The first thing to know about the 2018 Honda Clarity PHEV is that PHEV stands for plug-in hybrid electric vehicle. The second is that the plug-in part is not mandatory: As the word "hybrid" suggests, there’s still a gasoline engine in addition to the electric motor, so no one will be stuck by the side of the road if they run low on battery power.
This is the third mid-size sedan to bear the Clarity name. The initial version was powered by hydrogen fuel cells, and it was followed by a solely electric vehicle. The whole Clarity project is Honda’s green-car initiative aimed at bringing low-emissions technology more into the mainstream. This plug-in hybrid model promises to be the most popular yet.
