Definitions:

Rheostat

A two-terminal variable resistor incorporating a resistive track and slider, resulting in a single path for electrical current flow; the mechanical position of the slider will determine how much current flow is choked down by the resistor.

Powershift Transmission

A type of automatic transmission that allows seamless gear changes without interrupting power flow to the wheels.

Driveline Torque

The torque transmitted from the vehicle's engine through the drivetrain to the wheels, influencing acceleration and overall performance.

Slip Loss

The loss of power that occurs when there is a mismatch in speed between rotating surfaces, such as in clutches or drive belts.
