The Green Cars Cometh

摘要

A hybrid has a combination of two power sources: an electric motor, and a petrol or diesel engine. This is an extremely useful feature when it comes to long stints of city driving, where only the electric motors are used. The key to a hybrid car is that the petrol/diesel engine can be much smaller than the one in a conventional car. The advantages of a series hybrid car are huge. They are less complex because only the electric motor, with its huge range of usable RPM, is connected to the drivetrain.
