Plug-in hybrid electric vehicles (PHEVs) combine a traditional internal combustion engine with an electric motor and a rechargeable battery. This design allows them to operate on electricity for shorter trips, reducing fuel consumption and emissions. When the battery runs low, the vehicle can switch to gasoline or diesel power, providing flexibility for longer journeys. PHEVs can be charged using standard electrical outlets or dedicated charging stations, making them convenient for daily use. They typically offer a range of electric-only driving, which varies by model, and can help drivers save on fuel costs while contributing to a cleaner environment.
