17 MPG combined is what you get when you choose four-wheel drive and a reliable V8 in a full-size SUV. The 2023 Chevrolet Tahoe 4WD with the 5.3L V8 isn’t designed to save fuel; it’s built to haul families, tow trailers, and handle challenging weather. Owners value space, capability, and traditional truck-like performance more than saving money at the pump. Families with multiple children, frequent campers, and those who live in areas with harsh winters are the main buyers. They accept the fuel economy trade-off because no other vehicle does what they need.

City and highway performance

The EPA estimates for the 2023 Tahoe 4WD 5.3L V8 are 15 MPG in the city and 20 MPG on the highway. The city figure reflects the stop-and-go of urban driving, where the Tahoe’s weight and engine size require more fuel to accelerate. The highway mileage is better, helped by the 10-speed automatic transmission that allows the engine to run at lower RPMs at higher speeds. However, even on the open road, the Tahoe’s shape isn’t helping its fuel economy.

Annual fuel cost

According to the EPA, the annual fuel cost for this Tahoe is $2,600. This is based on driving 15,000 miles per year and using national average fuel prices. Gas price changes will affect this number. If you live in an area with higher fuel costs, or if you drive more than 15,000 miles annually, you will likely spend more than this estimate. Lower fuel prices or reduced mileage will result in less money spent on fuel. It’s a benchmark for understanding the ownership costs.

Real-world expectations

The EPA provides an estimate, but real-world fuel economy varies. Your driving style, terrain, and cargo weight influence the numbers you see. Fast acceleration, frequent towing, and driving in hilly areas will reduce fuel economy. A careful driver who uses their Tahoe for highway driving can achieve numbers closer to, or even slightly above, the EPA’s 20 MPG highway estimate. The condition of your vehicle, including tire pressure and regular maintenance, also matters. Explore all Chevrolet fuel economy data.

How it compares

The Tahoe’s fuel economy should be considered with its competitors. The Ford Expedition 4×4 with its 3.5L EcoBoost V6 is rated at 19 MPG combined, a slight advantage. The Nissan Armada 4×4, with its 5.6L V8, gets a similar 16 MPG combined. Even the GMC Yukon, which is similar to the Tahoe, mirrors its 17 MPG combined rating when equipped with the 5.3L V8 and 4WD. This comparison matters for buyers comparing these full-size SUVs, showing that fuel economy differences are often small within the segment, despite engine choices. Consider the TAHOE MPG across all years.

Tips to maximize efficiency

Avoid fast acceleration and hard braking. The Tahoe is heavy, and speed changes require energy. Gradual acceleration saves fuel, especially in city driving.

Keep proper tire inflation. Underinflated tires increase rolling resistance, which impacts fuel economy. Check your tire pressure and inflate them to the recommended PSI listed on the driver’s side doorjamb.

Minimize idling. Letting the Tahoe idle for long periods wastes fuel. If you’re going to be stopped for more than a minute or two, turn off the engine.

Consider cruise control on the highway. Consistent speed can help fuel economy on long drives. Be mindful of hills, as cruise control may downshift to maintain speed and reduce fuel efficiency.

Reduce weight. Extra cargo adds weight, requiring more fuel to accelerate and maintain speed. Remove unnecessary items to improve fuel efficiency.
