Plug-in hybrid is better. Plug-in hybrid is a new energy vehicle, which can drive the vehicle in pure electric mode and enjoy state subsidies when purchasing. Oil-electric hybrid is an ordinary motor vehicle. If you drive in pure electric mode, you can only drive for a few kilometers.
Plug-in hybrid is not complicated. In fact, it is equivalent to adding a large-capacity battery and a motor to the fuel truck, which can be driven by the motor on crowded roads and short-distance driving, thus avoiding the high fuel consumption of the fuel truck on crowded roads.
