Chevy and GMC could build heavy-duty ZR2 and AT4X off-road trucks
GM has yet to settle on a full-combustion contender for the Ford F-150 Raptor or the Ram 1500 TRX. But the company seems to be heading in that direction. The recent Chevy Silverado and GMC Sierra update included new, beefed up Silverado ZR2 and Sierra AT4X models. And, according to a report by Muscle cars and trucksGM powerful heavy trucks could also be about to get this treatment.
According to the report, the beefy Silverado HD ZR2 and Sierra HD AT4X will arrive for the 2024 model year. The package will be similar to the ZR2 and AT4 treatments on small trucks, with minimalist off-road bumpers, Multimatic DSSV shock absorberslocking front and rear differentials, skid plate and additional ground clearance.
A key change will be to the tyres. Muscle cars and trucks says GM will switch from the current 33-inch all-terrain tires on the Silverado HD Z71 and Sierra HD AT4 to 35-inch Goodyear Wrangler Territory MT tires. That would help with ground clearance and approach, breakover and departure angles and perhaps raise hopes for 35-inch factory offerings on smaller trucks.
The current range of engines should remain unchanged. The Silverado HD ZR2 and Sierra HD AT4X will offer a 6.6-liter V8 with 401 horsepower and 464 lb-ft of torque, as well as a 6.6-liter turbodiesel V8 with 445 horsepower and a whopping 910 lb-ft of torque. ft.
Heavy-duty truck buyers also like tough-looking off-road trucks, even though the trucks aren’t ideally sized for heavy-duty off-roading. And the Silverado HD ZR2 and Sierra HD AT4X should give GM two strong rivals to take on the Ford Super Duty Tremor and Ram HD Power Wagon, which made our best cars to buy in 2022 list.
