During an interview with Automotive News, Mark Fields, Ford's U.S. division president, said that the automaker would not be offering diesels in any of its passenger cars in the near future. For the time being at least, Ford's only diesel-equipped vehicles will be in their flagship F-series line of pickups.
The reasons behind not bringing an oil burner to America are varied, but the primary hurdle is the cost of engineering an engine that would meet the U.S.'s stringent emissions standards. This is the same argument currently employed by Toyota, when asked about its own pursuit of diesel technology.
Instead, Ford will focus on high-tech gasoline mills, utilizing turbocharging, direct injection and hybrid powertrains, which will increase fuel economy and in some cases, performance.
