The 2024 Chevy Silverado 2500HD and 3500HD get a facelift, and most models receive a ritzier interior with bigger screens.
Gas-fed models now have a 10-speed automatic transmission, and diesel models make 470 horses (up 25) and 975 pound-feet of torque (up 65).
The '24 Silverado HD twins will go into production in the first half of 2023, with the first-ever ZR2 version also eventually joining the lineup.
Chevy's big pickup trucks—the Silverado 2500HD and 3500HD—are getting refreshed for the 2024 model year. Along with new facial features, most trim levels benefit from a flashier interior design that first debuted on the half-ton Silverado about a year ago. The improvements to the 2024 Chevy Silverado HD trucks are more than skin deep, though.
New Transmission, Mightier Diesel
Sure, the facelift and redesigned cabin help Chevy's heavy-duty pickups stay looking fresh, but the bottom line is that the Silverado 2500HD and 3500HD are built for work duty. That's where their updated powertrains come into play. The standard gas-fed 6.6-liter V-8 is unchanged, meaning it makes the same 401 horsepower and 464 pound-feet of torque as its predecessor. However, it now pairs with an Allison 10-speed automatic transmission instead of a six-speed automatic. Chevy says the gasser's new gearbox helps the engine make better use of its peak power. For 2024, gas-burning Silverado HDs also have a higher Gross Combined Weight Rating (GCWR), which rises from 24,000 to 26,000 pounds.
The optional Duramax diesel 6.6-liter V-8 continues with the same Allison 10-speed automatic, but its output gets a significant uptick. It now makes 470 horsepower (up from 445) and 975 pound-feet of torque (up from 910). Chevy says the increases result from updates to the control architecture, combustion system, and turbocharger, which are also said to help provide up to 25 percent more low-end torque and improve efficiency. However, we don't know how the updates will affect fuel economy since the trucks are exempt from EPA testing and the company isn't currently sharing estimates. What we do know is that the 2024 Silverado 2500HD and 3500HD still have max tow ratings of 22,500 and 36,000 pounds, respectively.
Fresh Face, Flashier Interior
For 2024, the supersize Silverados all wear new mugs, from the base-level Work Truck to the top-of-the-line High Country. Along with the newly designed grille and C-shaped LED lighting elements, the LTZ and High Country trim levels feature new dual-projector headlights with animated sequences for when the driver approaches or walks away from the trucks. Chevy also supplies the '24 Silverado HD with new wheel options, including chrome 20-inch wheels for the LTZ as well as polished 18-inchers and all-terrain tires for the dual-rear-axle 3500HD. Plus, a set of 20-inch off-road tires can now be had with certain packages. The Midnight Edition, a blacked-out appearance package, is also now available on the High Country for the first time.
Inside, heavy-duty Silverados adopt a new dashboard design with prominent digital displays. While the updated layout and tech features aren't offered on the Work Truck or Custom trim levels, they're standard on the LT model and up. The setup includes a configurable 12.3-inch gauge cluster and a 13.4-inch touchscreen with Google-based software and apps. The updated interior also brings a revised center console with a wireless charger and more space for cupholders. The fanciest Silverado models have real leather-wrapped surfaces and genuine wood accents. Exclusively on the High Country, there's a new Nightshift Blue interior option with all the top-notch materials.
The Silverado HD trucks also benefit from better driver assists. The list includes adaptive cruise control that works while pulling a trailer, and the blind-spot monitor now has an extended range while trailering. Plus, there's a new alert that lets users know if they exceed the truck's GCWR, and the available camera view that uses technology to essentially make a trailer transparent has been enhanced to work with fifth-wheel and gooseneck setups.
ZR2, Coming to a Silverado HD Near You
The 2024 Chevy Silverado 2500HD and 3500HD will go on sale in the first half of 2023. The company says it'll share pricing closer to their on-sale date. Chevy also today announced that the heavy-duty Silverado will be getting a version of the off-road-ready ZR2 model for the first time ever, but it'll launch sometime after the regular trucks.
