New car registrations dropped by 4.1% in April, only 161,000 care were registered compared to 168,000 in April 2018, the Society of Motor Manufacturers and Traders (SMMT) said.
Business and private registrations were down by 10.3% and 32.7% respectively, and fleet sales were up by 2.9% during the month.
Diesel and petrol vehicles were down by 3.0% and 9.4% year-on-year respectively during April.
Electric and hybrid sales increased by 12.7% and took a 6.4% share of the market.
Mike Hawes, chief executive SMMT said, “While it’s great to see buyers respond to the growing range of pure electric cars on offer, they still only represent a tiny fraction of the market and are just one of a number of technologies that will help us on the road to zero.
“Industry is working hard to deliver on this shared ambition, providing ever cleaner cars to suit every need.
“We need policies that help get the latest, cleanest vehicles on the road more quickly and support market transition for all drivers.
“This includes investment in infrastructure and long-term incentives to make new technologies as affordable as possible.”
