Today, the popularity of plug-in hybrid cars as well as actual sales have been slowly developing improved, many consumers have become owners of new energy vehicles. It relates to a plug-in hybrid system, I believe that many consumers or owners so far are relatively vacant. Today we are going to talk about the topic will also be associated with a plug-in hybrid system: long-distance running in the state unplugged, the fuel economy of plug-in hybrid will be better than ordinary fuel car?
by weight Infrastructure
Previously, we need to plug-in hybrid system is the basic structure of an analysis . We know that the plug-in hybrid is in fact on the basis of the original fuel vehicles, by increasing the electric motor, battery pack and electric control system to make up, and to make these components by electronic control system can collaborate, or work alone. This is to some extent also confirmed, plug-in hybrid system will have a weight disadvantage, and for the coordination of electric control system has a very big test. 
long-distance fuel-efficient driving it?
For most of the plug-in hybrid, if compared with the pure fuel vehicles cars of their own, in a state where long distances unplugged, then the ordinary fuel vehicle fuel the economy is bound to be better. There will be two main reasons: one is the weight, the other is to match the sophistication of electronic control systems. Of course, there will be exceptions, such as the Corolla dual engine + E plug-in hybrid on the system, in the unplugged state is still able to have a very good fuel economy performance. 
Summary: The above is about a number of issues plug-in hybrid system solutions.
