Our spy photographer reports:

We now have our first visual evidence that GM has begun testing facelifts for its HD pickups, in the guise of this 2023 GMC Sierra HD prototype.

Just as we’ve seen in the mid-cycle updates for the Sierra 1500 trucks, everything in front of the A-pillars and aft of the C-pillars is fully camouflaged. Placeholder headlights suggest meaningful changes up front, including an updated grille design (covered here in both mesh and graphic camouflage).

The prototype caught here looks to be a somewhat base Sierra HD trim-level, judging from the silver-painted 18-inch steel wheels. The truck appears to be augmented with something akin to today’s X31 Off-Road Package, judging from the aggressive Hankook Dynapro MT2, hints of underbody skid plates, and the Rancho shocks visible in the rear suspension.

The interior of this Sierra HD mid-cycle facelift had a fully-camouflaged interior, suggesting that GM will be employing similar interior improvements to its HD models that are currently being developed for its half-ton trucks. Expect GMC to offer an upgraded infotainment screen in the HD, as the F-150’s 12-inch screen has been made available to the Ford Super Duty pickups as part of its higher trim levels.

We’ll be on the lookout for more examples of GM’s refreshed HD prototypes in different trim levels, as testing is sure to be ramping up over the next few months.
