Jennings Auto Group - Which engine should you choose on the 2026 Chevrolet Silverado 2500 HD in Beardstown, IL?
At Jennings Auto Group in Beardstown, IL, the most common question we hear from in-market truck shoppers considering the 2026 Chevrolet Silverado 2500 HD is simple: which engine is the better fit for my work and weekend towing? The Silverado 2500 HD offers two serious powerplants — a 6.6-liter gas V-8 and the available 6.6-liter Duramax Turbo-Diesel V-8 — each paired with an Allison 10-speed automatic. Choosing the right one comes down to how often you tow, what you’re towing, and how you use your truck day to day around Cass County and beyond.
The gas V-8 delivers 401 horsepower and 464 lb-ft of torque with confident response for daily hauling, farm chores, and jobsite duty. The available Duramax Turbo-Diesel steps up to 470 horsepower and 975 lb-ft of torque and is the go-to choice for frequent, heavy trailering. Across the Silverado HD line, the gasoline setup can tow up to 17,400 pounds, while the diesel can pull up to 36,000 pounds when properly equipped. Actual maximums vary by cab, bed, axle configuration, and hitch setup, and the top figure is reserved for specific Silverado HD configurations — ask our team to map your needs to the right 2500 HD build.
If your routine near Beardstown includes daily commuting, occasional equipment trailers, or a camper a few weekends each season, the gas V-8 is smooth, straightforward, and strong. If you’re regularly pulling livestock, a large fifth-wheel, or heavy construction gear, the Duramax Turbo-Diesel’s low-rpm torque, engine braking characteristics, and confident highway passing make the long miles easier. Both engines benefit from the Allison 10-speed automatic’s smart gearing, delivering composed shifts with or without a load.

Beyond raw power, the 2026 Silverado 2500 HD builds confidence with towing technology designed to make hard work feel easier. Available features include a 14-camera surround-view system with a Transparent Trailer View that can help when merging or maneuvering in tight lots, plus Adaptive Cruise Control that’s optimized for trailering. The truck’s Google-based infotainment system supports Apple CarPlay and Android Auto, and lets you store trailer profiles to monitor maintenance items and check light tests. On LT, LTZ, Trail Boss, High Country, and ZR2 models, a 13.4-inch touchscreen is standard, giving you a big, clear interface for trailering apps and camera views.
If you want added off-pavement assurance around farm fields or jobsite access roads, look to off-road-tuned variants like ZR2 or ZR2 Bison. Chevrolet has also introduced Polar White Tricoat for 2026, joining a robust color palette that pairs well with the Silverado HD’s bold stance. No matter how you configure it, the cab remains spacious with easy-to-use switchgear, smart storage solutions, and available comforts like heated and ventilated front seats and a heated steering wheel to take the edge off Midwest winters.
- Define your trailer: Know your trailer’s loaded weight and tongue or pin weight, plus how often you plan to tow near Beardstown or on long interstate runs.
- Match the build: Choose the cab, bed, axle, and hitch configuration that aligns with your trailer. Our team can spec the right 2500 HD setup for stability and control.
- Drive both engines: A back-to-back test drive — ideally with a representative trailer — will quickly clarify whether the gas or Duramax diesel suits your routine best.

Frequently Asked Questions:
Is the Allison 10-speed automatic the same with both engines?
Yes. Both the 6.6L gas V-8 and the available 6.6L Duramax Turbo-Diesel V-8 pair with an Allison 10-speed automatic, tuned to keep each engine in its ideal power band for towing and daily driving.
Will choosing the Duramax diesel change my payload rating?
Diesel hardware adds weight to the truck, which can affect payload. Exact figures depend on cab, bed, drivetrain, and equipment. We will show you the door-jamb label and build-specific charts so you know your precise payload capacity.
Can the 2026 Silverado 2500 HD tow a fifth-wheel or gooseneck?
When properly equipped, the Silverado 2500 HD can be set up for fifth-wheel or gooseneck towing. We will help you select the correct prep, hitch, and suspension components for your trailer and verify clearances before you take delivery.
Does the EPA rate fuel economy for the 2500 HD?
Vehicles in this class are not EPA-rated. Real-world mpg varies with load and conditions; in prior highway testing, a Silverado 2500 Duramax diesel achieved 18 mpg at 75 mph. Your results will vary based on trailer weight, speed, terrain, and weather.
Is Adaptive Cruise Control available for towing?
Adaptive Cruise Control is available and optimized for trailering on the Silverado HD, enhancing long-haul comfort when traffic ebbs and flows on I-72 or Route 67.
