* Ford, Chrysler top analysts' expectations
* GM, Toyota, Honda, Nissan fall short
* Full-size truck sales down at GM
* Analysts mostly upbeat on 4th quarter and next year
U.S. consumer demand for new vehicles cooled slightly in September, as expected, as Ford Motor Co topped analysts' expectations, but General Motors Co fell short.
As automakers reported September U.S. sales results on Tuesday, the industry posted its first year-on-year sales decline in more than two years. There were two fewer shopping days in September, compared with the previous year, and part of the Labor Day shopping weekend fell in August.
Ford's U.S. dealers, bolstered by strong pickup sales, delivered 185,186 vehicles in September, up 5.8 percent from the previous year and narrowing the gap with industry leader GM to a slim 2,000 vehicles last month.
GM, whose September sales dropped 11 percent to 187,195, said that its dealers had a limited supply of full-size pickup trucks. The automaker continued to add new versions of the redesigned 2014 Chevrolet Silverado and GMC Sierra while selling down stocks of the 2013 models.
Silverado sales in September fell 10.8 percent. Its rival, the best-selling Ford F-Series, rose 9.8 percent.
GM said lower retail incentives and fleet sales contributed to its sales decline in September.
One question looming over the U.S. auto industry as it heads into the final quarter of this year is the potential impact of the federal government shutdown on October car sales.
"As long as the underlying economic factors are supporting the business, which we think they will through the end of the year and through 2014, we'll get through this turbulence," said Ken Czubay, Ford's U.S. marketing vice president.
Among the other major automakers reporting on Tuesday, Chrysler Group LLC beat analysts' expectations in September, while Toyota Motor Corp, Honda Motor Co and Nissan Motor Co missed.
Chrysler, an affiliate of Italy's Fiat SpA, said sales were up 1 percent at 143,017, its best September in six years.
Toyota's sales dropped 4.3 percent to 164,457, Honda's declined 9.9 percent to 105,563 and Nissan's fell 5.5 percent to 86,868. All three companies missed analysts' expectations.
Automakers sold 1.14 million vehicles in the United States last month, down 4.3 percent from 1.19 million a year earlier, according to data provided by manufacturers and compiled by Reuters.
SALES RATE FALLS
The annual rate of industry sales fell from 16.1 million vehicles in August to around 15.4 million in September, Morgan Stanley analyst Adam Jonas said on Tuesday in a briefing to clients.
"We see the momentum continuing, certainly not at the breakneck pace we've seen over the last couple of months," said Alex Gutierrez, senior analyst at Kelley Blue Book. "But we believe that our forecast for the year, which calls for 15.6 million units, is still definitely on the table."
Sales by brand, even at Ford and Chrysler, were mixed.
Chrysler's Dodge, Chrysler and Ram brands all reported modest increases in September. Jeep sales fell 5 percent as Chrysler struggled to get the all-new 2014 Cherokee to dealers. Fiat brand sales plunged 24 percent, the first year-to-year decline in 18 months.
Sales of Ford brand vehicles rose 6.3 percent, while Lincoln sales fell 5.1 percent.
Ford said it posted the best September sales since 2006. Chrysler's September sales were its best since 2007.
GM's Cadillac and Buick brands were up in September, while Chevrolet and GMC fell, partly the result of declining truck sales.
Volkswagen AG's U.S. subsidiary said VW brand sales in September fell 12.2 percent to 31,920, while Audi sales rose 6.2 percent to 13,065 and Porsche sales were up 13 percent to 3,093.
Hyundai Motor Co said U.S. sales were down 8 percent at 55,102.
Auto analysts remained mostly upbeat on the fourth-quarter outlook.
"Consumer confidence is relatively high, unemployment ticked down to 7.3 percent in August, and we continue to see increases in home prices and construction activity," Jefferies analyst Elaine Kwei said in a research note.
Barclays analyst Brian Johnson called the expected September sales decline "nothing more than noise."
Average transaction prices for new cars and trucks continued to rise, hitting a record $31,854 in September, according to researcher TrueCar. Prices rose $602 from August as automakers sent more 2014 models to dealers and reduced incentives on leftover 2013 models, TrueCar said.
GM shares were down 0.8 percent at $35.67 and Ford shares were up 1.8 percent at $17.18 on Tuesday afternoon on the New York Stock Exchange.
