Editor's note: Some earlier versions of this story listed the wrong age for Susan Docherty, who turned 47 on Sept. 12.
DETROIT -- General Motors Co. named engineering boss Mark Reuss president of GM North America while new sales chief Susan Docherty adds service and marketing roles in the automaker's latest management shake-up.
Docherty, 47, tapped as vice president of sales in October, has been put in charge of marketing GM's four remaining U.S. brands and will lead the service and parts organization as well, Chairman and interim CEO Ed Whitacre announced today. She reports to Reuss, 46, who two months ago became vice president of engineering.
In addition, Vice Chairman Bob Lutz, 77, keeps his vice chairman title and cedes his marketing duties in once again becoming an adviser on product development and design.
Whitacre's announcement unravels many of the structural changes GM underwent in July after it emerged from Chapter 11 bankruptcy. The moves also heap accountability on Docherty and Reuss, who both advance again after October promotions.
“I want to give people more responsibility and authority deeper in the organization and then hold them accountable,” Whitacre said in a statement.
That makes Docherty the point person for reversing GM's decades-long slide in U.S. market share and restoring luster to the surviving brands -- Buick, GMC, Cadillac and Chevrolet -- tarnished by congressional bailout hearings last year and this year's bankruptcy. GM now commands less than 20 percent of its home market, down from 51 percent a half century ago.
Reuss, 46, returned to North America this fall in the engineering post. He had led GM's Australian unit, Holden, since early 2008. He is the son of former GM President Lloyd Reuss.
