Alongside pricing for the 2027 Chevrolet Silverado HD, General Motors has also released partial pricing for its fancier cousin, the 2027 GMC Sierra HD. Like the Silverado, the Sierra comes with an upgraded gas engine and an all-new turbodiesel with best-in-class horsepower and torque. The GMC also brings with it added luxury, especially if buyers opt for the Denali and Denali Ultimate trims. However, when equipped with the new diesel, the most expensive Sierra HD is now a six-figure pickup. Here's a look at the latest pricing.Related: 2027 Chevy Silverado HD Prices Rise Across The Lineup2027 GMC Sierra HD Pricing2027 GMC Sierra HDGMCFor now, GMC has only released pricing for the 2027 Sierra 2500 HD Crew Cabs with four-wheel drive.

It starts with the upgraded 6.6L V8, which now delivers 412 horsepower and a class-leading 472 lb-ft of torque. The 8.3L V8 Duramax turbodiesel is a monster, with 555 hp and 1,230 lb-ft; both figures are better than Ford's high-output Power Stroke diesel. With this engine, the Sierra HD can tow up to 38,000 lbs. To further improve towing confidence, there are larger 14.6-inch diameter front brake rotors and a new calibration for the truck's Tow/Haul modes.GM 8.3L Duramax TurbodieselGMCA segment-first addition is the rack-and-pinion electric power steering design. It improves control in on- and off-road conditions, while operating more quietly under the hood. The AT4X gains improved DSSV dampers and a trim-exclusive Terrain Mode; it's the most capable off-road trim in the range.GMC hasn't made any major design or interior changes, so buyers can expect similar 13.4-inch touchscreen displays. The Denali Ultimate is one of the industry's best luxury pickups. It comes with wood trim, power front seats with massage, opulent leather upholstery, a Bose premium sound system, and illuminated power assist steps.The 2027 GMC Sierra HD will be available late in 2026.Related: Chevy and GMC HD Trucks Get the Punchier V8 Engines They DeserveWhat It Means2027 GMC Sierra HDGMCOver $100,000 for a pickup truck will sound excessive to the average sedan or SUV driver, but the GMC Sierra has always pushed deeper into luxury territory than the related Silverado. Equipped with the diesel engine and in Denali Ultimate guise, it's a vehicle that doesn't force buyers to choose between comfort and capability—this truck delivers both.The 2027 Sierra HD is not a full redesign, unlike the 2027 Sierra 1500. However, we expect GMC to fully update the HD models a year or so from now, when they're likely to adopt the design language and tech of the 1500.Related: GM's 2027 Truck Engine Lineup Has More V8s and a Monster New Diesel
