A powertrain system is a crucial component of a vehicle that includes all the parts that generate power and deliver it to the wheels. This system typically consists of the engine, transmission, drivetrain, and differential. Together, these components work to convert fuel or electrical energy into motion, allowing the vehicle to move. Powertrain systems can vary significantly between different types of vehicles, such as internal combustion engine vehicles and electric vehicles. In electric vehicles, the powertrain includes an electric motor and a battery, while traditional vehicles rely on a combustion engine. Understanding these systems is essential for vehicle performance and efficiency.
