15 MPG combined. Let’s be frank: If that number deters you from considering the Silverado ZR2, you’re simply not the target customer. This isn’t a truck bought for maximizing efficiency around town. The ZR2 is purpose-built for off-road domination, prioritizing ruggedness, capability, and the unmistakable roar of a 6.2L V8 over saving fuel. The people who buy this truck want serious off-road ability coupled with the comfort and usability of a pickup, and they understand the compromise.

City and highway performance

The EPA estimates 14 MPG in the city and 17 MPG on the highway for the 2025 Chevrolet Silverado 4WD ZR2. Stop-and-go traffic will clearly tax the ZR2’s fuel consumption due to its weight and large displacement engine. Highway driving offers a marginal improvement, but keep in mind that the ZR2’s off-road tires and suspension are not optimized for aerodynamic efficiency at higher speeds. Achieving the EPA’s 17 MPG will require a light foot and a relatively flat route; encountering hills or strong headwinds will have a noticeable impact.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2025 Chevrolet Silverado 4WD ZR2 is $3,850. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Fuel prices fluctuate, and individuals drive different amounts each year. Therefore, this $3,850 figure is a useful estimate for comparison purposes, but your actual fuel expenses may vary significantly.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy will vary depending on driving habits, terrain, and vehicle load. ZR2 owners who frequently engage in off-road driving should expect to see fuel consumption even lower than the EPA’s city rating. Installing larger or more aggressive tires, adding aftermarket accessories, or regularly towing will further impact fuel economy. Those who are mindful of their driving style and primarily use the ZR2 for on-road commuting may see figures closer to the EPA estimates, but exceeding them will be a challenge.

How it compares

The Silverado ZR2 occupies a unique niche, offering off-road capability comparable to the Ford F-150 Raptor. The Raptor, with its 3.5L EcoBoost V6, manages a slightly better 16 MPG combined. Choosing the ZR2 means prioritizing the naturally aspirated V8 experience and accepting the associated fuel consumption penalty. Compared to other full-size trucks with similar engines but less off-road hardware, the ZR2 is predictably less efficient. A standard Silverado 1500 with the same 6.2L V8 can achieve around 17 MPG combined in 4×4 form when not equipped with the ZR2 package. The Ram 1500 TRX, with its supercharged 6.2L V8, is even thirstier, rated at a dismal 12 MPG combined. For those seeking better fuel economy in a full-size truck, exploring all all Chevrolet fuel economy data is recommended, or perhaps considering the turbocharged four-cylinder Silverado options.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The ZR2’s powerful engine responds quickly to throttle inputs, but excessive acceleration wastes fuel. Anticipate traffic conditions and maintain a steady speed whenever possible.

Maintain proper tire inflation. ZR2’s off-road tires are designed for grip, not rolling resistance. Ensuring they are inflated to the recommended pressure minimizes rolling resistance and improves fuel economy on paved surfaces.

Reduce unnecessary weight. Carrying extra weight in the truck bed or cab impacts fuel economy. Remove any unnecessary items to minimize the load the engine has to carry. Also, avoid using roof racks unless necessary, as they create additional drag.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long highway drives. It minimizes fluctuations in throttle position, leading to more efficient fuel consumption.

Consider your route and driving conditions. Avoiding stop-and-go traffic and hilly terrain can significantly improve fuel economy. Plan routes that minimize these conditions whenever possible, especially during long trips.
