How much torque does a 2024 Duramax have?

In 2024, Duramax engines provide two distinct torque profiles: up to 495 lb-ft in the light-duty 3.0L inline-six turbodiesel and up to 910 lb-ft in the heavy-duty 6.6L V8 turbodiesel.

Two Duramax Engines, Two Torque Profiles

The 2024 Duramax lineup spans a light-duty option for everyday driving and towing, and a heavy-duty option built for maximum hauling. Each engine delivers its peak torque in different contexts to serve its intended use.

• Light-Duty Duramax Turbo Diesel (3.0L inline-six) — up to 495 lb-ft of torque. This engine powers the Silverado 1500 and Sierra 1500, among other light-duty applications, and is paired with a 10-speed automatic transmission in these pickups.


• Heavy-Duty Duramax Turbo Diesel (6.6L V8) — up to 910 lb-ft of torque. This engine is used in the Silverado 2500HD/Sierra 2500HD and Silverado 3500HD/Sierra 3500HD, typically paired with an Allison 10-speed automatic and a broader towing feature set.

Across the Duramax family, the torque figures reflect the contrasting roles: the light-duty engine emphasizes strong mid-range pull for daily driving and moderate towing, while the heavy-duty engine is tuned for maximum pulling power and heavy-haul capability.

Where the Torque Shows Up in 2024 Models

Understanding how these torque numbers translate into real-world performance helps buyers match the engine to their needs, whether that’s daily commuting, weekend towing, or long-haul payloads. The published torque figures are maximums and can vary with drivetrain configurations, axle ratios, exhaust setups, emissions calibrations, and market-specific tuning.

Light-Duty Duramax: Everyday Towing and Acceleration

The 3.0L Duramax delivers up to 495 lb-ft of torque to provide confident acceleration and mid-range pulling power in lighter-duty applications. This makes it well-suited for typical trailering tasks, highway merging, and steady highway climbing, while maintaining reasonable fuel efficiency and refinement for daily driving.

Note: Torque is optimized for mid-range responsiveness and smooth operation with the light-duty transmission pairing; exact numbers can vary by model year and market.

Heavy-Duty Duramax: Maximum Hauling and Towing

The 6.6L Duramax produces up to 910 lb-ft of torque, designed to move heavy trailers, heavy payloads, and challenging grades with authority. In HD trucks, torque is available at low engine speeds to improve lugging resistance, control on grades, and stability when towing at or near the vehicle’s maximum ratings.

Note: As with the lighter engine, real-world torque depends on configuration, including axle ratio, gearing, and any competition or market-specific calibrations.

Notes on Variations and Verification

GM publishes torque figures for each model year and configuration, but exact numbers can vary by market, trim, and optional equipment. Always verify the specific window sticker or official GM specifications for your exact vehicle to confirm the torque rating you’ll experience in use.

Summary

The 2024 Duramax lineup offers a clear split in torque across two engines: 495 lb-ft for the light-duty 3.0L inline-six and 910 lb-ft for the heavy-duty 6.6L V8. This range supports a broad spectrum of use cases—from everyday driving and moderate towing to maximum-haul tasks. For precise figures on a given vehicle, consult the official specifications for that exact model and configuration.

How much horsepower does a 2024 Chevy Silverado 2500 6.6 Duramax have?

470 horsepower
The optional Duramax diesel 6.6-liter V-8 carries over from the previous generation. It continues to make 470 horsepower and 975 pound-feet of torque.

Is a 6.7 Cummins better than a 6.6 Duramax?

The Cummins 6.7L is known for its high torque, ideal for heavy towing, while the Duramax 6.6L generally offers more horsepower for quicker acceleration. The choice between them depends on your priorities: the Cummins excels in raw pulling power, whereas the Duramax is often favored for its horsepower and smoother driving experience due to its V8 design and independent front suspension, notes CarBuzz and SlashGear. 
Performance and specs

• Cummins 6.7L I6: Typically offers higher torque, with some versions providing up to 1,0751 comma 0751,075 lb-ft, making it a top choice for maximum pulling power. 
• Duramax 6.6L V8: Usually has a higher horsepower rating, with up to 470470470 hp, which can result in quicker acceleration. 
• Engine design: The Cummins uses an inline-six design, while the Duramax is a V8. 

Driving experience

• Duramax: Often described as having a smoother, quieter ride, partly due to its independent front suspension setup. The power delivery is smooth and consistent. 
• Cummins: Known for its strong low-end torque for initial acceleration, but can sometimes feel more "crude" or have a harsher ride compared to the Duramax. 

Other factors

• Price: The Duramax engine is sometimes associated with a lower initial truck cost. 
• Fuel efficiency: Fuel economy is comparable between the two, though it varies based on driving conditions and load. 
• Reliability: Both are generally reliable, but some older Duramax engines have faced issues with their fuel pumps, while the Cummins has faced some transmission concerns. 

Which engine is right for you?

• Choose the 6.7L Cummins if your priority is maximum towing and payload capacity and the highest possible pulling power. 
• Choose the 6.6L Duramax if you prefer higher horsepower for quicker acceleration and a smoother, quieter, and more car-like driving experience. 

How much horsepower and torque does the 2024 Duramax have?

The truck's L5P Duramax diesel engine received a substantial bump in power and torque thanks to a stout list of upgrades, including a new turbocharger, improved piston design, enhancements to the high-pressure fuel system, a new calibration, and more. The result is 470 horsepower and a massive 975 lb-ft of torque.

How much torque does a 2025 6.6 Duramax have?

The 2025 6.6L Duramax turbo-diesel engine produces 975 lb-ft of torque at 1600 rpm. This engine is available on heavy-duty Chevrolet Silverado and GMC Sierra trucks and is paired with an Allison 10-speed automatic transmission.
