The second-generation Super Duty was initially slated for release in the 2007 model year. However, due to quality concerns, the launch was postponed to the 2008 model year. This iteration introduced a new 6.4 L (390 cu in) Power Stroke diesel V8 engine, equipped with piezoelectric fuel injectors and sequential turbochargers, replacing the previous 6.0L Power Stroke single-turbo diesel V8. The upgraded engine delivers 350 hp (260 kW) and 650 ft⋅lbf (880 N⋅m) of torque. The vehicle was first unveiled at the Texas State Fair in 2006, with Ford commencing order placements in January 2007. The first 2008 F-450 pickup was delivered to a customer in Muskegon, Michigan, in February 2007. The interior layout near the dashboard retained its position similar to the previous generation but was adjusted slightly to the right and positioned more directly below the radio. This generation maintained the Ford TowCommand trailer brake controller and four auxiliary upfitter switches. Enhancements included an optional concealed slide-out step and a swing-up hand grab bar integrated into the rear tailgate, facilitating easier access. Ford also introduced the "Rapid-Heat Supplemental Cab Heater" as an option, specifically designed for use with the diesel engine and TorqShift automatic transmission. This feature quickly warms the cab to a comfortable temperature in colder conditions until the engine reaches adequate heating capacity. The interior of the Super Duty underwent a comprehensive redesign, featuring a new instrument cluster with an enhanced message center, mirroring the aesthetic of the 11th generation F-150 (2004–2008). Updates included a new steering wheel, center dash bezel, interior door panels, and seat trim. New technological additions were Sirius Satellite Radio, a 3.5 mm auxiliary audio input jack, a premium audio system with an external amplifier and subwoofer, and a GPS navigation system with a touchscreen display. In 2009, select trim levels began offering the Ford SYNC entertainment system, which included Bluetooth hands-free calling, wireless stereo audio streaming via A2DP, and a USB port. The year 2010 marked the final model year for the 6.8-liter V10 engine in the F-250 and F-350, as well as for the dual-rear-wheel configurations in short bed models.
