So, What Does it Do?The brief answer to what the O/D does is that it saves you money ~ above gas. When the O/D is on, your infection lowers the transformations per minute (RPMs) the the engine to make it work less to accomplish the exact same job.

The complete power of your?or horsepower?is the amount the your car is able to attain in a particular amount that time. Horsepower have the right to be calculation by multiplying your complete RPMs and also the speak of the vehicle. If your automobile is to run in overdrive, the RPMs will be lower, and therefore the car will have actually less power.
