The Chevrolet Colorado ZR2 only produces 2,000 units per year and it already reached its quota for this year. Bison, the ZR2 model that’s sold out, is an upgrade to an already serious off-road pickup. So does that mean that it’s nowhere to be found? Not exactly.
Thedrive.com reached out to Chevrolet in regards to the truck being sold out or not and Monte Doran, Chevrolet spokesperson, told them “the Bison is incredibly popular, and demand from both dealers and customers is exceeding supply.” That’s good for Chevrolet. Dealers have asked for far more Bison’s than they can produce.
As it stands, the Bison currently makes up about 10 percent of total Colorado sales, according to Chevrolet truck marketing director Sandor Piszar. According to official sales data, the Chevrolet Colorado tallied 134,842 US sales in 2018. Beyond the formidable ZR2 is the extreme Colorado ZR2 Bison, which tops the Colorado truck lineup in off-road capability, and price.
SO WHAT’S NEW?
Chevrolet worked with aftermarket truck outfitter AEV (American Expedition Vehicles) to take the already capable ZR2 one step further, leading to Bison. The truck outfitter also designed new front and rear steel bumpers to protect the truck from trail obstructions. The front bumper has factory accommodations for a winch and unlike the standard ZR2 bumper, the Bison’s steel bumper offers a place for a pair of standard factory fog lights.
The rear bumper features chassis mounted tubular corner pieces that wrap around the rear quarter panels to provide some extra protection. It also features two integrated recovery points for when things don’t go as planned. Lastly, a new grille with flow-through “Chevrolet” lettering replaces the traditional bowtie.
Keeping the ZR2 Bison on the road is a set of 31-inch Goodyear Wrangler Duratrac off-road tires mounted to Bison-specific 17 x 8-inch aluminum wheels. Which adds wider fender flares than the standard ZR2 to go with the new rubber and also has a 3.5-inch wider rear track. On pavement, the truck still rides smoothly in spite of its toughened, giant tires, thanks to the Multimatic DSSV dampers.
Behind the wheel, the changes don’t translate to a different experience from the regular ZR2. Those knobby rubbers still send a decent amount of road noise into the cabin and cause the truck to move a bit. The 3.6-liter naturally aspirated V-6 doesn’t have trouble holding the truck at speeds high enough. Even with those traction tires and height and the 308 horsepower and 275 ft-lb of torque.
Inside, customers will find exclusive headrest stitching and floor liners that feature the AEV logo. Outside, a snorkel, which helps the Bison ford through water, provides proper air filtration while driving on dusty trails. Other things that can be included are front and rear locking electronic differentials, Multimatic DSSV dampers, off-road rocker protection, an Autotrac transfer case, a rear axle with a 3.42 ratio and the Bison can be equipped with the optional 2.8-liter Duramax turbo diesel.
If customers are willing to do the research they will still be able to find one in dealer inventories. They will have to call daily and see if dealers have a Bison on order that has not been sold to another customer. But from a Chevrolet perspective, the vehicle is sold out.
But you’ll have to act fast since the truck is in high demand, especially the 2019 model. Chevrolet told thedrive.com that the trucks only sit on a lot for 10 days on average before being sold. That is no time at all.
