Ford sells more diesel-powered pickup trucks annually than Chevrolet and Dodge combined. Nearly three-quarters of all Ford Super Duty trucks sold are diesel-powered.

The new engine benefits from an innovative development process designed to more accurately reflect how Super Duty customers use their vehicles every day. The team began by collecting real-world data from working Super Duty commercial customers, tracking their daily duty cycles. That data was used to develop durability tests that more closely represented real-world use. To better assure durability, the tests were conducted using the most extreme and abusive conditions and run to five-times the life cycle that the hardest-working truck would ever experience.

"By the time we launch this vehicle," said Dan Davidson, Powertrain supervisor, "the engine will have seen more than 10 million equivalent miles of testing both on the dyno and in test vehicles."

The 6.4-liter Power Stroke Diesel delivers 350 horsepower at 3,000 rpm and 650 lb.-ft. of torque starting at 2,000 rpm and utilizes Ford Clean Diesel Technology, which includes, among other features, a high-pressure, common rail fuel system, Piezo-electric fuel injectors and an advanced diesel particulate filter system to deliver strong performance while reducing particulate output by more than 90 percent and posting emissions numbers on par with gasoline engines.

High-tech, series sequential turbochargers provide improved response and better low-end performance. The unique system uses a small, electronically controlled, smart remote variable geometry turbocharger that comes on at low rpm to provide extra boost at take-off. As rpms increase, the larger fixed turbo joins the smaller turbo to boost power through the middle of the torque curve. As optimum speed is reached, the larger turbo takes over. Tests have shown zero-to-60 times of more than a second faster than the outgoing 6.0-liter.

Transmission choices include a six-speed manual with overdrive or a TorqShift five-speed automatic. The powertrains use a new unique mounting system that better isolates the powertrain and reduces vibration. Both two- and four-wheel-drive models will be available on the 2008 Super Duty.



New interior provides quiet comfort and improved ergonomics

The all-new interior builds on the successful tough luxury design established by the Ford F-150 and advanced for Super Duty, increasing capability, quietness and refinement to levels never before available in Super Duty's segment.

"We know people are spending more time in their trucks, and this is especially true for the Super Duty customer," said Poore. "The truck is their office. It's where they do their business. It's important to not only meet their capability needs but also the comfort and styling needs as well."

The sharp, modern design features all-new materials and includes luxury touches like contrast stitching on the seats and rich, Chaparral leather on the King Ranch. Like the exterior, Super Duty's interior was designed to be functional and capable while still delivering a high level of quality and craftsmanship with a luxurious look.

Designers combined rich surfaces with elements borrowed from high-end power tools and butcher block-style wood accents to define the tough-luxury interior.

"Think of it like a modern kitchen, in a way," said Pat Schiavone, Super Duty chief designer. "A kitchen can be very stylish and look very expensive, but it also must be very functional. It was that kind of thinking that drove tough luxury."
