Next up will be the venerable three-valve 4.6l V8 from the Explorer. This engine will be not modified in any way from its Explorer application so the power numbers will remain 292hp, and 300ft.lbs of torque. This engine is at its final years of production, and will be dropped shortly after the engine lineup is completed in the 2010 model year.
The third V8 at launch will be a new version of the 5.4l V8. Mostly using the Expedition setup, Ford has reworked the engine for more power, torque, refinement, and efficiency. The final numbers were not revealed yet, but 325hp and 380ft/lbs of toque is a reasonable expectation.
The first post-launch change in the powertrain lineup will occur in the first weeks of 2009. As a Job2 change, Ford will add a 6.2l V8 engine. This will be the first member of the BOSS family, and while the engine is still in testing, it is expected to be rated at around 425hp. This engine will be officially revealed and released a couple months prior in the 2009 Lincoln Navigator.
Final major change in the engine lineup will come with the launch of the 2010 model year of the truck in the summer of 2009. A new 4.4l V8 diesel engine and a TwinForce 3.5l V6 will be added, and, as mentioned above, the 4.6l V8 will probably be dropped. The diesel is a larger version of the 3.6l Lion V8 diesel Ford developed with France’s Peugeot/Citroen (PSA) automaker, and will deliver around 315hp and 520ft.lbs of torque. The Twin Force engine will be positioned as a V8 alternative with better fuel economy. Using twin turbochargers, direct injection, and twin independent camshaft timing, the engine will deliver about 400hp and 400ft.lbs of torque at 1500rpms.
It is unfortunate Ford will not launch the truck with the full engine lineup, and it will likely hurt the sales some; but with the rapid rollout of the remaining engines the damage should be minor. Moreover, Ford has a final ace up its sleeve; in the 2011 or 2012 model year, Ford will add a monster of an engine: a TwinForce version of the 6.2l V8 – delivering more than 650ft.lbs of torque and around 500hp. The new engine will deliver performance equal to, say, a Chrysler SRT-10, but with a smaller engine and better fuel efficiency. Like with the 2008 Super Duty, Ford is not playing around with the truck and aiming squarely for the “class leading” designation. We will see the truck at Detroit Auto show in January, and Job1 is on August 8th, 2008.
