Antriebe: Klimabilanz von Plug-in-Hybriden wird immer schlechter
Dass Plug-in-Hybride nicht so klimafreundlich sind wie behauptet, ist bekannt. Der Abstand zwischen Prüfstandwert und realem CO₂‑Ausstoß wird allerdings immer größer, zeigt eine neue Studie.
Berlin - According to a recent analysis of new EU data by environmental group Transport & Environment (T&E), the gap between official and real CO2 emissions of plug-in hybrids is widening. For the 2024 models, the real emissions averaged 145 grams of CO2 per kilometer, compared to only 24 grams in the official WLTP testing. This marks the first time that the real-world emissions surpassed the official figures for plug-in hybrids allowed for sale.
Just one year prior, the discrepancy was 138 grams in practice versus 28 grams in the test. The official figures for climate gas emissions decreased by about 15% from 2023 to 2024, while the actual emissions increased by 5%. As a result, the difference between the two values grew from 110 to 121 grams per kilometer within a single year.
The divergence has been steadily widening over the long term as well. In 2021, plug-in hybrids still had real emissions six times higher than the official value, according to earlier T&E assessments. In 2022, the factor was eight, and in 2023, it was just under nine. For the 2024 models, the factor is now around six. This trend has continued uninterrupted since the EU's practical testing measurements began in 2021.
