2027 vs 2026 Silverado HD: More Diesel Power Arrives

Its new available 8.3L Duramax Turbo Diesel V8 produces 555 horsepower and 1,230 lb ft of torque, helping raise maximum available towing to 38,000 pounds. The 2026 Silverado HD uses a proven 6.6L Duramax with 470 horsepower, 975 lb ft of torque and up to 36,000 pounds of towing capability. The 2027 also introduces electric power steering and eBoost braking.
