From a stop should car be gunned up to speed?
 

O.K. the question is, from a stop, should one quickly accelerate up to a optimum operating speed where there will be the best mpg. Or should one accelerate , gradurally, which will take longer to get there & perhaps burn more gas than a faser accelaration over a shorter time. This is a physics/math question. Voulme = E MC 2, etc. Consider, if one wanted to stay the dryest and was in a stright down rain pour and wanted to go 300 feet to shelter. Should one walk or should one run for it, to stay the dryest? You see if you walk, you are being hit with the regular stright down drops for a longer time (like a slow acceleration). But, if one ran they would get the normal, stright down pour for a shorter length of time but, would also be running into rain that would have otherwise fell to the ground, had they not run into it. Seems like they are getting a double dose of rain but, for a shorter time. Would both ways get the same wetness? We will not consider if a wind was involved? I say they would get wetter to run. (Also, I think a fast acceleration will, over all, use more gas?). (plus the runner will run into rain down their whole front body & get very wet. A walker would mostly get the rain on ther head/shoulders (such would be wetter but the lower body would be dryer than if it ran into rain.) So we can mix MPG, Rain & physics/Einstien together and save money and gas.

Here is my take on it: https://crxmpg.com/accelmpg.html

Certainly doesn't apply to every car in every situation though.

Yeah. ~3/4 pedal and make sure the car shifts early. When I leaned out my WOT fuel injection is saw what's imo a noticable increase in efficiency, since stock was ~12:1 compared to the ideal of 14.7:1. According to somthing SVOboy linked earlier, that means I could've stood to pick up as much as a 20-30% gain in efficiency during WOT.

You're supposed to accelerate along the torque curve for your vechile. Where you would find a chart of the torque curve I have no idea though.

This will depend on if it's a standard or auto on how to accelerate. This has been covered before do a search and I'm sure you'll find it.

Well everyone has just about covered it

...except you could use an umbrella. ;)

dont laugh at me please what it wot? its been a while since ive seen that used and i forgot what it was

Wot= Wide Open Throttle

lol thats why i didnt know it becuse i never do it. thanks for pointing out the obvious

WOT = wide open throttle.
on most fuel injected cars I've looked at, when the fuel presure regulator feels the drop in vaccum in the intake manifold, it bumps up the fuel presure so it can dump that extrea fuel in to produce more power, so if you use a light foot on the pedal it's going to keep the fuel mix leaner.
so really it seems like if you feel the need to accelerate faster then accelerat just below that point that you can hear the exaust/engine change in sound.
to go back to the idea of accelerating slowly, think of ridding a bicycle, does it use more of your energy to try to get up to full speed all at once, or slowly? I say being more aware, and shifting at what might feel like being slightly early might be the way to go.
