Dodge Ram Rebel TRX Concept Truck Explained – Video

Rebel TRX is a 100-mph off-road machine with 575 horsepower – the most powerful half-ton truck the company has ever built. Ripping over pavement at speeds greater than 100 mph is an experience, but the Ram Rebel TRX concept hits triple digits in an off-road environment with the help of a supercharged 6.2-liter HEMI® V-8.

The rapidly beating heart of the Ram Rebel TRX concept is a powertrain marvel. A 6.2-liter supercharged HEMI with 575 horsepower, the most powerful Ram 1500 the company has ever built, lays the groundwork of expectation.

Mated to the TorqueFlite 8HP70 eight-speed automatic transmission, new calibrations were used for the engine, transmission and drivetrain to optimize the expected high-speed off-road driving cycle.

 

 

The Ram Rebel TRX concept uses Ram’s 4×4 Performance Control System with a BorgWarner 44-45 transfer case. The system employs different modes of operation: Normal, Wet/Snow, Off-road and Baja.

The Ram Rebel TRX concept uses a standard Ram 1500 front axle with an open differential and custom CV half-shafts to handle the wider track dimension. The spindles are moved forward to make room within the fender wells for the aggressive 37-inch tires.

In the rear, a Dynatrac Pro 60 axle spools power through an electric, selectable locker to 35-spline, 1.5-inch axle shafts. The locker is available in all modes and commits both rear wheels to traction at the same speed, spreads the torque load and maximizes the tractive effort (power put to the ground) in full-throttle maneuvers.
