Largest-ever-study confirms PHEVs burn up to five times more fuel than claimed
Fraunhofer’s analysis of nearly one million European plug-in hybrids shows a structural gap between laboratory certification and real-world fuel consumption, with actual on-road figures averaging five times higher than WLTP values /NMN
There is a systemic gap at the core of Europe’s plug-in hybrid policy, and it has now been measured at scale.
Using real-world fuel consumption data from approximately 980,000 plug-in hybrid passenger cars collected under the EU’s official on-board fuel consumption monitoring (OBFCM) system,
