The Reality Behind Plug-In Hybrid Fuel Efficiency Revealed
Recent findings suggest that the fuel efficiency of plug-in hybrid electric vehicles (PHEVs) is significantly overstated by manufacturers. A comprehensive study by the Fraunhofer Institute, analyzing data from approximately one million PHEVs produced between 2021 and 2023, has shed light on this discrepancy.
The study extracted real-world fuel consumption data directly from vehicles across various manufacturers, revealing a stark contrast to the figures presented in their official EU certifications. PHEVs, which are designed to alternate between a conventional combustion engine and a battery-powered electric motor, are promoted as energy-efficient alternatives to traditional cars. However, the study found that these vehicles consume an average of six liters of fuel per 100 kilometers, contrary to the one to two liters per 100 kilometers often claimed.
The primary reason for this higher consumption is the frequent switching between electric and combustion modes, contrary to manufacturers’ claims that PHEVs utilize minimal fuel in electric mode. Patrick Plötz from the Fraunhofer Institute noted that the combustion engine in these hybrids activates more frequently than anticipated.
Among the vehicles analyzed, German-manufactured PHEVs, particularly high-end models like Porsche, exhibited the highest fuel consumption. Porsche hybrids were found to consume around seven liters per 100 kilometers, especially when the electric motor was engaged. In contrast, lower-end models from Kia, Toyota, Ford, and Renault demonstrated significantly better fuel efficiency, often using under one liter per 100 kilometers.
In response to inquiries, Porsche attributed these differences to “differing usage patterns” and maintained that their fuel consumption figures align with legal EU measurement procedures. They emphasized that variations in real-world consumption could result from factors such as road conditions and driver behavior.
These findings have prompted scientists to call for adjustments in EU regulatory measurements to better reflect real-world emissions. There are suggestions for imposing penalties on manufacturers whose vehicles exceed emission limits in practical settings. However, the EU Commission has yet to comment on these revelations, while the German Association of the Automotive Industry remains confident in current measurement methods.
