1997 Dodge T-Rex 6x6 Concept

First seen at the 1997 SEMA show, the Dodge Ram T-Rex 6×6 began life as a factory-stock Ram 3500 1-ton regular-cab pickup truck. Design to be an extreme off-road machine with class-leading tow/haul capabilities, the T-Rex featured V10 power and tandem-mounted dual rear axles. Mated to a 4-speed automatic transmission, the 8.0-liter engine produced 497 horsepower and a stout 593 lb-ft of torque. Instead of the dual rear wheels typically found on 1-ton pickups, the T-Rex sported dual single-axles; this dual rear axle arrangement, utilized instead of the dual rear wheels typically found on 1-ton “dually” pickups, was said to provide better off-road traction as well as improving maneuverability by reducing the truck’s overall width. Two transfer cases were incorporated into the T-Rex’s drivetrain. One was conventionally located aft of the transmission, the other between the rear axles. Always in “4×4” mode–both rear axles were always engaged–the T-Rex could be driven in “6×6” mode by engaging the front axle. The T-Rex was never seriously considered for production.
