Plug-in Hybrid Vehicles (PHVs) are a type of hybrid car that combines a gasoline/diesel engine with an electric motor and rechargeable battery. They use much less gasoline than regular cars—around 30 to 60% less! The article explores how PHVs can improve fuel efficiency, reduce emissions, and perform better on the road. By looking at factors like vehicle weight, power, and size, researchers found that PHVs can be a great choice for environmentally friendly transportation. Sales of hybrid cars have been going up, showing increasing interest in these clean vehicles. PHVs recharge by plugging into electrical outlets, and they offer an effective way to cut down on fuel use and emissions while still delivering good performance.
