The first data collected by the EU shows that plug-in hybrid cars are much more polluting in reality than in lab tests.

Data collected by the European Commission shows that plug-in hybrid cars are not fulfilling their efficiency potential because they are not plugged in and used in 100% electric mode too often. The study raises questions about the real efficiency of plug-in hybrids, questioning the environmental benefits compared to cars with internal combustion engines. Manufacturers are accused of presenting plug-in hybrid models as environmentally friendly, but in reality they are much more polluting than previously thought.
