GM announces revised Duramax 6.6L and new light-duty diesel

As noted by Inside Line, Ford decided not to go with the locomotive-inspired theme of the Super Chief concept for its refreshened Super Duty pickups due out this summer. Too bad, as the Super Chief was super cool. Regardless, the new Super Dutes will get bigger and bolder in the front and back, with larger, one-piece headlights that extend down to a one-piece bumper, bigger vents in the grille, quarter panel vents behin

Ford tries to win back Power Stroke customers with cash

Buyers of such engines demand reliability, and the new 6.0L had some rather significant fuel system and induction problems, leading to a large number of service bulletins and even some buy-backs of defective vehicles. The problem has been made worse by the importance of this market to Ford, as it is currently the leader in diesel pickup s
