Chevrolet introduces 2019 Colorado ZR2 Bison

Chevrolet, AEV modify Colorado for extreme off-road use

Chevrolet has collaborated with off-road aftermarket manufacturer American Expedition Vehicles (AEV) to build the Colorado ZR2 Bison, Chevy’s all-new performance variant for the mid-size truck, modified for extreme off-road use.

The Bison retains the 3.6-liter V6 and eight-speed automatic gearbox of the standard ZR2, while the 2.8-liter turbo diesel and its six-speed automatic transmission, capable of 186 hp and 369 lb-ft of torque are optional. Ideal for air filtration while driving on dusty trails, a snorkel can be purchased from AEV as an additional option for the Bison.

Key undercarriage elements are protected thanks to the five skid plates covering the oil pan, fuel tank, transfer case and front and rear locking differentials – making it fitting to drive the Bison in rocky and jagged terrain. These skid plates are built from hard and durable hot-stamped Boron steel, while steel front and rear bumpers from AEV provide additional protection to the truck in tight and challenging obstacles.

“More and more enthusiasts are discovering that Colorado is ideal for off-roading, especially overland travel,” commented Sandor Piszar, director of marketing, Chevrolet Truck.

“The Colorado Z71 offers a full suite of off-road equipment, the maneuverability of a midsize truck and the driving range of a class-exclusive diesel engine. The Colorado ZR2 offers even greater off-road capability with class-exclusive front and rear locking differentials and Multimatic DSSVTM dampers. And now, Bison offers customers an even more extreme turnkey off-road truck ready to tackle your next adventure,” Piszar added.

A ‘Chevrolet’ lettering dominantly replaces the traditional Chevy bowtie on the front grill. Underneath the larger fender flairs are 31-inch Goodyear Wrangler Duratrac off-road tires, wrapping the 17 x 8-inch wheels especially fitted for the Bison. The new variant of the truck features ‘Bison’ decals on the bed sides, an ‘AEV Bison’ logo on the tailgate, and embroidered AEV logo floor liners and front head restraints

The full equipment list from the current ZR2 are also integrated in the Bison. These include, but not limited to, class-exclusive front and rear locking electronic differentials, segment-exclusive Multimatic DSSVTM dampers, off-road rocker protection, cast-iron control arms and an autotrac transfer case.

Featured  in the truck are a modified rear axle with a 3.42 ratio, front and rear tracks widened by 3.5 inches and a factory suspension lifted 2 inches over a Colorado Z71.
