Ireland registered 121,979 new cars from January to August 2026, up 5% on the same period of 2025, according to SIMI. August added 7,811 registrations, up 3%. Electric cars are the story of the year: 32,079 battery-electric cars have been registered so far in 2026, up 55%, and electric now accounts for 26.3% of the year's registrations, ahead of petrol-electric hybrids on 24.14%, petrol on 20.09%, plug-in hybrids on 14.85% and diesel on 12.56%. August's electric registrations were 2,265, up 7%. The Toyota RAV4 was August's best-selling car and the Volkswagen ID.4 the best-selling electric car. Irish registrations cluster in January because the number plate carries the year, so most of 2026's volume is already in. This dashboard covers every SIMI year since 2010, with county, brand and fuel breakdowns. Last verified on 28 September 2026; SIMI publishes September in early October.
