Key Features of the 2026 Chevrolet Silverado 2500 HD
6.6L Duramax Turbo-Diesel V-8
The available 6.6-liter Duramax turbo-diesel V-8 is the heart of the Silverado HD’s maximum capability. Rated at 470 horsepower and 975 lb-ft of torque, the Duramax pairs immediate low-end thrust with sustained pulling power on grades and in headwinds—precisely where heavy trailers test lesser trucks. The diesel’s broad torque plateau combines with the Allison 10-speed’s closely spaced ratios to keep the engine in its sweet spot, limiting downshifts and enabling smooth, confident acceleration with a load. It is this synergy that underpins the truck’s up-to-36,000-pound tow rating when properly configured. From a quiet, refined idle to sustained, high-load climbs, the Duramax is tuned for durability and control, making it the go-to for frequent tow and haul duty.
6.6L Gas V-8
Standard power comes from a robust 6.6-liter gas V-8 with 401 horsepower and 464 lb-ft of torque. This engine provides strong, predictable response around town and on the highway, with linear power delivery that suits daily driving, plowing, jobsite hauling, and weekend trailer duty. The pairing with the Allison 10-speed automatic elevates the gas engine’s versatility, keeping revs optimized for response or efficiency depending on load and terrain. Properly equipped, gas models can tow up to 17,400 pounds—ample for boats, campers, or jobsite equipment. For owners who split time between commuting and moderate towing, the gas V-8’s straightforward ownership and ample capability present an appealing balance.
Allison 10-Speed Automatic
Both engines are mated to an Allison 10-speed automatic transmission that is engineered for heavy-duty workloads. The wide ratio spread and intelligent shift logic help the truck step off smoothly with a load, hold gears confidently on climbs, and downshift proactively for engine braking on descents. The transmission’s calibration works hand-in-glove with trailer profiles and driver-assistance features, enhancing stability while minimizing gear hunting. Whether you opt for rear-wheel drive or four-wheel drive—and single or dual rear wheels—the Allison 10-speed provides consistent, predictable behavior in challenging conditions, which is exactly what you want when towing long distances or navigating tight sites.
14-Camera Trailering System with Transparent Trailer View
Trailering confidence starts with information you can see. The Silverado HD offers up to 14 available camera views, including a transparent trailer view that virtually lets you see “through” a compatible trailer to monitor surrounding traffic and obstacles. Additional perspectives—hitch, bed, rear side, rear top-down, and more—simplify everything from lining up a gooseneck to backing into a narrow driveway. On-screen trailer profiles let you track maintenance and customize settings; you can even access certain functions via a smartphone app. Paired with available Adaptive Cruise Control tuned for trailering and other assists like Blind-Spot monitoring and Rear Cross Traffic alert, the camera system helps reduce stress at low speeds and on the highway alike.
13.4-Inch Infotainment with Google Built-In, Apple CarPlay, and Android Auto
The cabin is a command center built around clarity and control. On LT, LTZ, Trail Boss, High Country, and ZR2 models, a standard 13.4-inch touchscreen anchors an interface with Google built-in for seamless voice assistance, navigation, and app access. Apple CarPlay and Android Auto are standard, and an available integrated wireless charging pad keeps devices ready. Physical knobs for volume and tuning, along with hard keys for frequent functions, let you adjust settings with gloves on or while bouncing over rough surfaces. Add in available amenities such as a head-up display, heated and ventilated front seats, heated rear seats, and a heated steering wheel, and the Silverado HD’s interior is prepared for long stints behind the wheel—summer or winter.
