I just don't see the point in this car for most folks. If you live in a warm climate, get an HOV sticker, or can get the car for less than the price of regular hybrid with tax credits, then the car makes some sense.
The think the 6 speed transmission makes the car over complicated for a PHEV, the lack of an electric heater makes the car a warm climate vehicle, and the battery is a bit too small.
Frankly, I think you buy a PHEV so you can drive the car the majority of the time as an electric vehicle and have a gas engine backup for longer trips. Without an electric heater, this car doesn't do that unless you live in a warm climate.
Go to the Honda Clarity forum and you will see how a PHEV should be designed.
