* Rising gasoline prices could boost small-car market
* But what happens if gas prices fall again?
* Rising commodity prices could be passed on to consumers
DETROIT, Jan 13 (Reuters) - With U.S. gasoline prices poised to revisit the $4-plus per gallon peak hit in 2008 just before the recession, sales of new smaller cars introduced since then would seem assured.
But as analysts and executives said at the Detroit auto show this week, the only sure thing is that today’s forecasts are wrong -- it is anyone’s guess by how much.
The wild fluctuations in the price of gasoline and of the materials that make up the thousands of car components such as steel, aluminum, copper and platinum can wipe out years of design and manufacturing planning within days.
In the summer of 2008, demand for small cars such as the Toyota Corolla, Honda Civic and Ford Focus far outstripped the immediate inventory as gasoline prices shot higher.
However, a quick pullback in gas prices as the deepest economic downturn since the 1930s took hold left newly built small cars to languish on dealer lots.
"We do believe at Ford that the price of gasoline is going to march upward over time," Ford Motor Co F.N Executive Chairman Bill Ford said on the sidelines of the Detroit auto show. "And we've built our whole entire strategy around that."
The rise in gasoline prices RBc1 has been slower thus far than in 2008 -- when it jumped 32 percent from January to $4.11 per gallon in July, then fell back to $1.65 by year end.
The average U.S. gas price is more than 25 percent below where it was then. Still, executives say they are already seeing a switch to smaller vehicles.
"We're seeing consumers quickly shift back to a higher mix of fuel-efficient cars and now trucks are actually starting to slow down," said Bob Carter, U.S. market brand chief for Toyota Motor Co. 7203.T "Sixty days ago, we found the opposite happening."
FACTBOX-Winners and losers impacted by commodity
Commodity costs pose risks to German trade -BGA:
World commodity prices poised to gain on rising yuan:
Strengthening yuan and impact on commodities:
Some in the industry predict a booming market for smaller vehicles, while others point out that the surge during the last gas price spike evaporated as soon as prices started to slide.
Others still warn that the higher cost of key commodities, primarily rare earths and metals, will be passed on to consumers at a time when the industry is just starting to work its way back from the slump that forced General Motors Co GM.N and Chrysler FIA.MI into government-led bankruptcy in 2009.
"The costs will be higher," said Matthias Mueller, CEO of German luxury automaker Porsche. PSHG_p.DE "But at the end of the day, all of our competitors face the same problem as us."
SUMMER OF DISCONTENT
If anything could sum up the challenges of selling smaller cars in the U.S. market, it would be the gas spike of 2008. Many Americans abandoned a long-standing love affair with gas-guzzling SUVs and trucks to buy cars as oil CLc1 made its historic run to $145 per barrel. It is around $92 a barrel now.
Now there are signs that consumers are downsizing again with gasoline at a national average of $3.09 as of Jan. 11, according to the U.S. Energy Information Agency.
“We are starting to see some segment shifts,” said Jim Farley, global head of marketing and sales at Ford.
Customers expressed outrage when the price hit $3.80 in 2008, but with gasoline prices rising more slowly this time, the “tipping point is likely to be higher,” Farley said.
Mike Jackson, CEO of No. 1 U.S. car retailer AutoNation Inc AN.N, said he believes that point is significantly higher, probably in the $4.50 to $5 range.
“Every time you have one of these spikes, it moves upward the freak-out number,” Jackson said. “The freak-out number in the summer of ‘08 was $3.50 to $4.”
Toyota’s Carter said gas prices could hit $3.50 this year, but reach $4 in some markets with higher taxes like California. The average California price this week was $3.33 per gallon.
Some automakers are banking on a bright future for small cars. Fiat North American brand chief Laura Soave expects the U.S. small car market to more than double in size by 2014.
But what happens if gasoline prices fall again?
Bill Ford maintains that the company his great-grandfather founded has hit on the right solution by launching a global compact platform to underpin vehicles that are fully electric, hybrids or equipped with fuel-efficient gasoline engines.
“If demand is less than we expect, we can just ramp up production for some of the more conventional engines,” he said.
The prices for metals and rare earths have also been on the rise, posing another conundrum for the industry: what proportion of those costs can automakers pass on to customers?
“I think everyone in the industry is in a very competitive position so is it purely a pass through?” GM North America President Mark Reuss said. “I don’t think so.”
But whether or not automakers can pass on those costs, some executives say it is inevitable consumers will pay more for new vehicles. Automakers are looking at using more magnesium and aluminum which are lighter than steel but far more expensive to reduce vehicle weight and improve fuel economy.
“More and more consumers are warming up to the idea of the case that the vehicle might cost a little bit more,” said Fred Diaz, head of Chrysler’s Ram truck brand. “But in the long-run, they’re going to make out ahead because of the fuel efficiency aspect of it.” (For more on the Detroit auto show: [ID:nN09216892]) (Additional reporting by Ben Klayman, Deepa Seetharaman and Kevin Krolicki, editing by Matthew Lewis)
