Ford engineers crafted the workhorses in the 2012 Super Duty with the goal of bringing you the toughest hardest-working truck that delivers the reliability and fuel efficiency. We gave the E85-capable 6.2 liter engine bigger pistons bigger intake and exhaust valves and a larger engine bore diameter. Offered on the Super Duty F-450 and F-550 Chassis Cabs the 6.8 liter V10 is the only large-displacement gas engine of its kind available in the Class. And there is the All-New 6.7 liter Power Stroke V8 Turbo Diesel. More power. Class-leading diesel fuel economy. And a lot of it has to do with this six-speed TorqShift automatic transmission. Super Duty has so many options to help get all those jobs finished. From an available Ford Work Solutions to the new available Live Drive Power Take-Off provision. Super Duty continues to innovate with its enhanced Tow/Haul Mode. You already have the best-in-class max payload. The segment-exclusive integrated tailgate step makes it easier to access that payload. The 2012 Ford Super Duty the Best Truck Wins.
