in NASCAR, what is the "differential" gauge reading/measuring?
in nascar at the bottom of your screen, we can tell how fast is a car going because they provide us with live data,, data such like speed, Throttle position, brake pedal and something related to differential, my question is what they really mean in this option,, what are they measuring? thank you
RPM's which is the revolutions per minute the engine is turning. IF that's not it, I really don't know what you are talking about exactly. If you are talking about the time that the leader has back to the other cars behind him then that is a measure of time in seconds. This measurement shows how far behind each car is to the leader of the race. If a car goes a lap down then it will say -1. If a car is behind the leader 10 seconds, it will have the driver or car number and -10.00
