As is well known by now, Ford and Navistar have parted ways and the Blue Oval is developing diesel engines in-house to replace the PowerStroke lumps still being used. Slated to appear in Ford's trucks by 2011, the new oil burner code-named Scorpion is a 6.7-liter V8 with a host of innovations, some of them seemingly borrowed from cross-town rival GM.
International and Ford haven't been the best of friends lately, with the two companies sparring over compensation for the Powerstroke 6.4L. International stopped making the engines in protest earlier in the year, but this time the union has walked out on International. Even with the strike, Ford hasn't yet suspended production of the Super Duty at its Louisville plant. If the strike lasts more than a few days, however, the blue oval will simply run out of parts with which to build the big truck.
