In a motor vehicle, the powertrain consists of the source of propulsion (e.g. the engine or electric motor) and the drivetrain system which transfers this energy into forward movement of the vehicle.
The powertrain consists of the power source (e.g. the engine) and all of the components that convert the engine's power into movement of the vehicle (e.g. the transmission, driveshafts, differential and axles); whereas the drivetrain does not include the power source and consists of the transmission, driveshafts, differential and axles.
The most common types of internal combustion engines are:
Vehicles with both internal combustion engines and electric motors are called hybrid vehicles. If a hybrid vehicle includes a charging socket, it is considered to be a plug-in hybrid, while vehicles that do not include a charging socket (therefore relying on the engine or regenerative braking to charge the batteries) are considered to be mild hybrids.
