping.

Only in my use of pithy comebacks.

Audi A8L, 350 hp V8, is pretty comfey as well.

Atta boy.
I can't imagine stuffing my fat ass in a Prius.
I'd need some grease and a big shoehorn. I had to drive those little cars when I was a kid. I don't think I'd be able to bring myself to doing it all over again.

The thread title is misleading. Just my lil way of amusing myself with experimenting with how my driving style impacts mileage. It's been interesting how little changes (limiting RPM not speed) can have big impacts on city MPG. Big changes can have additional impact... rolling stops, using neutral etc.

I was confused so I went back and read some more and I get it now.

Be aware that coasting in neutral with most modern automatic transmission cars will actually hurt your mileage. (I don't know if this is true with maunal transmissions too) A modern automatic -- when you are coasting with your foot off the gas, will drop into a mode where it only fires cylinders frequently enough to keep the engine spinning, but while in neutral, it actually uses more gas because it's at a full idle. You can see it on some car's computers -- my wife's Subaru Legacy shows the mpg meter max out at 99.9 mpg (which means it's probably higher) while coasting in gear as opposed to about 65mpg on the same hill/speed while in neutral.

Noticed my Maxima seems to get better mileage in gear also. (tough to tell for real -- no computer display).

I just do it to save more gas money for my '03 SVT Cobra -- has a supercharged V8 that I've gotten down to 2mpg whilst "driving spiritedly". (it normally gets about 18-20mpg around town, though)

Oddly enough, while at work I was goofing with my tune and sorted my launch control out.

Not my car but basiclly what it sounds like.
Taking odds I get pulled over on the way home...
