AUBURN HILLS, Mich. — In an e-mail to employees Friday, Chrysler CEO Tom LaSorda said one of the benefits of being a private company was the speed with which the automaker could act. Employees got a taste of that speed Monday, when in one decisive sweep LaSorda was demoted and the former head of Home Depot was tapped to lead Chrysler.

"The new Chrysler has the opportunity to prove that the private business model can thrive in this industry," said Bob Nardelli, who left The Home Depot Inc. in January after a shareholder rebellion over his outsized pay. Chrysler's new board named Nardelli chairman and chief executive; LaSorda was given the No. 2 spot.

It was always clear Chrysler would be a different animal under its new owner, the private equity firm Cerberus Capital Management. It no longer has shareholders, so it isn't required to release earnings or executive compensation figures.

But Monday's announcement underscored that things won't be the same with Chrysler in the hands of the secretive Cerberus, which took industry-watchers by surprise with Nardelli's appointment. Cerberus had previously said it had no plans to change Chrysler's management team.

"You have to wonder whether or not Cerberus is trying to take Chrysler in a different direction," said Patrick O'Keefe, president of O'Keefe and Associates, a turnaround consulting firm in Bloomfield Hills.

Nardelli said he plans to proceed with LaSorda's restructuring plan, which includes cutting 13,000 hourly and salaried jobs in North America by 2009. Nardelli said he wants to help the company focus its efforts and offer his energy and enthusiasm

"It's not about creating a new strategy. They've got it," he said. "I'm confident that we'll continue the momentum of Chrysler's recovery."

For his part, LaSorda said Nardelli is a strong manager who has helped companies grow. At Home Depot, he increased profits and revenues, while as an executive at General Electric Co. he was known for cutting costs and improving labor relations.

"He's always been a winner, every business," LaSorda said. "Leave the egos at the door. Let's turn around this company."

It marks the second time in less than a year that an outsider has come to the rescue of one of Detroit's struggling automakers. Ford Motor Co. named former Boeing Co. executive Alan Mulally as its president and chief executive in September.

Aaron Bragman, an auto industry analyst with the consulting firm Global Insight, said Detroit is in need of outside help as it tries to reverse its fortunes. Last month, foreign brands captured more than 50 percent of the U.S. market share for the first time ever.
