 We are used to distinguish different types on energy-propelled vehicles:

 les   •  « monocarburation vehicle » :they use a single source of energy ( GO / LPG / CNG / LNG)                     les
 •   « Bi-carburetion vehicles » : they use 2 different types of energy (GAS/NGV or GAS/LPG for example)
 sur      •      «Hybrid vehicles»: they go at least 2 different energy transformers and at least 2 different disposals to keep the energy into batteries.   sur
 Hybrid vehicles we often encounter are Electric Hybrid Vehicles (EHV).

 the battery is separated from his casing.
