Ford Motor Co. introduced its 2015 F-series Super Duty lineup at the Texas State Fair in Dallas. Expected to hog the limelight is the carmaker’s improved 6.7-liter Power Stroke V-8 turbodiesel that will have its debut next spring. The upgraded 6.7-liter Power Stroke V-8 boasts of producing greater figures than the current version’s 400 hp of output and 800 pounds-feet of torque.
The improved engine receives new GT37 turbocharger with a larger 88-millimeter compressor wheel, replacing the previous GT32. Ford said in a statement that the larger compressor forces more air into the cylinders, thereby improving performance, especially at high altitudes. Ford says that the new turbo, new high-pressure fuel pump and fuel injectors help improve the Super Duty's fuel delivery system. Power Stroke diesel accounts for around two-thirds of Ford's Super Duty customers.
The improved 6.7-liter Power Stroke V-8 turbodiesel will only be available in Super Duty pickups with the current Power Stroke powering chassis cab models. Meanwhile, Ford disclosed that it has recently installed its 500,000th 6.7-liter Power Stroke diesel in a truck at its Kentucky Truck Plant in Louisville. Ford introduced the Power Stroke 2010 for the 2011 model year.
Ford is also showing an updated version of the Super Duty King Ranch edition with a Texas theme and a refreshed F-450 Super Duty at the Texas State Fair. Among the enhancements made to the F-450 include upgraded rear driveline U-joints and upgraded suspension including new rear leaf springs, front and rear stabilizer bars and shocks. It also boasts of stronger steering gears and linkages and increased fifth-wheel and gooseneck trailer capacity.
