Calculation of speed, UPDATE available!!! Hello together,What speed does my car drive at a certain speed? This question has been asked here in the forum many times recently. That’s why I wrote a small Excel program, which gives you the speed depending on the speed, the translation and the tyres – and that in any gear. You can download the programs from me on the homepage. You need the program “Mature calculator.exe” to determine the rolling range of the respective tyres. And the program “Vmax-Berechnung.xls” calculates the respective speeds in the individual gears. You only have to give the following information: – tire rolling range (from tire calculator.exe) – engine speed – gear ratio – gear ratio of the axle Then the program spits out how fast you really drive at the respective speed. so, have fun now! ciao
