DaimlerChrysler AG's Chrysler unit plans more emphasis on its Jeep sport utility vehicles' history and off-road capability as the third-largest U.S. automaker tries to double Jeep sales within a decade, according to Bloomberg News. Chrysler wants to boost the brand's annual sales to 800,000 vehicles from about 400,000 now, said Jeff Bell, the automaker's Jeep vice president. The company will change its advertising slogan back to the mid-1980s theme of "Only in a Jeep" and use a logo that features the seven-slot grill and round headlights found on World War II models, he said.
