Question:
What will be the benefit ?
In what condition should I turn on the overdrive ?
Answers:
In modern transmissions the highest gear manual or drive on automatic transmission
is now overdrive allowing for lower engine rpm at cruise where torque is no longer the most important factor, this results in improved fuel economy.
By contrast the lowest gear on mountain bicycles is 1 to 1 (direct drive) and all higher gears are over drive. This is due to the high power of the power plant (our weight and gravity) compared to power needed to move the load forward on a bicycle.

It would be the next gear after your highest and it is for saving gas and making less work for your engine while traveling at a high speed.What is the best style for a BMW 335i sedan?
over drive is a higher gear, use it on interstate highwaysOverdrive is a ratio of input shaft to the output shaft. In a transmission the final ratio is 1:1. With an overdrive transmission the ratio is more like .87:1 . In other words, the input shaft will only turn about 7/8ths of a revolution while the output shaft turns one complete turn. This helps save gas and improves fuel economy. Due to the torque curve of the engine, the overdrive gear can only be used at higher speeds, say above 45 or 50 mph.

Overdrive should always be on to save gas. The only time you should press the overdrive button to turn off overdrive is when you are going up a steep hill or when you need more power (when it is turned off, there will be a light that says "Overdrive OFF").More Questions & Answers ...
