The second-generation Super Duty was originally going to debut for the 2007 model year, but quality issues pushed it back to the 2008 model year. It receives an all-new 6.4 L (390 cu in) Power Stroke diesel V8 with piezoelectric fuel injectors and sequential turbochargers to replace the 6.0L Power Stroke single-turbo diesel V8. The new engine produces 350 hp (260 kW) and 650 ft⋅lbf (880 N⋅m) of torque.[14] The vehicle had its first official showing at the Texas State Fair in 2006. Ford started taking orders in January 2007. The first 2008 F-450 pickup sold to the public was delivered to Randy Whipple of Muskegon, Michigan, in February 2007.
