Car registrations plunged in March, according to figures from industry body the Society of Motor Manufacturers and Traders (SMMT).
Preliminary data shows the UK new car market shrank by 15.7% last month compared with 2017.
Demand for diesel vehicles fell 37%, but demand for petrol was flat and that for alternative fuel models rose 5.7%.
March 2017 was a record month as customers bought new vehicles ahead of a change in Vehicle Excise Duty.
New car sales fell for the first time in six years in 2017, with a 5.7% decrease to about 2.5 million vehicles.
Demand for diesel cars plunged by 17% last year, meaning the pace of decline for such vehicles in March has more than doubled.
