If so why? And how can you find this information?
In: Physics
Yes, due to the gearing.
Lets take a RWD car as an example.
The crank of the engine is doing 3000rpm, which is connected to the input shaft of the gearbox, the drive goes through a series of gears/cogs and finally to the putput shaft, this turns the prop, which then turns the pinion in the rear axle, which will drive the ring gear on the diff, to which the halfshafts are connected, the wheels are bolted to the halfshafts.
So, if gears in either the gearbox or rear axle are changed the rate at which the wheels spin will change, therfore affecting speed. In fact, even the size of the wheel and tyre will change the gearing.
Here is a simple calculator: https://www.crawlpedia.com/rpm_gear_calculator.htm Note if you change either the rear end or transmission ratios the RPM changes.
Yes. Each car has gears that change the engine speed to the axle speed. But since the engines differ, the ideal engine speed differs. And since the wheel size differs, the same axle speed means different vehicle speeds.
