Ford helped to popularize the off-road truck craze with the F-150 Raptor and it appears General Motors could be working on a competitor of sorts.
According to Muscle Cars and Trucks, Chevrolet is developing a hardcore Silverado which could be called the ZRX. It will reportedly be more extreme than the Silverado Trail Boss and borrow heavily from the Colorado ZR2 playback.
While nothing is official, the publication says the pickup will be outfitted with an off-road focused suspension that features Multimatic DSSV dampers. The truck is also rumored to have front and rear locking differentials as well as improved approach and departure angles.
It remains unclear if the latter improvements will come from the suspension alone, but it’s possible the truck could have a modified front bumper as the Colorado ZR2’s has “tapered ends to increase tire clearance when approaching obstacles.” The ZR2 also features a 2 inch (51 mm) lift kit, underbody protection and cast iron control arms for improved strength. Other highlights include a unique grille, a revised hood and exclusive wheels wrapped in 31-inch Goodyear Wrangler Duratrac off-road tires. That’s on top of the aforementioned DSSV dampers and electronic locking differentials.
Unfortunately, the truck could also mimic the Colorado ZR2 in a less desirable way – keeping stock powertrains. That would make the Silverado ZRX a bit of an oddball as the F-150 Raptor has a twin-turbo 3.5-liter V6 that develops 450 hp (336 kW / 456 PS) and 510 lb-ft (691 Nm) of torque. Likewise, the upcoming Ram 1500 Rebel TRX is slated to have a supercharged 6.2-liter V8 engine that produces around 707 hp (527 kW / 717 PS) and 645 lb-ft (875 Nm) of torque.
The Silverado ZRX, on the other hand, is expected to feature carryover engines including a 6.2-liter V8 that produces 420 hp (313 kW / 426 PS) and 460 lb-ft (623 Nm) of torque. That’s significantly less than the competition, but the truck could also be offered with a 3.0-liter Duramax turbodiesel engine that develops 277 hp (207 kW / 281 PS) and 460 lb-ft (623 Nm) of torque.
If everything pans out, the off-road focused truck could be launched in time for the 2022 model year.
