The nation's largest automakers generally reported strong March sales totals in their latest round of monthly numbers.
Ford Motor Co. said that sales increased 9 percent last month compared to March 2015. Sales of Ford vehicles climbed by nearly 8 percent, while its luxury Lincoln brand saw an 11 percent jump.
Ford said that its SUV sales recorded the best March in 15 years and that sales of its F-Series pickups were the best in a decade.
Fiat Chrysler, meanwhile, reported an 8 percent sales increase on the back of double-digit increases among its Jeep, Dodge and Ram Truck brands.
Jeep, with a 15 percent increase, saw its best March sales in history, while Dodge and Ram each grew by 11 percent compared to the same month last year. The Chrysler brand, however, saw a 13 percent sales decline and Fiat fell by 24 percent.
General Motors reported a sales gain of just less than 1 percent in March, although the company attributed the modest total to reduced rental units and said that retail deliveries were up by 6 percent.
Among GM's brands, GMC led with a nearly 7 percent sales increase, followed by a 1.4 percent increase by Chevrolet. Buick sales fell by more than 11 percent and Cadillac declined by 5 percent.
Among foreign automakers, Nissan sales increased by 12.7 percent as its flagship division recorded its best March in history. The Infiniti sales line also saw a double-digit sales increase.
