General Motors Vice Chairman Bob Lutz -- the Brett Favre of the automotive industry -- says he is considering retirement. Again. Speaking today on the sidelines of the Geneva Motor Show, the septuagenarian told Reuters: "The reason I am giving it active consideration this time is because I honestly feel I can look back with satisfaction and say the team I was privileged to lead in product development has actually achieved more than what I would have hoped for." Lutz said in 2007 he'd consider retiring around pending release of the Chevy Volt. Last year he said he'd retire by the New Year, but in July then-CEO Fritz Henderson gave him a new role and kept him from walking away. There's no word on whether Lutz has had talks with the Vikings. Meanwhile, the Detroit Free Press reports GM could announce another management shakeup as soon as today. It's expected Susan Docherty, vice president of sales and marketing, will lose her sales duties to Mark Reuss, who took over as President of General Motors North America three months ago.
