This paper talks about hybrid electric vehicles, which are cars that use both traditional fuels and electric power to run. The goal is to make vehicles more fuel-efficient and eco-friendly. Engineers have combined regular engines with electric motors in these vehicles to reduce pollution and make better use of fuel. They have made these hybrids perform as well as regular cars and even better in terms of fuel efficiency. Hybrid vehicles are seen as a solution to the limited charging points for fully electric vehicles. These cars are changing the car industry and are expected to have their own special support systems in the future. There are different types of hybrid vehicles based on the energy sources they use. The paper discusses these types and how hybrid vehicles can be used.
