Plug-In Hybrid Vehicles

Hybrid vehicles are often considered the fig leaf of electric mobility. However, plug-in hybrids with a real electric range of about 60 km drive the same number of kilometers electrically as battery electric vehicles. Hence, their carbon dioxide reduction potential also is the same. This is the result of a comparison of solar power batteries and plug-in hybrid vehicles in Germany and the US by scientists of Karlsruhe Institute of Technology (KIT) and Fraunhofer ISI (Fraunhofer Institute for Systems and Innovation Research), which is now reported in Nature Scientific Reports.

Apart from approximately 50,000 purely electric cars, roughly 40,000 plug-in hybrid vehicles are presently being operated on German roads. These hybrids combine a conventional internal combustion engine with a battery. They are often regarded rather critically by environmental organizations and political decision-makers, as they are no "real" electric cars and are supposed to have a poorer environmental record. A systematic empirical comparison of the electric performances of battery vs. hybrid vehicles has been lacking so far.

This gap in research has now been closed by scientists of the Fraunhofer Institute for Systems and Innovation Research ISI and Karlsruhe Institute of Technology (KIT): They compared the performances of 49,000 battery electric cars and 73,000 plug-in hybrid vehicles in Germany and the US using data from fleet trials and automotive manufacturers as well as from websites for drivers to manage and monitor their vehicles.
