The CCFA French automakers lobby group expects a tough end of the year after new-car sales fell 9.5 percent in October.
Registrations dropped to 171,049 from 188,987 in October 2019, the CCFA said in a statement.
October had one less selling day than the same month last year. Adjusted for comparable figures, the monthly decline would have been 5.4 percent.
The CCFA warned that the rest of the year will be difficult after dealerships were ordered to close for walk-in sales during the government's latest national lockdown to reduce the spread of coronavirus.
The decision by President Emmanuel Macron to shut dealerships to walk-in customers until Dec. 1 and the impact of the government's reducing incentives for electrified cars and penalizing high CO2 emission models means "we are in for a difficult year end," CCFA spokesman Francois Roudier told La Tribune newspaper.
New-car sales during October returned to traditional levels for the month, Roudier told the paper. "Business was healthier than a typical year end, with higher demand by private customers and smaller rebates," he said.
Order level was very good in early October but deteriorated before the end of the month, Roudier said.
Registrations in the first 10 months are down 27 percent to 1.24 million vehicles.
