Study Reveals Plug-in Hybrids Emit Nearly Five Times More Pollution Than Expected

A new study reveals that Plug-in hybrid electric vehicles emit nearly five times more pollution than lab tests indicate, raising concerns over their true environmental impact.

• An analysis of 800,000 European cars found that Plug-in hybrid vehicles emit almost five times more carbon dioxide than reported in controlled laboratory conditions.
• The study reveals that Plug-in hybrid models, often marketed for their dual fuel capabilities, actually produce higher pollution levels than expected from gasoline and diesel engine standards.
• The findings challenge the perception that Plug-in hybrid vehicles are a cleaner alternative, as they were promoted by European carmakers to reduce overall emissions during long-distance travel.
