Mobility terms

How quickly a vehicle reaches speed from a standstill, which matters far more in practice than its top speed.

The speed a vehicle can actually hold on a given ground type, rather than the cap printed on its specification sheet.

How fast a vehicle actually turns on a given ground type, once engine power, weight and terrain resistance are accounted for.

The engine's output in horsepower, which only means something next to the weight it has to move.

How fast a vehicle turns on the spot, in degrees per second, which decides whether it can keep its front toward a faster opponent.

Engine horsepower divided by the vehicle's weight in tonnes, the single best predictor of acceleration.

Deliberately colliding with another vehicle, where damage scales with mass and closing speed and both sides take some.

How fast a vehicle can back up, which decides whether it can retreat into cover after firing.

How much each ground type slows a vehicle down, quoted for hard, medium and soft terrain, where lower is better.

The highest speed a vehicle is allowed to reach, which it only attains with enough engine power and forgiving ground.

How fast the turret rotates, in degrees per second, independent of the ground the vehicle is standing on.

The vehicle's mass in tonnes, which sets its power-to-weight ratio and decides who wins a collision.
