DETROIT - General Motors has promoted Jim Campbell to general manager - Chevrolet, effective Dec. 9. In his previous assignment, Campbell was general manager of GM's Fleet and Commercial Operations. 

A new general manager of GM Fleet and Commercial Operations is expected to be announced shortly.

Campbell has overseen GM's Fleet and Commercial Operations since Feb. 1, replacing Brian McVeigh, who retired in March.

"Jim has a strong track record of building relationships and partnerships with dealers and customers, and deep Chevrolet experience," said Susan Docherty, GM vice president Sales, Service and Marketing. "His energy, drive for results and willingness to take risks are great assets for leading the growing global Chevrolet brand." 

Before running GM's Fleet and Commercial Operations, Campbell held various positions in field sales, retail incentives, marketing and customer relationship management.  He has played important roles in many product launches including the Chevrolet Impala, Monte Carlo, Colorado, and Corvette. 

Campbell, who joined GM in 1988, replaces Brent Dewar, previously vice president global Chevrolet.  Dewar has elected to retire effective April 1, 2010 to dedicate more time to his family and to pursue personal interests. Until then, Dewar will work closely with Campbell to ensure a smooth transition at Chevrolet and also will be on a special assignment supporting Mark Reuss, GM president North America, in his new role.

"During his 31 years with GM, Brent made a difference in multiple assignments, including key roles in Brazil and Europe, launching the award-winning American Revolution campaign and applying his environmental passion to drive the very successful gas-friendly to gas-free marketing strategy," Docherty said.  "We respect his decision to retire early next year to spend more time with his family, and want to thank him for all his contributions.  He will be missed."

In addition to Campbell's appointment, Docherty announced Dec. 10 that Buick GMC General Manager Michael Richards has also elected to leave General Motors to pursue other career opportunities. "A replacement will be announced in the near future," she said in a statement.
