Addressing its glaring problem of an empty product pipeline, Chrysler will do a speedy makeover of at least five models by mid-2011, along with introducing the 2011 Jeep Grand Cherokee and redesigned Chrysler 300 that year, as part of a five-year plan reportedly being submitted to the automaker's board by Fiat CEO Sergio Marchionne on Friday. The Detroit Free Press reports Marchionne wants makeovers accomplished within a quick 18 months on the Chrysler Town & Country and Dodge Caravan minivans; the Dodge Caliber, Jeep Compass and Jeep Patriot compact crossovers; and the Chrysler PT Cruiser, which Fiat revived from the to-be-killed list. The Fiat 500 minicar will be built at the Toluca, Mexico, plant that also assembles the PT Cruiser, for a mid-2011 U.S. introduction, the newspaper reported.
