The Chevy Silverado HD will receive a major model refresh for the 2024 model year, introducing a wealth of updates and changes for the heavy-duty pickup nameplate. Now, GM Authority has caught this 2024 Silverado 3500HD prototype testing on public roads, giving us an early look at what’s in store.
This particular 2024 Chevy Silverado 3500HD prototype is done up in the Crew Cab / Long Bed body style, with Dual Rear Wheels, otherwise known as a Dually or DRW. The truck is covered in heavy camouflage, obscuring the revised styling up front and in the rear. Nevertheless, there are a few details we can pick out, such as the broad horizontal slats used for the front grille, as well as revisions for the forward-facing lighting.
Moving to the sides, we see black door handles and black window trim, thus suggesting that this particular 2024 Silverado 3500HD prototype is the likely the base Work Truck trim level. The truck is also obviously towing a trailer via a hitch, with what looks to be a weight plate on the trailer itself.
The rear end is also obscured, covering up what is expected to be a rear styling update. The camo covers were added to the rear fenders, the tailgate, and the taillights.
In addition to revised exterior styling, the refreshed 2024 Silverado HD will also feature a completely revamped interior that will take after the refreshed 2022 Silverado 1500 light duty pickup.
What’s more, the 2024 Silverado HD should deliver a relatively solid powertrain update. As GM Authority covered previously, refreshed 2024 Silverado HD and 2024 Sierra HD models equipped with the Duramax diesel engine are rumored to dole out nearly 1,100 pound-feet of torque and more than 500 horsepower. For those keeping score at home, that’s a major boost over the current tune for the 6.6L V8 L5P turbodiesel Duramax, which is rated at 910 pound-feet of torque and 445 horsepower.
Finally, the refreshed 2024 Silverado HD will introduce a new Silverado HD ZR2 off-roader model for vehicles equipped with a single-rear wheel layout. As GM Authority was the first to report, the new Silverado HD ZR2 is expected to be equipped with front and rear locking diffs and new specialty dampers, plus aggressive 35-inch Goodyear Wrangler Territory MT tires.
As a reminder, the Silverado HD was originally slated for a refresh with the 2023 model year, but due to complications stemming from the COVID-19 pandemic and ongoing microchip shortage, the refresh was delayed a year.
