DETROIT — With a month still to go, 2015 almost certainly will be the U.S. auto industry’s best sales year ever as consumer confidence, easy credit, tumbling gas prices and the need to replace old vehicles have created the equivalent of a surfer’s perfect wave.

Analysts are forecasting that sales for all of 2015 will exceed 17 million and possibly break the previous record of 17.4 million set in 2000.

For the third consecutive month, the adjusted annual selling rate exceeded 18 million, coming in at 18.2 million in November.

Fiat Chrysler Automobiles’ sales rose 3 percent, Ford’s edged up 0.4 percent and General Motors reported a 1.5 percent increase despite two fewer selling days.

Barring an unforeseen economic calamity this month, 2015 industry sales almost certainly will exceed the current record, and there’s a kicker: Next year could be even better.

The only bad news fell mostly on Volkswagen, which saw sales of its mainstream VW brand plummet nearly 25 percent. November was the first full month in which the impact of the German automaker’s cheating on diesel emission tests was reflected in showrooms.

“The fundamentals are just really strong right now,” said Stacy Doyle, senior auto analyst with TrueCar, which provides pricing information to car buyers.

The increasing likelihood of a quarter-point interest-rate hike this month by the Federal Reserve is not dampening consumers’ spirits. The prospect of a rate increase may have helped boost November sales.

“Many consumers may also be sensing the inevitable hike in interest rates and looking to make a purchase before financing costs rise,” said Karl Brauer, analyst with Kelley Blue Book.

Nissan reported a 3.8 percent sales increase last month, led by its Rogue compact crossover (up 49.8 percent) and larger Murano crossover (up 45.2 percent). Toyota’s sales rose 3.4 percent, helped by its strongest Black Friday weekend in eight years.

Honda sales dropped 5.2 percent, as sales of its Acura luxury brand tumbled 17.6 percent.

At Fiat Chrysler Automobiles, Jeep sales surged 20 percent from November 2014 as the Grand Cherokee, Compass and Patriot all posted increases of more than 10 percent. Sales of Chrysler and Dodge fell 12 percent and 8 percent, respectively. Ram sales edged up 1 percent while Fiat sales fell 3 percent.

It was the 68th consecutive month that the Detroit-area automaker reported a sales increase from the year-earlier month.

Ford sales were up slightly, as a 10.4 percent jump in sales of the F-Series pickup offset declining sales of Ford’s passenger cars and SUVs.

“We saw strong customer demand for our cars and SUVs with the latest technology and sold a very rich mix in November,” said Mark LaNeve, Ford’s U.S. vice president of marketing, sales and service. “F-Series and commercial vans also were very strong, with an 18 percent gain for the month and our best November sales performance for Ford trucks in eight years.”

Sales of the Transit and Transit Connect vans nearly doubled from a year earlier in November.

At GM, increases of 4.8 percent at Chevrolet and 1.8 percent at Cadillac more than offset falling sales at Buick (down 16.6 percent) and GMC (down 1.90 percent).

“The phenomenal growth of crossovers in a record-setting market is the biggest sales story of 2015,” said Kurt McNeil, GM’s U.S. vice president of sales.

TrueCar, which provides consumer information about car and truck pricing, reported that the average new vehicle sold for $32,966 in November, up slightly from a year earlier.

Ford officials said the average transaction price of F-Series pickup trucks was $42,800 in November, up $2,700 from a year earlier.

Erich Merkle, Ford U.S. sales analyst, said the average pickup truck on U.S. roads is 11.8 years old. So demand driven by the need to replace aging trucks won’t weaken in the near future.
