GMC Sierra spied with ZR2-style off-road modifications

A few months ago, the 2022 Chevy Silverado ZR2 was revealed with a bunch of off-road goodies to help it achieve a little more parity with trucks like the Ford F-150 Raptor and Ram 1500 TRX. But GM has another full-size truck, the GMC Sierra, and it would seem silly to us if the company didn't share those parts. Based on these spy photos, it seems GM agrees. Though thoroughly camouflaged, we can tell this truck is a GMC Sierra thanks to the sheetmetal on the doors and the distinct shape of the wheel arches. Under the wrappings, we can see that this Sierra features a very different front bumper to the current king of Sierra off-road models, the AT4X. The bottom edge is much higher for better clearance, particularly on the sides in front of the wheels. This is the same type of change applied to the Silverado ZR2's front end. It does appear to be missing the ZR2's skid plate, though we suspect that's a temporarily missing component on this prototype. One other off-road upgrade this Sierra features is a pair of rock rails to protect the rocker panels on the cab. What we can't see are the shocks installed on this truck. If this is a GMC version of the ZR2, it should have the spool-valve shocks from Multimatic. They're some of our favorite suspension components on any vehicle. Other components it should have are locking front and rear differentials, 33-inch tires and a standard 6.2-liter V8. Since the Silverado ZR2 is already revealed and ready for production, we would expect to see the GMC version soon. A good bet would be for a reveal in time for the 2023 model year. As for a name, it's hard to say, since we've already had AT4 and AT4X. It could be named something completely separate from the AT4 line. Related Video: This content is hosted by a third party.

2020 Chevy Silverado, GMC Sierra recalled due to faulty brake component

General Motors is recalling 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups to fix a defect in the trucks' brake system. Certain Silverado and Sierra pickups were produced with brake-caliper bolts that were not heat-treated. Without heat-treating, the bolts are weaker than they should be, and there is a risk that they could fail, which would affect the trucks' braking performance, possibly leading to a crash. In total, 20,352 vehicles are affected. Owners of affected trucks will be contacted by GM. Dealers will inspect the bolts and replace those that are defective. Related Video:      

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.
