Chevrolet’s newest off-roader goes where other vehicles cannot
Colorado ZR2 Bison an extreme machine that drivers can use right out of the box
The Colorado ZR2 Bison is a new collaboration between Chevrolet and American Expedition Vehicles (AEV), aiming to provide an extreme off-road vehicle that you can use right out of the box.
As an off-road machine, the regular ZR2 was already pretty impressive, with front and rear electronic locking differentials, multimatic shocks and an available 2.8-litre turbodiesel engine.
AEV’s treatment has added five hot-stamped Boron steel skid plates covering the oil pan, transfer case, gas tank and front and rear locking differentials.
The toys don’t stop at stamped steel, though. You also get 31-inch Goodyear Wrangler Duratrac off-road tires wrapped around 17-inch aluminum wheels, all sitting beneath wider fender flares.
In between the wheels is a 3.5 inch-wider axle, with a 3.42 gear ratio, all lifted two inches taller than the standard Colorado.
The traditional bow-tie grill has been swapped out for a breathe through Chevrolet script, and will help the 186-horsepower, 369 pound-foot turbodiesel get all the air it needs. A six-speed automatic transmission drives power to all four wheels.
