I wouldnt want a straight six in my SuperDuty anyways.... not enough highway power.... they might make a little more outta the hole....but every duramax and PSD wasted the dodges when towing down the highway
Ford is developing 4.4L V8 "Lion" and 6.7L V8 "Scorpion" diesels for the F-Series. The engines employ tech developed in Ford's European joint venture with Peugeot, stuff Navistar can only dream of.
The engines will be assembled in Chihuahua, Mexico. The 6.7 makes 400 hp @ 3,600 rpm and 700 lb.-ft. @ 1,600 rpm.
No Cummins in 2010.
I would just like someone to say when the f150 is going to have the diesel as I really want to stay with the 150 but do not want to wait another year for it. I saved up all my pennies to pay cash for this truck and I only want to buy what I want as this is the last time I get a brand new truck. If the scorpion theory is correct maybe worth waiting for.
Ford and Cummins will never be a reality. Ford has had long term contracts with Navistar, and has been working on an in house diesel. The ONLY time Ford has ever had any direct involvement with Cummins, was the brief period of time in which Ford bought and sold some Cummins stock.
