Ram Rebel TRX concept is an off-road Hellcat to fight the Ford Raptor image

Since we’re well into the third millennium, we’ve grown accustomed to vehicles doing more than 100 mph (160 km/h) on a daily basis – but how about one doing the speed while off-roading?

This is the big marketing ploy behind the new Ram Rebel TRX concept, an “extreme performance” truck that seems able to cope and even beat the all new Ford F-150 Raptor. The TRX started life as a normal Ram 1500 Rebel, but it got everything ready for rocket science. There’s a new vented hood to direct your attention to the extra cooling needed for the 575-horsepower, 6.2-liter supercharged V8 engine (it’s the Hellcat engine, with less power). There are five-inch, side-exit exhausts integrated with the side rock rails. Then the eight-speed automatic transmission has been specifically prepared for fast off-roading, with the rear axle getting an electronically locking Dynatrac Pro 60 differential. The front axle also got some love – in the form of new suspension and a wider track.

At the front the bespoke suspension control arms deliver more than 13 inches of suspension travel, versus 9 inches on a regular Ram Rebel, with adjustable coil-over shocks with external reservoirs. At the back the multilink suspension mounting points remained the same but the company increased wheel travel from 9.25 to 13 inches, also by using 2.5-inch thick bypass shocks and performance springs. Front and back stopping power comes from Baer six-piston calipers with 15-inch and 14-inch brake rotors, respectively. The Ram Rebel TRX also gets special 37-inch off-road rubber wrapped around bead-lock wheels – there are even two spare wheels and tires mounted in a special carrier in the bed, with tools and a jack stored in a lockable bed compartment.
