Ford Motor Co. on Jan. 3 reported an 8.8% decline in U.S. sales for December 2018 on a year-over-year basis.
The carmaker sold 220,774 vehicles, compared with 242,049 vehicles in December 2017.
Ford's car sales dropped 27.8% year over year in December to 34,950 vehicles. The Michigan-based automaker also posted a 3.8% year-over-year decline in its Ford brand trucks to 106,599 units in December.
Meanwhile, Ford's SUV sales fell 4.4%. Sales of Ford's F-Series trucks line declined 1.8% during the month to 87,772 vehicles.
In 2018, the company sold 2.5 million vehicles.
Ford executives said during a Jan. 3 conference call that the company will stop reporting monthly sales and move to quarterly sales reporting like rival General Motors Co.
"Some of our key competitors have moved to a quarterly basis, so we feel kind of transitioning to more of an industry standard," said Mark LaNeve, Ford's vice president of U.S. marketing, sales and service.
General Motors said in April 2018 that it will no longer publish monthly vehicle sales in U.S. and instead will switch to quarterly reports because monthly vehicle sales are subject to more volatility than quarterly sales.
Ford's shares were up 0.13% to $7.91 in afternoon trading.
