if you were in the desert and running out of gas, and the nearest gas station is further than your mileage will allow you to reach.

the idea is to put your pedal to the floor and go as fast as it will go(pulse), and then turn the key off(glide) until you come to a stop, and then repeat until you reach your destination.

my understanding is that if you get 10 mpg for 5 miles and you turn the key off you will coast for the next 5 or less and double your mileage. my question is will friction and wind resistance allow this idea to be of any benefit?

i say its good and i think it might work how about you

sounds good, but there is a lot of variables with gas mileage though.

I did this once. It was a special circumstance. I was in the mountains. I put the shifter in neutral & shut down the engine at the top of the mountain & coasted 25 miles to the first filling station I came to.

This technique is used by hypermilers and can result in a large increase in fuel economy if done correctly. The maximum speed for shutting down and coasting before repeating is about 70 kph to avoid wasting fuel because of increased aero drag experienced at higher speeds and is an awkward method of getting anywhere - not recommended for regular driving but certainly preferable to being stranded in the desert.

Slowing down to 60-70 kph will give you most of the effect without the aggravation if you find yourself caught with low fuel.

i have hypermiled myself, i had multiple modifacations on my jeep for better mileage. i had read about pulse and glide at ecomodders.com and is not practical in normal traffic, but i have always wanted to try it on a large scale in a place with enough room. pulse and glide is most beneficial when used with hybrid cars.
