Motoring with truck beds and pulling up to 18,000 lbs., we were most pleased with the way the trucks held gear when pulling heavy loads and descending steep hills, requiring little to no braking. Also impressive is the cleaner, quieter common rail diesel engine with dual stage turbos for a relatively seamless feed of power and improved low end performance. Ford say that this new powertrain is more than one second faster in zero to sixty times than the previous generation, and while we were unable to test that claim, we found it to be quite responsive to throttle command for a large vehicle. Braking, on he other hand, felt like a weak point during our limited drive, the pedal lacking enough feel and the truck seeming to take its time. Road conditions at the time were wet and icy, however, which played into the experience.
