The 2027 Chevrolet Silverado HD adds an all-new 8.3L Duramax Turbo-Diesel V8 producing 555 hp and 1,230 lb-ft of torque. That is a significant leap over the outgoing HD lineup, paired with first-in-class electric power steering and new eBoost braking. This page covers every new feature, all six trims, and information about upcoming 2027 Silverado HD availability at ASA Auto Plaza in Austin, MN.

What's New for 2027

The headline change for 2027 is the all-new Duramax 8.3L Turbo-Diesel V8. At 555 hp and 1,230 lb-ft of torque, it delivers best-in-class figures in both categories, and it pairs with an Allison 10-speed automatic transmission that includes diesel exhaust braking and grade-braking strategies to reduce brake stress on long descents.

The gas engine is not carried over unchanged either. Chevrolet revised the 6.6L V8 to extract 412 hp and 472 lb-ft of torque, and added an oil level sensor with a Driver Information Center readout as a standard feature on that configuration.

Two additional firsts arrive for the heavy-duty segment:

• Electric power steering is new for the class entirely. An electrically assisted rack-and-pinion system replaces the hydraulic setup, delivering quieter operation, reduced steering kickback off-road, and more precise feedback under a load. On the ZR2, it directly unlocks Terrain Mode.
• eBoost electronic brake boost is also a segment first. The system delivers smoother, faster brake response with improved consistency, which matters most when braking repeatedly under a trailer load or descending a steep grade.

The camera system grows to up to 14 available views covering hitching, lane changes, reversing, and trailer monitoring. Inside, a 13.4-inch touchscreen and a 12.3-inch Driver Information Center anchor the cabin, with Google Gemini AI assistant and Google built-in available on equipped trims.

OnStar Basics is now standard for eight years, covering remote commands, Automatic Crash Response, built-in voice assistance, and real-time navigation.

Trail Boss is now available on the Custom trim for the first time.

Trim Lineup

The 2027 Silverado HD is offered in six trims: WT, Custom, LT, LTZ, ZR2, and High Country.

WT

WT is the foundation of the lineup. It is built for work-site duty with a focus on capability over comfort, making it the most straightforward choice for fleet and commercial buyers in the Austin, MN area.

Custom

Custom adds styling upgrades and broader feature content over the WT. It is also the first trim to offer the Trail Boss package in 2027, which is a notable addition for buyers who want off-road readiness at an accessible trim level.

LT

LT brings greater versatility through added comfort and technology features, positioning it as a strong middle-ground option for buyers who tow regularly but also use the truck as a daily driver.

LTZ

LTZ steps up with a premium interior and styling package alongside the full capability suite. It targets buyers who want the power of the HD platform without giving up interior refinement.

ZR2

ZR2 is the off-road-focused trim and carries the most specialized hardware in the lineup. It adds Multimatic DSSV dampers, a rear e-locker, 35-inch MT tires, aluminum skid plates, and Terrain Mode, which is unlocked by the truck's new electric power steering and eBoost system. A 1.5-inch factory lift is installed from the factory.

High Country

High Country occupies the top of the range with the most premium interior treatment, including leather-appointed seating, wood-grain trim accents, and the full suite of technology features.

Performance and Powertrain

Buyers choose between two engines for 2027.

The available all-new Duramax 8.3L Turbo-Diesel V8 is the stronger option, rated at 555 hp and 1,230 lb-ft of torque. Maximum available towing with this engine reaches 38,000 lbs, and maximum available payload reaches 6,170 lbs. It connects to an Allison 10-speed automatic with diesel exhaust braking built in. SAE towing and payload methodology

The enhanced 6.6L gas V8 produces 412 hp and 472 lb-ft of torque. In this configuration, max available towing reaches 19,000 lbs and max available payload reaches 6,990 lbs. It uses a 10-speed automatic transmission and now includes an oil level sensor with DIC readout as a standard feature.

Both engines are new or revised for 2027, and Chevrolet describes both as delivering more horsepower and torque than any previous Silverado HD generation.

The Allison-backed diesel also benefits from Tow/Haul Mode, which increases steering damping for better trailer control, and from grade-braking logic that reduces wear on the friction brakes during long downhill runs.

Interior, Comfort and Cargo

The 2027 Silverado HD cabin is anchored by a 13.4-inch touchscreen and a 12.3-inch Driver Information Center. The High Country trim presents the most refined interior in the lineup, with two-tone leather upholstery, perforated seat surfaces, contrasting stitching, and a head-up display.

Rear seat space in crew cab configurations provides generous legroom with rear climate vents, and the Multi-Flex Tailgate carries forward to extend cargo flexibility at the bed. The Durabed is a steel cargo box with reinforced structure designed to resist denting under heavy use.

Technology and Infotainment

The 13.4-inch touchscreen supports Google built-in as an available feature, giving drivers access to Google Maps, Google Play apps, and voice commands without requiring a phone. Google Gemini is the available AI assistant, handling natural language requests for navigation, calls, messages, and truck settings.

The camera system is one of the most capable in the segment, with up to 14 available views that cover hitching assist, trailer side blind zone monitoring, lane change views, and reversing. A trailer camera view is displayed directly on the touchscreen.

Adaptive Cruise Control is standard. OnStar Basics is standard for eight years and includes Automatic Crash Response, remote commands, built-in voice assistance, and access to audio streaming apps.

The oil level sensor with DIC readout is now standard on the 6.6L gas V8, reducing the need for manual dipstick checks between service intervals.

Safety and Driver Assistance

Standard safety systems on the 2027 Silverado HD include Forward Collision Alert, Automatic Emergency Braking, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Following Distance Indicator, IntelliBeam automatic high beam assist, and Adaptive Cruise Control.

Two systems are segment firsts. The eBoost electronic brake boost delivers more predictable, smoother stopping power under load. Electric power steering reduces steering kickback, which improves driver confidence on uneven terrain and during repeated maneuvering at a job site.

On the ZR2, Terrain Mode is available and is unlocked specifically through the combination of electric power steering and eBoost, making it unique to the 2027 generation. The diesel configuration adds exhaust braking through the Allison transmission, which reduces reliance on friction brakes when descending grades while towing.

Who It's For Compared to the Prior Generation

Buyers upgrading from a previous-generation Silverado HD will notice the most immediate differences in steering feel and braking response. The switch from hydraulic to electric power steering changes how the truck responds in tight quarters and on switchbacks, with noticeably reduced kickback on rough surfaces.

For anyone who tows regularly on steep or long grades, the combination of eBoost braking and the Allison diesel exhaust brake represents a real operational improvement over the outgoing system, not just a specification upgrade.

The ZR2 is the right choice for buyers who push the truck on unpaved trails and need factory off-road hardware without aftermarket modifications. The Trail Boss on Custom now gives off-road capability to buyers working with a tighter budget who previously had to step up to a higher trim.

For commercial and fleet buyers near Austin, the WT and Custom trims retain the focused capability that makes the Silverado HD a standard on job sites across southern Minnesota.

The 2027 Silverado HD is expected to be released at the end of November 2026. Until then, shoppers can contact ASA Auto Plaza for availability updates and information about the upcoming model. Preproduction models have been shown and actual production models may vary.
