Let's start with the basics.
The internal combustion engine needs three ingredients for it to run properly.
Fuel, air and Spark. The fuel mixes with the air in the combustion chamber and a spark is introduced via the spark plugs which causes the engine to run. RPM, which stands for revloutions per minute counts how many times the number 1 Cylinder fires. Every car has a specific firing order which causes the engine to run. for example a Chevy 350 and Oldsmobile 425 Cubic inch V8 have the firing order 1,8,4,3,6,5,7,2. When you press on the accelerator you (the driver) are giving the engine more fuel so the engine has to run faster to burn this extra fuel. thus the faster the engine runs, the higher the Revloutions per minute RPM.
Pressing on the accelerator increases engine rpm (revolutions per minute) which in turn increases wheel/tire rpm which increases vehicle speed.
Tranny problem.
With the car on, press the accelerator pedal.
Low fluid or low pressure for another reason which increases with rpm.
If its manual that would be the cltuch slipping.
It is normal for the RPM to increase a little when put in park or neutral. If the RPM increases by a lot, then you need to adjust your idle speed.
I think that happens when you are changing gears. If you make the engine goes to 3000 rpm and suddenly release the gas pedal and rapidly press down the clutch pedal. The rev would up. With very noisy sound. Isn't it?

The RPM normally increases as you push the race pedal in your VW. However, it is possible that the wire for RPM might be broken, causing it to suddenly increase without race.
The engine RPM (Revolutions per Minute) increases.
