Last month, we reported that Ford would be offering F150 buyers the option of a diesel powerplant for the 2009 model year. At the time, it wasn't a stretch to think that an oil-burner would someday find its way under the hood of the Expedition, since both vehicles share the same front clip. That assumption proved true, when the Expedition's chief engineer, John Viera, told Automotive News that a diesel would be offered by the end of the decade.

Although a timeframe wasn't specified, expect the diesel-equipped Expedition to launch around the same time as its pickup truck counterpart, likely sporting a larger version of the 3.6-liter V8 shared by Land Rovers across the pond.

Viera points to the success of the diesel-powered Excursion, before it was discontinued, and the fact that any vehicle sold with a fuel-efficient engine is a hot commodity on showroom floors. The possibility of a diesel version of the Lincoln Navigator was also mentioned.
