SIMI published the May 2026 passenger-car bulletin on 2 June. The headline numbers are the strongest single-month growth Ireland has seen in 2026: 8,068 new car registrations, up 38.58% from 5,822 in May 2025 (RTÉ, 2 June 2026, Irish Times, 2 June 2026).
Battery-electric: 2,335 in May, more than double last year
The standout signal is electric. 2,335 fully battery-electric cars were registered in May 2026, against 1,086 in May 2025, a year-on-year jump of +115%. The acceleration is not the product of a thin base period; May is structurally a top-five plate-change month.
YTD 2026: 83,038 cars, BEV share at 23%
The year-to-date picture is now consistent with a full-year outperformance of 2025. Total Irish passenger-car registrations through May reached 83,038 units, up 4.7% on the 79,313 logged in the same period of 2025. Battery-electric YTD registrations reached 19,050 units, taking the BEV share of all new car registrations to 23% for the year so far.
That is a significant structural marker. Ireland closed 2025 at an 18.89% BEV share (SIMI). If the pace through May holds, AutoNergy's own projection is a full-year 2026 share comfortably above 2025's.
77% of EV buyers are private consumers
A detail worth flagging: 77% of BEV registrations year to date are private consumers, not fleet or company-car. SIMI attributes the growth to consumers and to incentives. In AutoNergy's reading, that mix is the signal that BEV adoption has moved past the early-adopter and tax-driven fleet cohorts into mainstream household decisions.
Top sellers: Toyota RAV4 and VW ID.4
The single best-selling new car in May 2026 was the Toyota RAV4, per SIMI. The single best-selling electric car in May was the Volkswagen ID.4, edging the Skoda Enyaq and Tesla Model Y in the BEV table. Toyota's hybrid lineup continues to anchor the brand throne; Volkswagen Group's BEV breadth (ID.4 plus Skoda Enyaq plus Audi Q4 e-tron) is the EV-table anchor.
What the rest of 2026 looks like
Three implications, all AutoNergy's own reading. First, if the +4.7% YTD pace holds, the full year would close around 130,000-132,000 cars, ahead of 2025's 124,954. Second, BEV share above 23% YTD puts Ireland in a much stronger position on its 2030 transition goals; the question is whether Ireland ends the year among the leading Western European BEV markets. Third, the consumer-led 77% share of BEV buyers means SEAI grant levels and Vehicle Registration Tax structure are likely to be debated in Budget 2027, as the policy lever is now showing its work.
