When GM revealed the 2024 Chevy Silverado HD last year, it stated that Adaptive Cruise Control (ACC) will be available on the refreshed heavy duty truck. The announcement was noteworthy given that the Silverado‘s heavy-duty variant has never before offered Adaptive Cruise Control, making this an entirely new feature for the Silverado HD truck lineup.
The decision to offer ACC is particularly interesting given that General Motors previously told GM Authority that it had no plans to offer the technology on the Silverado HD. However, the then-Director of Chevrolet Truck Marketing, Bob Krapes, said GM would revisit the idea once the popularity of more luxurious Silverado HD trims increased. GM appears to feel that this time has now come.
As a reminder, Adaptive Cruise Control (RPO code KSG) enables drivers to use cruise control more effectively and comfortably. The system, which is one among GM’s suite of available active safety technology features, allows the driver to set a following gap to the next vehicle. The ACC system then brakes and accelerates the equipped vehicle to maintain the selected gap, reducing the need for driver input to maintain position in traffic. The system was updated for the Silverado HD to account for additional drag and increased braking distances when towing a trailer.
The 2024 Chevy Silverado HD will offer ACC as an option across all trim levels. On the Work Truck (WT), Custom, and LT trims, the feature will be a standalone option. The LTZ will get ACC only as part of the optional LTZ Convenience Package II (RPO code PCN). The High Country trim will make Adaptive Cruise Control available in two different options packages, the Technology Package (CWM) and the High Country Premium Package (PDM).
GM is giving the fourth-generation Chevy Silverado HD a refresh for the 2024 model year, 12 months later than originally planned. The truck’s interior has been completely redesigned for the LT and higher trim levels, with an all-new dash, digital gauge cluster and center infotainment touchscreen making their way from the Chevy Silverado 1500, which received its refresh for the 2022.5 model year. Additionally, the 2024 Chevy Silverado HD retains the column-mounted shifter because customers prefer it to a console shifter in heavy duty trucks.
On the outside, a redesigned front fascia with new headlight and grille designs is present and accounted for, while six new paint colors will be available.
The 2024 Chevy Silverado HD also sees a few key updates to its mechanicals. Trucks equipped as standard with the naturally aspirated 6.6L V8 L8T gasoline engine will now get the Allison-branded 10-speed automatic transmission, as opposed to the GM six-speed automatic transmission equipped by gasoline-powered models prior to the refresh. Meanwhile, the optional 6.6L V8 L5P turbodiesel Duramax gets an output boost to 470 horsepower and 975 pound-feet of torque.
Beyond that, the updated Silverado HD gains the GCW Alert, a gross combination weight monitoring system to warn the driver of excessive towing loads. Finally, the Custom trim level gains the optional Z71 Off-Road package, which consists of off-road suspension, Hill Descent Control (RPO code JHD), and transfer case and oil pan skid plates (NZZ).
The start of regular production (SORP) for the 2024 Chevy Silverado HD will be in February 2023. MSRP will range from $45,295 to $73,095 for 2500 HD models and from $46,495 to $75,995 for 3500 HD models, GM Authority exclusively learned.
