  6. 2027 GMC Sierra HD Pricing Confirmed For 8.3L Duramax

    General Motors prices the new 8.3L Duramax diesel engine option at $11,400 for the 2027 heavy-duty truck lineup. Despite producing segment-leading output figures of 555 horsepower and 1,230 lb-ft of torque, the upgrade costs less than competing diesel offerings from Ford and Ram.

  7. GM Launches 8.3L Mongoose Duramax for 2027 Heavy-Duty Trucks

    GM is introducing the 8.3L Mongoose Turbo-Diesel V8 for the 2027 Chevrolet Silverado HD and GMC Sierra HD. Delivering 555 horsepower, it is the most powerful diesel available in the heavy-duty pickup market. While it surpasses Ford in power, Ford retains a 2,000-pound advantage in maximum gooseneck towing capacity. The engine marks a shift in GM strategy, moving from increasing boost on its long-standing 6.6L diesel to increasing displacement to compete with Ford's Scorpion Power Stroke.

    Why it matters

    The heavy-duty diesel market is a long-term rivalry between GM, Ford, and Ram. GM previously relied on the 6.6L diesel for over twenty years. This new engine breaks a 56-year-old record previously held by GM.

    What is confirmed

    • The 8.3L Mongoose Duramax delivers 555 horsepower.
    • The 8.3L engine is the most powerful diesel available in a heavy-duty pickup.

  8. GM 8.3L Duramax Beats Ford on Power While Ford Retains Towing Edge

    General Motors claims a significant victory in the heavy-duty diesel segment with the introduction of its 8.3-litre Mongoose Duramax engine, which delivers 555 horsepower. Independent evaluation indicates that while the new GM engine beats Ford on power output, Ford maintains a higher maximum gooseneck towing capacity by 2,000 pounds. This power plant breaks a 56-year-old record previously held by GM itself, continuing a multi-brand rivalry that includes legendary platforms like the Ford 7.3L Power Stroke and various Cummins units.

    Why it matters

    Heavy-duty truck buyers continually weigh peak horsepower and torque ratings against practical hauling capabilities like gooseneck and trailer limits. Marketing claims from domestic truck brands frequently highlight specific performance advantages, making real-world load testing essential for commercial operators. Meanwhile, historical benchmarks set decades ago continue to fall as modern manufacturing pushes diesel displacement and output to new extremes.

    What is confirmed

    • GM's new Duramax engine generates 555 horsepower.
    • GM's new engine breaks a 56-year-old record previously held by GM.
    • Ford's Super Duty diesel still tows 2,000 pounds more on its max gooseneck rating.
