- Real-world CO₂ emissions of PHEVs are five times higher than official figures, averaging 135 gCO₂/km.
- The utility factor (UF) overestimates electric driving share (84% assumed vs. 27% real-world), leading to underestimated emissions.
- PHEVs emit 68g CO₂/km even in electric mode due to combustion engine use, costing drivers an extra €500 annually in fuel.
- Long-range PHEVs (>75 km) show higher emissions and larger gaps between real-world and official values due to design flaws.
- EREVs, despite technical advantages, share PHEV drawbacks with high combustion mode use and uncertain benefits in Europe.
- Weakening EU car CO₂ rules could increase emissions by 64%, adding 2.8 GtCO₂e by 2050, derailing climate goals.
- Carmakers avoided €5 billion in fines (2021-2023) due to WLTP underestimation, with VW, Mercedes, and BMW benefiting most.
- Well-designed PHEVs need e-motor power 3x combustion engine, 200+ km range, fast charging, and limited fuel tanks (15L) to reduce emissions.
- EU must maintain 2030-2035 CO₂ targets, safeguard UF corrections, and prioritize BEVs to avoid hybrid dependency and meet climate goals.
