DETROIT - Ford Motor Co. will launch its F-150 pickup with a diesel engine in 2008 or 2009, a former top executive confirmed. If it arrives on time, the F-150 probably will be the first light-duty pickup with a diesel in North America. Dave Szczupak, who retired last week as Ford's vice president of manufacturing for the Americas, said the F-150 will get a version of the 3.6-liter V-8 diesel used in the Land Rover Range Rover SUV sold in Europe.
