The distinction between whether a vehicle is electric or a plug-in hybrid has 
nothing to do with how much more or less pure electric range it has than other 
vehicles of the same configuration.  The Volt, just as any of the other plug-in 
hybrids, has two fuel/energy sources: an electrical outlet and a gas pump.

The name differentiation is *bad* as it confuses buyers into thinking that the 
Volt is something other than a plug-in hybrid when many people are already 
confused between the difference between a hybrid and an electric car.  The only 
purpose it serves is to allow Chevy to pretend that the Volt is in a class of 
its own.

The 2017 Prius Prime offers 25mi all-electric range vs the first generation 
Volt's 35mi, yet one is described as a plug-in hybrid while the other is an 
"extended range electric vehicle"?  Many of us have (or have had) pure electric 
conversions with less than 25mi range, but they were (are!) still 
unquestionably EVs; is it helpful to anyone to invent a new vehicle class to 
differentiate shorter-range EVs from all other EVs?  I certainly don't think

Big difference between a Volt and an electric car, indeed!  My sister was quite 
disappointed to find that her first generation Volt would *not* allow her to 
make her short commute on battery power alone in winter, despite the car being 
garaged each night.  Very unlike an EV, this vehicle insists upon running the 
ICE for much or all of her commute in cold weather despite the battery being 
fully charged and having more than enough range the trip in pure electric mode. 

IT is NOT an electric vehicle with an on-board range-extender (that one can 
choose to use or not), which is what one might reasonably expect based on the 
'extended range electric vehicle' classification; it is a plug-in hybrid that 
happens to have the greatest all-electric range of the present offerings.

I like the Volt, but don't see its greater range justifying invention of a new 
vehicle classification (with it as the sole member) any more than it would make 
sense to invent new vehicle classes for the EV with the longest range or the 
ICE vehicle with the longest range to allow their manufacturers to pretend that 
their vehicle is in a different class from all others.
