2027 Chevrolet Silverado HD

GM’s first in-house heavy-duty diesel sits at the heart of the 2027 Chevrolet Silverado HD. Called the Duramax 8.3L Turbo-Diesel V8, this available engine was designed, developed and manufactured by GM from a clean sheet, and its 555 hp and 1,230 lb-ft lead every heavy-duty pickup in diesel horsepower and torque. Buyers who stay with gas get an enhanced 6.6L V8, now rated at 412 hp and 472 lb-ft. Around those engines, GM has fitted a rack-and-pinion Electric Power Steering system and an electronic brake-boost system, both firsts in the heavy-duty segment. Updated drive modes and a new ZR2 Terrain Mode round out the changes. For contractors and trades moving equipment between jobsites around Saskatoon, properly equipped models will tow up to 20,000 lb (9,072 kg) conventional or 38,000 lb (17,237 kg) gooseneck. Canadian deliveries are expected to begin in late 2026, and Saskatoon Motor Products Chevrolet will be ready with details as the launch approaches.

What’s new on the 2027 Chevrolet Silverado HD?

The 2027 Chevrolet Silverado HD debuts an all-new in-house Duramax 8.3L Turbo-Diesel V8 pushing a class-leading 555 hp and 1,230 lb-ft of torque, alongside an enhanced standard 6.6L gas V8 producing 412 hp and 472 lb-ft. Both engines are paired with the Allison 10-speed transmission, complemented by segment-first Electric Power Steering, an electronic brake-boost system, and an available ZR2 Terrain Mode.

Duramax 8.3L Turbo-Diesel V8

GM’s first in-house heavy-duty diesel was designed from a clean sheet. Built with a compacted graphite iron block and fully forged internals, it delivers class-leading 555 hp and 1,230 lb-ft of torque with upgraded exhaust braking and an advanced aftertreatment layout.

Enhanced 6.6L Gas V8

The standard gas engine is upgraded to 412 hp and 472 lb-ft—class-leading standard gas torque for 2027. Enhancements include a new Turbo-Jet intake manifold, revised lubrication system, engine-mounted oil cooler, and a digital oil-level display.

Allison 10-Speed Transmission

An Allison 10-speed 10L1000 transmission serves both engines, using advanced shift logic to keep each powertrain in its optimal rev range on grades and while pulling heavy trailers.

Trailering & GCWR Ratings

Properly equipped models tow up to 20,000 lb (9,072 kg) conventional or 38,000 lb (17,237 kg) gooseneck, with select configurations achieving up to 46,500 lb (21,092 kg) GCWR for hauling heavy loads on Saskatchewan highways.

Technology

For 2027, the drive modes act as a coordinated system: each setting tells the powertrain, steering, braking and chassis how to behave. The new addition is Terrain Mode on the ZR2, a first for GM heavy-duty trucks, which allows one-pedal off-road driving in 4HI and 4LO. Ease off the accelerator and the truck brakes on its own. Trailer technology covers the rest of the list: up to 14 available camera views, among them Transparent Trailer View, Bed View and Surround Vision, plus an available in-vehicle trailering app and available trailer tire pressure and temperature monitoring.

Steering and braking form the base of the 2027 safety story. The electric steering has built-in system redundancy and gives full assist no matter the engine speed. Electronic brake boost brings support for Adaptive Cruise Control and Automatic Emergency Braking, and its diagnostics are built to flag brake fade or leaks sooner. While towing, available Trailer Side Blind Zone Alert keeps the driver aware of what is around the trailer. On gravel or loose ground, Off-Road mode permits more wheel slip and side slip, with steering and brake tuning set to reduce harsh feedback.

Exterior

Diesel-equipped trucks wear a Duramax 8.3 Turbo-Diesel badge on the hood. At the front wheels, larger rotors and new four-piston fixed calipers bring more braking capacity, and the rear brake hardware is upgraded to match. The new electric steering system does away with the hydraulic pump and hoses, and its components use corrosion- and impact-resistant hardware designed to stand up to road debris and severe-duty use on construction sites.

Two variants stand apart in the 2027 range. Dually trucks handle the heaviest trailers, and GM rates every diesel dually for an available 30,000 lb (13,608 kg) or more. The ZR2 heads the other way, built for trails and loose surfaces. Underneath all versions, GM revised the chassis and suspension and tuned them alongside the steering and brakes so the truck stays composed when towing close to its ratings. Available cameras give up to 14 views, with Bed View and Surround Vision covering the box and the area around the truck. Chevrolet builds the Silverado HD at Oshawa Assembly as well as Flint Assembly.

Interior

The 2027 cabin updates centre on control. Steering effort now comes from an electric system with roughly 30% more output than the outgoing hydraulic gear, so parking a heavy-duty truck in a busy downtown Saskatoon lot or turning into a tight jobsite takes less work at low speed. The wheel offers improved on-centre feel and reduced kickback. Brake pedal travel is shorter, the pedal sits in a new spot and its feel is more linear and predictable.

Hitching up gets easier from the driver’s seat. The available in-vehicle trailering app guides trailer setup, while camera views such as Transparent Trailer View help with reversing toward a coupler or checking the lane beside the trailer. The cab also benefits from quieter hardware. Taking out the hydraulic steering pump removes a source of traditional steering noise, and in diesel trucks, crankshaft isolation hardware, an integrated intake and an advanced combustion system cut down the noise and vibration that reach the occupants.

Versions

The Silverado HD offers distinct configurations designed to match every commercial and off-road demand.

Buyers who head off pavement will look at the ZR2, the off-road Silverado HD and the one that brings Terrain Mode. Those who tow at the top of the scale have dually configurations, with each diesel dually rated for an available 30,000 lb (13,608 kg) or more. Every version draws from the same two engines: the standard enhanced 6.6L gas V8 at 412 hp and 472 lb-ft, or the available Duramax 8.3L Turbo-Diesel V8 at 555 hp and 1,230 lb-ft.
