NEW Hypermiling thread
I know, going for fuel economy in an expensive, high-maintenance, 4500 lb truck seems a bit counterintuitive, but I see it like a sort of game

As long as you know your car burns more fuel if you put it in neutral while coasting down hills than if you just take your foot off the gas.

I'm in for curiosity sake. In the past, I've used elevated tire pressure and weight savings with a "stingy" driving style for some impressive results...

Or you can just go the diesel and get similar fuel economy to our previous petrol 4cyl sedan without even trying!

Unfortunately, we'd have to try REALLY hard to do that in an E53 up here.

Don't feel bad, people here make it hard to hypermile. Sometimes it seems like almost everyone here likes to race to red lights, stop at the green for no apparent reason, tailgate, change lanes without signalling, and brake hard going downhill instead of coasting... yet I am undaunted!

Also, a car going up hill in say 5th gear @ 2000 rpms @ 75% throttle. Same car going up the same hill, same speed, in 3rd gear @ 4000 rpms @ 25% throttle. Which one is getting better fuel mileage? My thoughts are if the car is FI, it would be the 5th gear and opposite for a carbureted car. Any thoughts? |

Best practices... Use the hills to your advantage. speed up on way down and slow down on way up. Acceleration... Burns more fuel than anything other than a cold start up. Slow, easy, allowing the trans to get in to higher gear will give you all there is to gain. coasting.... In gear or out of gear? Out of gear allows you to speed up with out engine involvement. You are left only with rolling and air resistance. The fuel is cut off when coasting in gear but the drivetrain will slow you down REAL QUICK. Now the real questions should be "What is the wear on an auto trans when coasting in neutral, if any?" For those of us who do not give a rats ass other than to say "hey, it is double digits!" I say hard acceleration is why we own the V8's with fat tires. If you want fuel economy sell it and buy a 4 cyl whatever, with skinny tires and a manual trans. I personally use my Vespa to run to the post office and the bank. Early mornings only on weekend as I do not care to become a bumper ornament on a texting idiot's Honda.

Well said. Not into gas mileage, but curious. I love mashing the pedal and being sucked back into the seat as you blow by the guy in a raced out Honda who has all ready passed you three times! (That should of went in the "Ya Baby" thread) At the moment I believe I'm right at 13.1 mpg and that's mostly city. |
