Car dynamics
Datamined from ROLLER.
Game engine runs at 36 Hz (before any speed up cheats).
ENGINES.C defines max speed constants for each gear for each car. CAR.C converts these into units used by the handling engine (CONTROL.C) and track files by multiplying them by 2.2 (let's call these "Whips").
FUNC2.C converts Whips into mph and km/h which are displayed in the UI.
-
mph
$= Whips / 3$ -
km/h
$= Whips \times 0.625$
Note: 1 mph = 1.875 km/h in the Whiplashverse.

ENGINES.C contains each car's
Deceleration per tick (1/36s):
-
Coasting in gear:
$\frac{V_{max}}{Drag \times 256}$ -
Coasting in neutral:
$\frac{V_{max}}{Drag \times 256} \times 6$ -
Coasting off-road (in gear or neutral):
$\frac{V_{max}}{Drag \times 256} \times 16$ -
Braking:
$\frac{V_{max}}{Drag \times 36}$ -
Braking off-road:
$\frac{V_{max}}{Drag \times 36} \times 3$
