Both are paired with an Allison 10-speed automatic transmission for smooth power delivery. Available with rear-wheel drive (RWD) or four-wheel drive (4WD), these engines cater to varied driving conditions.
Let’s dive into each engine to understand their strengths and applications.
6.6L V8 Gas Engine: Reliable Power for Everyday Tasks
The standard engine in the 2025 Chevy Silverado 2500 Engine Options is the 6.6-liter V8 gas engine.
It delivers 401 horsepower at 5,200 RPM and 464 pound-feet of torque at 4,000 RPM.
This powertrain suits drivers needing a dependable workhorse for daily tasks without diesel’s higher cost.
Ideal for moderate towing, it offers a maximum towing capacity of up to 17,000 pounds when properly equipped, as detailed in the Official 2025 Silverado 2500 HD Specifications.
Its payload capacity reaches 3,689 pounds, perfect for hauling construction materials or equipment.
The gas engine balances power and affordability, appealing to small business owners and casual users.
However, it’s less fuel-efficient than the diesel option under heavy loads.
6.6L Duramax Turbo-Diesel V8: Unmatched Towing Strength
For maximum performance, the 2025 Chevy Silverado 2500 Engine Options include the 6.6-liter Duramax Turbo-Diesel V8.
This engine produces 470 horsepower at 2,800 RPM and a staggering 975 pound-feet of torque at 1,600 RPM.
The Duramax excels in heavy-duty towing and hauling, offering superior low-end torque for massive loads.
It tows up to 20,000 pounds with a conventional hitch and 22,430 pounds with a fifth-wheel or gooseneck hitch.
With the Max Trailering Package, towing capacity reaches 36,000 pounds, as noted in 2025 Silverado 2500 HD Performance and Towing. Payload capacity ranges from 3,395 to 3,975 pounds, depending on configuration.
The diesel engine’s 25% improved low-end torque ensures effortless acceleration when fully loaded. It also offers better fuel efficiency on long hauls, critical for frequent travelers.
The diesel’s higher initial cost and diesel exhaust fluid (DEF) requirements add to maintenance expenses.
