PHV means "Plug-In Hybrid Vehicle". It's the universal standard established to identify all plug-in hybrids. It will become quite useful over time, as other automakers offer their own models. That's a much better way to distinguish the difference between the plug-in and the regular model than an abbreviation unique to each hybrid. In other words, I haven't been and have no intentions to support PIP. Past experience has made it overwhelming clear that newbies have no idea what the heck you are referring too, since the same convention was used to differentiate traditional models from hybrids and it was quite ineffective. Keep your audience in mind. PIP means "Picture In Picture" for anyone familiar with television. PIP also already refers to the measurement of fuel on the Prius gas gauge. PHV is distinct, yet can be used across the industry. Any hybrid that offers a plug as a package-option needs some type of simple identifier. PHV will work well for that.
