Big U.S. automakers including Ford Motor Co. and Fiat Chrysler Automobiles NV (FCA) on Monday reported mixed auto sales in November.

Fiat Chrysler Automobiles reported sales of 181,310 vehicles in November, a 17 percent increase compared with sales in November 2017 of 154,919 vehicles.

Sales were driven by the Jeep and Ram brands which set a variety of records in total, retail and nameplate sales.

Ram brand sales rose 44 percent to a record 57,970 vehicles, the FCA reported. Jeep sales were up 12 percent, and the brand posted a retail sales record of 65,588 vehicles.

"Our dealers saw steady customer traffic throughout the month and especially during the Thanksgiving weekend," said Reid Bigland, FCA's head of U.S. sales.

However, Ford reported November sales fell by 7 percent year over year to 196,303 vehicles, compared with November 2017 sales of 210,771.

Ford truck and SUV sales were off 2.3 percent and 4.9 percent respectively. The automaker's passenger car sales plummeted 19.5 percent last month.

The automaker noted its F-Series truck sales have topped 70,000 units in the United States for nine months this year, continually boosting Ford's average transaction prices.

"F-Series marked a record nine straight months topping the 70,000 truck mark, a consistent performance by a high volume, high margin product unmatched in the industry," said Ford sales chief Mark LaNeve in a statement.
