DETROIT — Chrysler’s U.S. sales rose a surprising 16 percent in November, a sign that the auto industry is on track to beat strong sales numbers from a year ago.

The automaker sold just over 142,000 vehicles last month for its best November in six years, up from nearly 123,000 a year ago.

The company was led by the Jeep brand, which posted a 30 percent increase and its best-ever November sales. The star was the all-new Cherokee small crossover SUV, which notched the rare achievement of sales of more than 10,000 in its first full month on the market.

“That is a big number,” said Jeff Schuster, senior vice president of auto sales forecasting for LMC Automotive, an industry consulting firm.

The Cherokee’s successor, the boxy Jeep Liberty, sold only around 8,000 in its first full month on the market in 2001, Schuster said.

The big sales gain for Chrysler, based in Auburn Hills, Mich., shows that consumers didn’t shy away from auto showrooms last month and that sales likely will remain strong through the end of the year.

Most industry analysts expected Chrysler to post around a 10 percent gain for the month.

All automakers report monthly sales figures on Tuesday.
