How is vehicle speed calculated?

[EvgenijM86]

And a couple more questions:

1. Does propulsion gives speed equal to max_speed * x%, where x% is different for each propulsion (link)?
2. Does weight affect speed like this - prop_speed (weight / engine) ?

An example here - http://guide.wz2100.net/u/heavycannon-python-tracks
Total weight is 30250. Engine -20000. Speed is 52.

My calculation is:
Tracked propulsion gives 125 * 80% = 100 speed.
Vehicle speed is 100 * (20000 / 30250) = 66.7 speed.
What do I need to change to make it 52?

125 is the max speed of tracks. It's not used except as a speed cap.

The formula is pretty simple.

engine * propMult / weight (capped at maxSpeed)

20000 * 80 / 30250 = 52.

For actual speed, you also have to multiply by the terrain multiplier, and the experience multiplier, which I haven't gotten around to doing. :/

Thank you.

um for the sake of calculation what is the weight % for propulsion for?

[Zarel]

weight is calculated as

bodyWeight + bodyWeight * propWeightPercentage + turretWeight
