The performance marks 10 consecutive months of growth, although registrations remain -21.0% below pre-pandemic 2019 levels.
Large fleet registrations continued to drive the growth, up by 36.9% to 76,207 units, reflecting a regularisation of supply following challenging supply issues in 2022. Registrations to private buyers fell slightly by -0.5% to 65,932 cars, while smaller business fleets registered 3,065 units, a year-on-year rise of 22.5%.
Petrol-powered cars remain Britain's best sellers, accounting for 57.1% of all registrations. Alternatively powered vehicles, however, continue to make up an ever-larger share of the market, with plug-in hybrids (PHEVs) rising 23.0% to reach a 6.2% market share and hybrids (HEVs) growing 22.2% to comprise 12.3% of all registrations. Reflecting the dramatic transformation of the market over the last three years, May saw battery electric vehicles consolidate their position as the UK's second most popular power train. A further 24,513 joined the road during the month, up 58.7% on May last year to secure a 16.9% market share.
Of the new cars registered in May, lower mediums, superminis, and dual purpose were the most popular, comprising 86.3% of the market. There are now zero emission options available in every single segment of the market, with more than 80 models – around a quarter of all new car models available – from which to choose. Furthermore, these new BEVs have an average battery range of 236 miles, well in excess of UK drivers' average weekly mileage of around 100 miles.
While billions of industry investment is delivering choice and growth, however, the speed of the shift needs to accelerate. From January we expect to see the Zero Emission Vehicle Mandate in force, which will set a minimum quota for new battery electric vehicle registrations for every brand. While the models and volumes will be available, ensuring the market demand is there will require action from every stakeholder. A supportive fiscal framework, simplified planning processes, faster grid connections and the provision of a nationwide network of reliable, affordable, and sustainable charge points will give drivers considering the switch the confidence to purchase. Investments are coming but regulated public charger targets commensurate with those for new vehicle registrations would give drivers greater confidence and help accelerate the UK's zero emission transition.
Mike Hawes, SMMT chief executive, said, "After the difficult, Covid-constrained supply issues of the last few years, it's good to see the new car market maintain its upward trend and the fact that growth is, increasingly, green growth is hugely encouraging. Transforming the market nationwide, however, and at an even greater pace means we must increase demand and help any reticent driver overcome any concerns about electric vehicles. This will require every stakeholder – industry, government, chargepoint operators and energy companies – to play their part, accelerating investment to drive decarbonisation."
