The 2025 Chevrolet Tahoe 4WD with the 6.2L V8 gets 16 MPG combined. This vehicle isn’t designed for fuel efficiency; it’s a tool for hauling and a statement. It’s a choice for those prioritizing capability, space, and the sound of an American V8 over fuel savings.

City and highway performance

The EPA estimates 14 MPG in the city and 18 MPG on the highway. These figures are best-case scenarios under controlled conditions. Expect the city number to be lower in real-world driving, especially with frequent stops or fast acceleration. The highway figure is more achievable on longer trips if you resist the urge to use the 6.2L engine’s passing power. The 10-speed automatic transmission tries to keep the engine efficient, but it can’t escape the physics of moving nearly three tons of SUV.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,600 for the 2025 Chevrolet Tahoe 4WD 6.2L. This is based on driving 15,000 miles per year and using the national average fuel price for regular gasoline. Remember this is an estimate. If you drive more, tow often, or live in an area with higher fuel prices, your actual costs may be higher. If you primarily use the Tahoe for short trips around town, you might see slightly better real-world fuel economy.

Real-world expectations

Expect to see numbers slightly below the EPA estimates. The 6.2L V8 encourages drivers to accelerate more. Towing, a common use for the Tahoe, will significantly impact fuel economy, potentially dropping it into the single digits. Many Tahoe owners accept these trade-offs for the vehicle’s capabilities; they’re buying not just transportation but also a lifestyle.

How it compares

No large, body-on-frame SUV is very fuel-efficient. The Ford Expedition with its 3.5L EcoBoost V6 gets a slightly better 17 MPG combined, a small difference that adds up over a year. The Toyota Sequoia, known for reliability, isn’t significantly better in fuel economy. The GMC Yukon, essentially a Tahoe twin, offers similar MPG figures, depending on the engine and drivetrain. If fuel efficiency is important in a large SUV, exploring all Chevrolet fuel economy data is a good idea. Those drawn to the Tahoe 6.2L are often willing to trade efficiency for power and the V8 experience. For a broader perspective, review TAHOE MPG across all years.

Tips to maximize efficiency

Improve fuel economy by driving smoothly and avoiding quick acceleration. The Tahoe’s 10-speed transmission shifts early, so let it do its job. Accelerate only when necessary.

Regular maintenance is critical, especially keeping the tires properly inflated. Underinflated tires will increase rolling resistance, reducing fuel economy. Check your tire pressures and inflate them to the recommended levels on the door jamb placard.

If your Tahoe has cylinder deactivation, enable it. The impact might be small, but every bit helps. Understanding the vehicle’s settings can make a difference.

Remove unnecessary weight. Extra cargo, especially heavy items, reduces fuel economy. Remove anything you don’t need from the cargo area and passenger seats. A lighter vehicle is more efficient.

Think about your driving routes. Avoiding rush hour traffic and opting for routes with consistent speeds can significantly improve fuel economy compared to stop-and-go city driving. Planning trips and avoiding congested areas can save time and money.
