Re: Down shifting to reduce stopping distance
I still don't understand... when you are not touching your accelerator and instead have your foot on the brakes, can the engine still drive the wheels or is there some sort of clutch (I know auto's don't have a clutch, but maybe something similar?) that disconnects the engine from the wheels?
Say you have your foot on the brakes, the engine RPM should be very low (around idle, or 1000rpm) but since you have your foot on the brakes the engine is "disconnected" and that 1000rpm is just idleing, not to drive the wheels. How then does changing the gears help slow you down?
Auto's give me a headache, can't figure out how they work!
