2026 Chevrolet Silverado 1500 Engine Options: Power, Towing and EPA-Estimated MPG
The 2026 Chevrolet Silverado 1500 offers four engine choices. You can pick the standard 2.7L TurboMax turbocharged four-cylinder, the 5.3L EcoTec3 V8, the 6.2L EcoTec3 V8, or the Duramax 3.0L Turbo-Diesel inline-six. Each one is built around a different priority. Some favor everyday efficiency. Others are built for maximum trailering.
Choosing between them gets easier once you know two things. First, which transmission each engine uses. Second, which trims each engine is actually offered on. Engine availability across the nine 2026 Silverado 1500 trims is not a simple ladder. The TurboMax is standard on six trims. But the 5.3L V8 comes standard on LTZ and High Country, and the Duramax diesel comes standard on the ZR2. This guide breaks down the specs, the EPA-estimated fuel economy, and the trailering ratings for each engine.
Which Engines Are Available on the 2026 Silverado 1500?
The 2.7L TurboMax
The TurboMax 2.7L turbocharged inline-four produces 310 horsepower and 430 lb-ft of standard torque. Chevrolet rates that torque figure as best-in-class. It pairs with an eight-speed automatic transmission. The engine also uses Active Fuel Management and Automatic Stop/Start to cut fuel use under light load.
The Two EcoTec3 V8s
The 5.3L EcoTec3 V8 produces 355 horsepower and 383 lb-ft of torque. The 6.2L EcoTec3 V8 steps up to 420 horsepower and 460 lb-ft. Both V8s use Dynamic Fuel Management. That system can run the engine in 17 different cylinder patterns, rather than simply switching between eight-cylinder and four-cylinder modes.
The Duramax 3.0L Turbo-Diesel
The Duramax 3.0L Turbo-Diesel inline-six produces 305 horsepower and 495 lb-ft of torque. That is the highest torque figure in the lineup. Chevrolet also rates it as the only diesel engine in its class. The 5.3L, the 6.2L and the Duramax all pair with a 10-speed automatic.
Engine Availability by Trim
| Engine | Horsepower | Torque | Transmission | Standard On | Available On |
|---|---|---|---|---|---|
| 2.7L TurboMax | 310 hp | 430 lb-ft | 8-speed automatic | WT, Custom, Custom Trail Boss, LT, RST, LT Trail Boss | Standard application only — no additional trims |
| 5.3L EcoTec3 V8 | 355 hp | 383 lb-ft | 10-speed automatic | LTZ, High Country | WT (Double Cab and Crew Cab), Custom Trail Boss, LT, RST, LT Trail Boss |
| 6.2L EcoTec3 V8 | 420 hp | 460 lb-ft | 10-speed automatic | Available application only — not standard on any trim | RST (Crew Cab 4×4), LT Trail Boss, LTZ (4×4), ZR2, High Country (4×4) |
| Duramax 3.0L Turbo-Diesel | 305 hp | 495 lb-ft | 10-speed automatic | ZR2 | Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, High Country |

Which 2026 Silverado 1500 Engine Gets the Best EPA-Estimated Fuel Economy?
The Duramax 3.0L Turbo-Diesel is the efficiency leader. It delivers up to an EPA-estimated 23 mpg city and 28 mpg highway in rear-wheel drive. Chevrolet rates that EPA-estimated 28 mpg highway figure as best-in-class among full-size light-duty pickups.
That rating is configuration-specific. It is not a blanket number. The diesel earns its top EPA-estimated ratings on the LT, RST, LTZ and High Country trims in rear-wheel drive. On the off-road trims, the same engine rates lower. The lift, tires and hardware that make those trucks capable also cost efficiency.
How the Gasoline Engines Compare
Among the gasoline engines, the TurboMax leads. It returns an EPA-estimated 18 mpg city and 21 mpg highway in rear-wheel drive. Active Fuel Management and the eight-speed automatic help trim consumption during light cruising. The two V8s rely on Dynamic Fuel Management instead, shutting down cylinders when full power is not needed.
For drivers covering long highway miles through the freight and distribution corridors around Ontario, the diesel makes the strongest case. It combines long range with low-end torque.
