European car registrations fell 5.2% in March, led by Nissan, Ford and Fiat Chrysler, according to data published today by auto industry association ACEA.
Sales fell to 1.84 million cars last month across the European Union and European Free Trade Area, paring first-quarter growth to 0.6%, the Brussels-based group said.
"Momentum is starting to slow in some markets and especially in the UK," ACEA said in a statement.
Nissan's sales tumbled 16.3% last month, with Ford down 14.6% and Fiat Chrysler 8% lower as the Fiat brand sagged 12%. This more than offset a 42% surge in Jeep sales.
Volkswagen Group sales were little changed, while Renault fell 3.2%.
France's PSA Group recorded a 1.4% gain for its Peugeot unit and a 3.7% decline for Citroen.
