Plug-in hybrid
It is obvious for most people that internal combustion engine cars cannot represent the future anymore because of the oil reserves that are estimated to be finished in forty or fifty years. Obviously, Plug-in vehicles cannot be considered a short term option because we lack the needed infrastructure and capable batteries for increasing the autonomy that is currently limited. The general opinion was that, at least for the next seven or eight years, Plug-ins are not going to become the standard in hybrid vehicles and that regular HEVs will have the biggest proportion on the market.
