Ford Super Duty trucks out-sell the heavy-duty pickups from Chevrolet and Dodge combined. Ford has improved them for 2003. Ford Super Duty trucks are very roomy, with comfortable and spacious seats and plenty of hip and shoulder room. A new 6.0-liter diesel engine is available for 2003 models that's cleaner, more efficient, and more powerful than the outgoing 7.3-liter diesel. Four-wheel antilock disc brakes, which are standard, provide excellent driver feedback and smooth, undramatic stops. New and revised powertrains make Ford's heavy-duty pickups more capable and, therefore, more attractive. The new 6.0-liter turbo-diesel is drawing rave reviews and is available with a new five-speed automatic.
