Battery electric vehicle registrations across Europe increased by 41% year-over-year in May, according to an analysis by Jefferies covering European automotive markets. That rise pushed BEV penetration to 23.6% for the month, a gain of 6.2 percentage points compared with the same month a year earlier.
Jefferies attributes part of the outperformance to incentive programs active in several major markets, specifically naming Germany, Italy and France as supporting factors for consumer uptake. Within the competitive landscape, Volkswagen ceded BEV market share while Leapmotor, Tesla and multiple Chinese automakers made gains over the period.
Jefferies' sample of seven principal European economies also showed continued growth in plug-in hybrid electric vehicles. PHEV registrations rose 17% year-over-year in the sample, lifting plug-in hybrid penetration to 11.2%, a 1.3 percentage-point increase versus the prior year.
At the brand level, several manufacturers recorded stronger BEV penetration inside their own sales mixes. Mercedes-Benz Group, Hyundai-Kia, Renault and Toyota all registered notable increases in the share of BEVs sold. Conversely, BYD's product mix appeared to shift toward plug-in hybrids, according to Jefferies' observations.
Looking ahead, the analysis highlights EU CO2 compliance as the primary force expected to shape BEV sales across Europe between 2025 and 2027. Jefferies notes that meeting the regulatory requirement for a 12% reduction in fleet CO2 emissions will likely necessitate a further expansion in BEV penetration, estimated at roughly 5 to 7 percentage points, even after accounting for hybrids and other regulatory offsets.
Regulatory mechanics changed earlier in 2025: amendments to EU compliance rules introduced a three-year compliance window for automakers, replacing the prior annual requirement. The amended rules, confirmed in a June 2025 vote after an earlier amendment on February 26, 2025, allow manufacturers to average CO2 emissions over the 2025-2027 period. That three-year averaging lets automakers offset shortfalls in one or two years with overperformance in others, altering the timing and smoothing of compliance-driven fleet composition decisions.
Jefferies' findings draw a picture of accelerating electrification in European passenger vehicle sales, with policy incentives and regulatory obligations jointly influencing manufacturers' and consumers' behavior. The analysis points to continued shifts in product mix across brands as the market adjusts to these combined forces.
