October contributed to the 2025 year-to-date BEV regional new passenger car penetration level coming to within 0.1 ppts of accounting for every fifth new car entering the Western European new car market (19.9%) so far this year. A combination of new products, lower-capacity batteries, and the debut of LFP battery chemistries from incumbents is driving OEMs to meet stricter regulatory CO2 fleet-average emissions levels from 2025 and the latest UK ZEV mandate, while new market entrants are boosting a hyper-competitive market. Total plug-in (xEV) market penetration grew to 29.9% so far this year. PHEVs remain on target to contribute at least 10% of total new car registrations for the first time, aided by Chinese models that mitigate against tariffs on Chinese-made BEVs.
