Info:Terrain Dependent Speed

From CoH-Stats

Vehicle Speed and Terrains

If you haven't noticed, vehicles sometimes move at different speeds, on the road they move faster, but in water they move slower.

These speeds are determined by Cover, which depends what ingame material it is driving on (ie. dirt, grass, road etc..). The default cover is defcover.
