In drive, the ratio of the transmission gears is 1:1. That means that the input shaft turns one revolution and the output shaft turns 1 revolution.
In overdrive, the ratio is changed to something like 0.83:1.
That means the input shat from the engine will turn less than one revolution while the output shaft will make one full turn.
So the rear wheels will turn more times and you will use less gas and get better gas mileage, but you have to give up some acceleration to get it. So when you step on the gas, the transmission will downshift back to the 1:1 to help you get to the higher speed faster and then it will go back to the overdrive ratio. Good luck

Overdrive is like another gear. If you drive an automatic, drive has three gears, overdrive is like a fourth. Basically, use overdrive on the highway to ease the engine's RPM, which saves gas. Turning off overdrive gives you more power for accelerating and for uphill driving.

regrettably, maximum persons do no longer comprehend that, functionally, there is not any distinction. the person-pleasant time period, emotion, oftentimes is considered as some thing different from the technical time period, influence. Even professionals, which incorporates Ekman and Tompkins have made unnecessary differences, complicating the image. Emotion, or influence, is a persons lively (non-verbal) reaction ( or "reading") of the interplay with their ecosystem. Emotion provides us coaching about, and the flexibility to finish actual initiatives, suited to the situations (which incorporates survival). because it really is non-verbal, it really is considered to be less than the breaking point of wakeful knowledge, hence the note "subconscious" used for this adventure/feeling. Tompkins did have one project brilliant: influence is known. because it develops before wakeful, verbal-depending cognition, it has a significantly better impression over habit than wondering. maximum politicians and promoting pros can attest to this. notwithstanding, this lively enter isn't a command, it really is in basic terms an impression. because body impacts recommendations and strategies impacts body, we may be able to rekindle thoughts that ought to bear in mind emotional responses. The foundation is from environmental interactions, no longer from wondering. yet we may be able to call up certain emotions with out interplay contained in the instantaneous. We in basic terms draw on adventure. even notwithstanding oversimplified, W.B. Cannon replaced into precise.

you put your car in overdrive when you are going about 45-55mph or faster and want to save gas. it depends on the model as to when you want to put it in overdrive. if you are climbing a hill, you take it out of over drive so you will have more power.

Overdrive is used for highway speeds. It allows the engine to turn slower. This reduces strain on the engine and gives better fuel economy.
