2008 Ford F-450 Super Duty Road Test Ratings

Towing performance is unsurpassed. A commercial-grade chassis (previously available only in cab-chassis form) and all-new 6.4-liter PowerStroke diesel engine combine to allow up to 24,500 pounds to be towed. The extra-wide front axle allow 45 degrees of steering lock, giving the F-450 a tighter turning circle than all other long-wheelbase dual-rear-wheel trucks.

Considering the tow rating, the interior is well-appointed and the seats are comfortable. Longer rear leaf springs make the unloaded ride better than last year's F-350, but it's still stiff without a trailer attached. Consider something else if extreme heavy-duty towing isn't your intention.

The standard 8-foot bed can carry over 6,100 pounds of payload. Air-conditioning, audio systems and other interior controls are straightforward. Plenty of interior storage is available via a large center console and generous bi-level door pockets. An innovative bed step folds out of the tailgate.

Outside, the F-450 looks every bit the part of a heavy-duty hauler. But inside, the tough truck theme is a bit over-the-top. Assembly quality is about average for such a truck.
