Full hybrid and plug-in hybrid vehicles are relatively similar in that they usually have a substantial battery pack, and that they have the capability to be driven purely on electric power if there is sufficient charge in the battery. Where they differ is that full hybrids only charge their battery by regeneration during braking or by using the engine as a generator.

Plug-in hybrids can perform these same actions, but have the additional option of being plugged in to charge the battery. If you have the facility to charge by plugging in this gives the opportunity to travel an increased mileage solely on electric power. If you are not ready to commit to a pure electric vehicle and have the facility to charge, a plug-in hybrid can mean reduced running costs and emissions. Which one suits you best is a matter of personal circumstances, particularly in respect of how easy it is for you to plug in and charge. If this is problematic then a full hybrid is likely a better option, but if you can plug in easily then a plug-in hybrid offers additional benefits.
