Wheelies: The Mutual Aid Society Edition Bloomberg reports that General Motors may acquire up to 7 percent of the French conglomerate PSA Peugeot Citroën.

G.M."s European unit has been unprofitable for years, and Peugeot recently announced that its net income for 2011 fell nearly 50 percent from a year earlier. Bloomberg Dave Rand, the former head of advanced design for G.M. who joined the Chinese automaker Changan last October, has resigned from the company, Car Design News reports.

His departure follows that of Ken Ma, the company's former vice president for design.
