Thanks Tom but that's not what im looking for. The EPA rates vehicles based on the emissions they expel so some are rated as LEV some ULEV some PZEV etc. So that means a full electric vehicle would be rated a ZEV as zero emissions vehicle, where does our gas electric fall as it does have a combustion engine and does emit carbon.
All-electric (also known as battery electric vehicles (BEV).
Chevy Volt and Cadillac ELR are EREVS
Note: The Chevrolet Volt and Cadillac ELR were a challenge as they cross categories and an argument could be made for them being slotted into the “electric” category (albeit with generator backup) or “plug-in hybrids.”
Given they have dual power trains, by a strict definition, they are plug-in hybrids, but their powertrain architecture operates not quite like the rest of the PHEVs.
General Motors calls them “EREVS for “extended-range electric vehicles” and this is not just marketing hype.
For example, a firm press of the accelerator will not kick the Volt or ELR’s gas engine on as it would with a Toyota or Ford PHEV.
GM’s EREV vehicles operate like EVs as long as they have battery charge and are very nearly pure series hybrids. Much of the time they do operate like series hybrids, but there are exceptions.
Their gas engines only rarely are used to mechanically power the front wheels, and for the most part are used solely as a generator for the electric traction motor.
In contrast, a Prius PHEV or Ford Energi revert to parallel hybrid mode if the battery is exhausted.
