15 MPG combined. Let’s be clear: nobody buys a 2024 Chevrolet Silverado 4WD ZR2 with the 6.2L V8 thinking they’re going to win any fuel economy contests. This truck exists to conquer trails, ford streams, and generally laugh in the face of terrain that would strand lesser vehicles. The ZR2 is a statement, a commitment to off-road capability, and its fuel consumption is simply the price of admission. Its buyers are more concerned with ground clearance and skid plates than saving a few dollars at the pump.

City and highway performance

The EPA estimates peg the Silverado ZR2 at 14 MPG in the city and 17 MPG on the highway. These figures reflect the realities of its chunky off-road tires, considerable weight, and the ever-ready power of the 6.2L V8. The city number is a realistic representation of stop-and-go driving, where the engine is constantly working to overcome inertia. The highway figure, while slightly better, is still hampered by the truck’s aerodynamics and the drag from those aggressive tires. Your mileage will vary depending on driving style, terrain, and even tire pressure.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 Chevrolet Silverado ZR2 4WD is $3,850. This is based on driving 15,000 miles per year and using national average fuel prices. This figure serves as a helpful benchmark, but keep in mind that local fuel prices can fluctuate quite a bit, having a direct impact on your real-world costs. If you drive fewer miles, your annual fuel cost will be lower. If you frequently tow or spend a lot of time in low-range 4×4, expect to exceed that $3,850 estimate by a significant margin.

Real-world expectations

While the EPA provides a baseline, real-world MPG for the ZR2 often falls short of the official numbers. Aggressive driving, heavy towing, and spending time off-road will all negatively impact fuel economy. Owners who primarily use their ZR2 as a daily driver on paved roads can expect to see figures closer to the EPA estimates, but don’t be surprised if you average closer to 12-13 MPG in mixed driving. The sheer joy of unleashing the 6.2L V8 often outweighs any concern for maximizing fuel efficiency.

How it compares

Compared to other off-road-focused trucks, the Silverado ZR2’s fuel economy is in line with expectations. The Ram 1500 TRX, with its supercharged V8, achieves a dismal 12 MPG combined. A Ford F-150 Raptor, despite its smaller turbocharged engine, manages only 15 MPG combined. Even the Toyota Tundra TRD Pro, though more fuel-efficient than the full-bore V8 options, still only nets around 18 MPG combined. These differences may be meaningful to some buyers, helping them determine their final choice, but typically those who prioritize capability are only marginally concerned with fuel economy.

Tips to maximize efficiency

Despite the ZR2’s nature, there are ways to improve fuel economy. One simple adjustment is to ensure your tires are properly inflated. The ZR2’s off-road tires have a lower maximum PSI than most passenger tires, so double-check the sticker on your door and maintain the correct pressure. Regular maintenance, including air filter replacement and oil changes, also contributes to optimal engine performance and efficiency.

Avoid aggressive acceleration and braking. The 6.2L V8 responds enthusiastically to throttle input, but every surge of power comes at a cost. Smooth and steady driving will significantly reduce fuel consumption, especially in city driving where constant acceleration and deceleration take a toll.

Reduce any unnecessary weight. Carrying extra gear or equipment in the bed adds to the overall load, forcing the engine to work harder. Only carry essential items or remove unnecessary cargo when not needed. and removing aftermarket accessories like heavy-duty bumpers and roof racks when not being used will also improve MPG.

When possible, use cruise control on the highway. Maintaining a consistent speed minimizes fluctuations in fuel consumption. The ZR2’s 10-speed automatic transmission is designed to keep the engine in its most efficient operating range, so let it do its job and resist the urge to constantly adjust your speed.
