The easy does it philosophy has been around for a long time. It used to be "Drive like you have a raw egg between your foot and the accelerator" now it's a simpler statement of "stay below 2500 rpm"..... but.....
I've always wondered if that is really better than a higher rev to get up to speed sooner. All the following numbers are completely arbitrary and have no connection to anyone's current version of reality.
Given a higher acceleration rate (25 mpg) for a shorter distance (1/4 mile)
.25miles divided by 25 mpg gives 0.01 gallons of gas used.
Given a lower accelation rate (45 mpg) for a longer distance (1 mile) to achieve the same final speed.
1 mile divided by 45 mpg gives .0222222 gallons consumed which seems to indicate that it takes around 2 times more gas to reach the same speed.
Someday I may have the time to test this out.
Or... has someone already done this?