EPA-Estimated Fuel Economy by Trim
| Trim | EPA-Estimated Gasoline (City / Hwy) | EPA-Estimated Duramax Diesel (City / Hwy) |
|---|---|---|
| Work Truck | 18 / 21 mpg | Diesel not offered — gasoline engines only |
| Custom | 18 / 21 mpg | Diesel not offered — gasoline engines only |
| Custom Trail Boss | 16 / 17 mpg | 21 / 24 mpg |
| LT | 17 / 21 mpg | 23 / 28 mpg |
| RST | 18 / 21 mpg | 23 / 28 mpg |
| LT Trail Boss | 16 / 17 mpg | 22 / 26 mpg |
| LTZ | 16 / 21 mpg | 23 / 28 mpg |
| High Country | 16 / 21 mpg | 23 / 28 mpg |
| ZR2 | 14 / 17 mpg | 20 / 23 mpg |
Gasoline figures reflect each trim’s standard gasoline engine on standard tires. Figures reflect the most efficient drivetrain available on each trim — rear-wheel drive where it is offered, while Custom Trail Boss, LT Trail Boss and ZR2 are four-wheel drive only. Ratings vary by engine, drivetrain, tires and equipment. Compare official ratings at fueleconomy.gov, the EPA and U.S. Department of Energy fuel economy database.
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
How Much Can Each 2026 Silverado 1500 Engine Tow?
Maximum trailering depends on the engine. It also depends on cab, bed, drivetrain, wheels, and whether the Max Trailering Package is fitted. The headline number for the 2026 Silverado 1500 is 13,300 pounds. Only one configuration reaches it.
Maximum Conventional Towing by Engine
| Engine | Max Conventional Towing | Configuration Required |
|---|---|---|
| 2.7L TurboMax | 9,500 lbs | Regular Cab Long Bed, 2WD |
| 5.3L EcoTec3 V8 | 11,400 lbs | Double Cab Standard Bed, 2WD, with Max Trailering Package |
| 6.2L EcoTec3 V8 | 13,200 lbs | Crew Cab Short Bed or Crew Cab Standard Bed, 4WD, with Max Trailering Package and 20-inch wheels; Chevrolet footnotes this rating to RST configurations |
| Duramax 3.0L Turbo-Diesel | 13,300 lbs | Double Cab Standard Bed, 2WD, with Max Trailering Package and 20-inch wheels |
Maximum trailering ratings per Chevrolet’s official 2026 Silverado 1500 Max Trailering chart.
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
Two Details Buyers Often Miss
First, the 13,300-pound rating belongs to the Duramax diesel alone. The 6.2L V8 tops out slightly lower, at 13,200 pounds.
Second, the off-road trims carry much lower ratings than the lineup maximum. A ZR2 does not tow what the headline figure suggests. Is trailering your main reason for buying? Our 2026 Silverado 1500 towing capacity guide covers ratings by configuration in more depth.
Trailering Technology
The Silverado 1500 offers up to eight cameras with as many as 14 available views, available on LT, RST, LT Trail Boss, LTZ, ZR2 and High Country. Trailer Side Blind Zone Alert is also available. It provides side-mirror alerts when a moving vehicle is detected in the trailer’s blind zone.

Safety or driver assistance features are no substitute for the driver’s responsibility to operate the vehicle in a safe manner. The driver should remain attentive to traffic, surroundings and road conditions at all times. Visibility, weather, and road conditions may affect feature performance. Read the vehicle Owner’s Manual for more important feature limitations and information.
Which Engine Offers the Best Everyday Value?
Want capability without stepping up to a V8 or diesel? The TurboMax makes the strongest all-around case. It is standard on six of the nine trims. Chevrolet rates its 430 lb-ft of torque as best-in-class standard torque.
Chevrolet also publishes its maximum available payload rating with this engine. A Regular Cab Long Bed 2WD with the TurboMax carries up to 2,260 pounds. Payload is limited by what is left under the truck’s weight rating, so lighter cab, bed and drivetrain configurations carry more.
Bed and Payload Specifications
| Specification | Figure | Notes |
|---|---|---|
| Maximum payload | 2,260 lbs | Regular Cab Long Bed, 2WD, with the TurboMax engine |
| Durabed cargo volume | 89.1 cu ft | Chevrolet-rated best-in-class standard cargo volume |
| Bed tie-downs | 12 standard | Rated 500 lbs per corner |
| Multi-Flex Tailgate positions | 6 configurations | Available; includes a full-width step and an inner-gate work surface |
| Multi-Flex step capacity | 375 lbs | Full-width inner-gate step, folded down |
