I have a manual transmission and was under the impression that a certain RPM on a particular gear will always generate the same MPH. The other day I noticed I sit at 2,800 RPM in 6th gear @ 80 MPH, and other times it’ll be at 3,200 RPM – Could some explain?
In: Engineering
Road conditions, the mood of the engine, and the load in the car can affect the RPM. It can also be affected by hills or the wind because you are putting more/ less pressure on the engine to produce power due to the load.
