The UK’s new car market grew by 8.4% in March, making it the biggest month since records began, according to figures released by the SMMT.
The record performance came as buyers seized the chance to buy cars before the new vehicle excise duty (VED) rates came into force.
As of 1 April, under the new system all new cars, except for those with zero emissions, are subject to an annual flat rate charge.
A total of 562,337 new cars were registered in March, more than double the number in the first two months of the year combined.
Mike Hawes, SMMT chief executive, said: “These record figures are undoubtedly boosted by consumers and businesses reacting to new VED changes, pulling forward purchases into March, especially those ultra-low emission vehicles that will no longer benefit from a zero-rate fee.
“This bumper performance probably means we will see a slowdown in April, exacerbated by the fact there are fewer selling days this year given Easter timing.
“Looking ahead to the rest of the year, we still expect the market to cool only slightly given broader political uncertainties as there are still attractive deals on offer.”
Fleets and businesses were the big contributors to market growth in March, with registrations up 12.6% and 11.9% respectively, though demand from private buyers also grew, with registrations climbing 4.4% to reverse the decline in demand seen during the previous month.
Sales of alternatively fuelled vehicles also increased in March, jumping 31.0%, whilst petrol cars experienced a notable uplift too, growing by 13.2%.
Demand for diesels also increased compared to the previous year, with nearly a quarter of a million buyers choosing them – the most ever in a single month.
