Key Features of the 2026 Chevrolet Silverado 2500 HD

Duramax 6.6L Turbo-Diesel V8

For demanding hauls, the available Duramax 6.6L Turbo-Diesel V8 delivers 470 horsepower and 975 lb-ft of torque. Its broad torque curve and diesel braking characteristics help steady heavy trailers over grades and during throttle transitions, while the engine’s durability has been proven across work fleets nationwide. Pairing this diesel with the Allison 10-speed automatic optimizes power delivery for smooth launches and low-RPM cruising. Rated to pull up to 36,000 pounds when properly equipped, the Duramax powertrain gives you the headroom to take on bigger trailers and more frequent towing with the kind of calm control that reduces driver fatigue.

6.6L Gas V8

The standard 6.6L gas V8—rated at 401 horsepower and 464 lb-ft of torque—provides stout, linear power for mixed-duty use. It is a smart choice for owners who alternate between hauling materials, commuting, and occasional towing. Its pairing with the Allison 10-speed automatic keeps the engine in the sweet spot of its powerband, allowing confident acceleration and steady highway speeds with a trailer in tow. If you value straightforward maintenance and a responsive feel, this gas V8 is an excellent foundation for a capable, well-balanced Silverado 2500 HD.

Allison 10-speed Automatic Transmission

Both engines are matched to the Allison 10-speed automatic transmission, chosen for its robust build and smart calibration. With closely spaced ratios, the Allison helps keep RPM where the engine is most efficient and responsive, whether you are inching across a job site or overtaking on the highway. It also contributes to steady downhill control and smoother towing dynamics. In daily use, drivers appreciate the transmission’s quick, decisive shifts and its ability to adapt to varying loads, making the truck feel composed with or without a trailer.

14-Camera Trailer System with Transparent Trailer View

Available up to 14 camera views expand your awareness around the truck and trailer. Transparent Trailer View is a standout, digitally stitching camera feeds to help you virtually “see through” the trailer, making it easier to merge, change lanes, and back into tight spaces. Additional views—such as bed, hitch, and rear side angles—simplify solo hookups and reduce guesswork in crowded lots. For owners who regularly tow different trailers, the ability to store trailer profiles, monitor maintenance, and integrate controls through the in-vehicle interface and compatible smartphone apps adds confidence and convenience to every trip.

Google built-in with 13.4-inch Diagonal Color Touchscreen

On LT, LTZ, Trail Boss, High Country, and ZR2 models, a 13.4-inch diagonal color touchscreen comes standard and runs Google built-in, with Apple CarPlay and Android Auto also supported. The large display is complemented by physical knobs and buttons for key functions, striking a balance between modern graphics and glove-friendly usability. You can set up different trailer profiles, access navigation, manage communications, and adjust vehicle systems with voice commands, all designed to reduce distractions. Wireless smartphone charging on these trims keeps your device topped up while the cabin’s abundant storage—center console bin, under-seat storage on select models, and more—keeps essentials tidy and within reach.
