17 MPG combined is what buyers of the 2025 Chevrolet Tahoe 2WD with the 6.2L V8 can expect. This number shows the Tahoe’s main purpose: moving many people and cargo with serious capability. This isn’t a fuel-sipping crossover; it’s a full-size SUV designed for families who need space, towing capacity, and the reassurance of a reliable, truck-based platform. The fuel economy is a compromise they understand and are often willing to accept.

City and highway performance

The EPA estimates this specific Tahoe configuration gets 15 MPG in the city and 20 MPG on the highway. The city figure reflects the stop-and-go driving where the Tahoe’s weight and large engine are most penalized. The highway MPG, while still not great, is a more realistic expectation for longer trips. The 10-speed automatic transmission tries to keep the engine in its most efficient operating range, but physics ultimately wins. The power of the 6.2L engine is undeniable, and contributes to the poor fuel economy.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2025 Chevrolet Tahoe 2WD 6.2L is $3,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. That’s a lot of money, and higher than smaller SUVs or even other Tahoes with smaller engines. Buyers need to include this expense in their budget and decide if the utility offered justifies the cost.

Reviewing the TAHOE MPG across all years might show whether a different year offers better gas mileage.

Real-world expectations

The EPA provides an estimate, but real-world fuel economy can vary. Driving style, traffic, and even air conditioning affect fuel consumption. Aggressive acceleration and frequent braking will lower MPG, and towing will have a big impact. Don’t be surprised to see numbers below the EPA estimates if you regularly do these things.

How it compares

The Tahoe’s fuel economy is low for its class. For example, the Ford Expedition with its 3.5L EcoBoost V6 achieves about 17 MPG combined, which is similar, but buyers often see better MPG in the Expedition than in the Chevrolet. A Toyota Sequoia with its hybrid powertrain is rated around 22 MPG. Even the GMC Yukon, which shares the Tahoe’s platform, but uses the 5.3L V8, gets roughly 18 MPG combined. This difference matters to buyers on a budget who need a large SUV. It may change their minds when looking at all Chevrolet fuel economy data.

Tips to maximize efficiency

Gentle acceleration and smooth braking save fuel in a big SUV like the Tahoe. Avoid sudden speed and watch traffic to brake less. City driving is very important here as stop-and-go driving can hurt gas mileage.

Tire inflation affects gas mileage. Check your tire pressure and match it to the pressure on the driver’s side doorjamb. Low tires create more rolling resistance, which lowers fuel economy.

Don’t idle if you can avoid it! If you’re stopped for more than a minute, turn off the engine. Idling wastes fuel without moving the car, which hurts your overall MPG.

Cruise control on the highway keeps a consistent speed. This helps with fuel usage by avoiding speed changes. Watch traffic, and disengage cruise control when necessary.

Don’t carry extra weight in the Tahoe. The heavier the load, the harder the engine works, which lowers fuel economy. Remove extra items from the vehicle to improve efficiency.
