2026 Silverado MPG & Mileage: How Do the 1500, HD, and EV Compare?
If you drive around Waterloo or tow a boat to Lake Delhi, you want a truck that fits your life. But Silverado MPG is not a one-size-fits-all answer. The 2026 Silverado 1500, 2500HD, 3500HD, and the new EV each offer different kinds of efficiency. Here is how they stack up for your commute and weekend plans.
Key Takeaways
- The 2026 Silverado 1500 with the 3.0L Duramax diesel offers the best traditional fuel economy, reaching up to 29 MPG on the highway (2WD).
- Heavy-duty Silverado 2500HD and 3500HD trucks are not EPA-rated, but real-world estimates range from 11 to 17 MPG depending on the engine and load.
- The 2026 Silverado EV changes the game with up to 493 miles of range on some configurations, though towing and cold Iowa winters will reduce that number.
- Rydell Chevrolet in Waterloo has the full Silverado lineup in stock for test drives.
How Does the 2026 Silverado 1500 Compare on MPG?
If you are shopping for the best fuel economy in a traditional gas or diesel truck, the 2026 Silverado 1500 is your starting point. It is the lightest-duty option in the lineup, and it offers multiple powertrains. The most efficient choice by a large margin is the 3.0L Duramax Turbo-Diesel. According to fueleconomy.gov, a 2WD 2025 Silverado with this engine achieves an estimated 23 MPG city and 29 MPG highway. That is genuine long-haul efficiency for commutes on Highway 20 or trips to Des Moines.
Gas engine options are honest but less efficient. The 5.3L V8 and 6.2L V8 trade some MPG for classic V8 power and sound. The 2.7L TurboMax is a solid middle ground for daily driving. But if you put a priority on fuel mileage, the Duramax diesel is the clear winner.
Why Does the Silverado 2500HD and 3500HD Not Have an Official MPG Rating?
If you are looking for a window sticker on a 2026 Silverado 2500HD or 3500HD, you will not find a city or highway MPG number. These trucks are classified as heavy-duty vehicles with a Gross Vehicle Weight Rating (GVWR) above 8,500 pounds. The EPA does not test them for fuel economy because their fuel consumption changes so much based on how you use them.
So what can you expect? Real-world reports typically put the 6.6L gas V8 in the 11 to 14 MPG range. The 6.6L Duramax diesel is usually a bit better, averaging around 14 to 17 MPG when unloaded. These numbers drop quickly when you are towing or hauling heavy loads.
Honest Advice for Heavy-Duty Buyers
If fuel economy is your top concern, consider the 1500 or the EV. But if you need to tow a 15,000-pound trailer across the state or haul construction materials, the HD trucks are built for that job, not for MPG bragging rights.
What Is the Real-World Range of the 2026 Silverado EV?
The 2026 Silverado EV is a completely different animal. You do not buy gas, but you need to think about range and MPGe (miles per gallon equivalent). FuelEconomy.gov shows several configurations. One model offers 493 miles of total range, making it a viable option for daily drivers and even some longer trips. Other trims offer ranges around 385 to 424 miles.
There is a catch. Range estimates are ideal numbers. A cold Iowa winter, high-speed driving on I-380, or a heavy trailer will reduce your range significantly. If you do most of your driving around Waterloo, the EV is a great choice. But if you routinely tow heavy loads across the state, a diesel 1500 or HD might be a safer bet.
How Does Towing Affect Silverado MPG and Range?
Towing is the great equalizer. A properly equipped 2026 Silverado 1500 can tow up to 13,300 pounds. That is a lot of boat or camper. But when you hook up a trailer, the MPG goes down. You might see 14 to 16 MPG on flat ground with a diesel, and considerably less in hilly terrain. The 2500HD and 3500HD are not rated for MPG, but their diesel engines are designed to handle heavy loads without straining, which helps maintain reasonable fuel consumption compared to the gas V8s.
| 2026 Silverado Model | Best Fuel Economy / Range | EPA Rating? | Best For |
|---|---|---|---|
| 1500 3.0L Duramax | 23 City / 29 Highway MPG | Yes | Commuting, light towing, long road trips |
| 1500 Gas V8 (5.3L/6.2L) | 15-17 MPG combined | Yes | Daily driving with classic V8 power |
| 2500HD / 3500HD | ~14-17 MPG (diesel, unloaded) | No | Heavy towing, payload, construction, farm work |
| Silverado EV | Up to 493 miles range | Yes (MPGe) | Daily commuting, local trips, gas station avoidance |

Frequently Asked Questions About Silverado MPG and Towing
Which 2026 Silverado gets the best highway MPG?
The 2026 Silverado 1500 with the 3.0L Duramax diesel and rear-wheel drive offers the best traditional fuel economy. EPA estimates show it can achieve up to 29 MPG on the highway.
Why doesn't the Silverado 2500HD have an EPA MPG rating?
Heavy-duty trucks like the 2500HD and 3500HD have a GVWR over 8,500 pounds and are exempt from EPA fuel economy testing. Their fuel consumption is highly dependent on load and towing, so a single MPG number would be misleading.
How far can the 2026 Silverado EV go on a full charge?
According to EPA data, some 2026 Silverado EV configurations offer up to 493 miles of range, while others provide 385 to 424 miles, depending on the battery pack and equipment.
Does towing a trailer reduce Silverado MPG and EV range?
Yes. Towing significantly reduces both MPG in gas/diesel models and range in the EV. A 1500 Duramax that gets 29 MPG unloaded might see 14-16 MPG when towing. EV range can drop by 50% or more with a heavy trailer.
What is the towing capacity of the 2026 Silverado 1500?
