Hybrid propulsion is a technology that combines two different power sources to drive a vehicle. Typically, this involves using an internal combustion engine alongside an electric motor. The electric motor can provide additional power and improve fuel efficiency, while the combustion engine can offer longer range and faster refueling options. This system is commonly found in vehicles like hybrid cars, which use both power sources to reduce emissions and enhance performance. By switching between or combining these sources, hybrid propulsion aims to optimize energy use and minimize environmental impact, making it a popular choice in modern transportation solutions.
