Which statement best describes a plug-in hybrid's charging capability and electric range?

• A. It cannot be charged from an external power source
• B. It cannot run on electric power
• C. It uses hydrogen fuel cells
• D. It can be charged from an external power source and can run on electric power alone

Answer: (D)

Plug-in hybrids have a rechargeable battery that can be charged from an external power source, and they can drive on electric power alone for a portion of the trip. You can plug in at home or at a charging station to recharge the battery, then use electric mode for short trips without engaging the gasoline engine. When the battery charge runs low, the internal combustion engine or a generator takes over to continue driving. That combination—external charging plus electric-only driving range—is what sets plug-in hybrids apart from conventional hybrids and from hydrogen fuel cell vehicles.
