powertrain
Engine to wheels
A powertrain is the system of components that generates power and delivers it to a vehicle's wheels.
In conventional vehicles, this includes the engine, transmission, driveshaft, and axles.
In electric vehicles, the powertrain comprises the motor, battery, and power electronics.
The new model features an all-electric powertrain.
