DETROIT — After a 26-year absence, Fiat dealerships will be returning to the United States — but in a small way, The New York Times reported.

Chrysler said Tuesday that it planned to set up about 200 outlets by the end of the year to sell the Fiat 500, an Italian designed subcompact. The dealerships will be run by existing Chrysler dealers and in many cases located on the same property, but they will have separate showrooms and employees.

The strategy runs counter to a general trend of consolidating multiple brands into one showroom. It also requires dealers to commit significant resources to a lineup that initially has a single model. A convertible, the 500 Cabrio, is scheduled to arrive in 2011, followed by a battery-powered 500 in 2012, but Chrysler has not revealed plans to expand Fiat beyond that.

BMW used a similar approach to successfully reintroduce its Mini brand to the United States nearly a decade ago, requiring dealers to build auxiliary showrooms to sell the Mini Cooper. But investing in an expansion for what analysts consider to be a niche model, at a time when auto sales are depressed and many dealers are struggling, is a gamble.

“If I were a dealer, I would be somewhat reluctant to make that investment,” said Erich Merkle, an automotive analyst and president of Autoconomy.com in Grand Rapids, Mich. “You have to go and build a new facility to sell a brand that really is going to take a considerable amount of time to get any kind of volume.”

A Chrysler spokesman, Ralph Kisiel, said the company intended to have Fiat dealerships in 125 markets in about 41 states. He said most would be concentrated in metropolitan areas where small cars were already popular and where demand was expected to increase.

Executives sent letters this week to all 2,320 Chrysler, Dodge, Jeep and Ram dealers inviting them to apply for a Fiat franchise. Fewer than 10 percent will be selected, and the locations will be announced in September, Chrysler said.

“We want our best performing dealers to get these franchises,” Kisiel said, adding that Chrysler has focused on “markets that have a high number of small-car registrations.”

The Fiat 500 is a major piece of Chrysler’s efforts to diversify a lineup that has relied heavily on trucks and sport utility vehicles, hurting sales as American consumers began seeking more fuel-efficient alternatives. The company plans to build more than 100,000 of the vehicles a year at a plant in Mexico, sending half to the United States and half to South America.

Access to a dealership network in the United States was a major reason that the Italian carmaker’s chief executive, Sergio Marchionne, pursued a takeover of Chrysler. The 500 fills a hole in Chrysler’s lineup, but also gives Fiat a quick way to re-establish itself in the United States.
