16 MPG combined. Nobody buys a 2023 Chevrolet Tahoe 4WD with the 6.2L V8 expecting Prius-like fuel efficiency. This configuration is for effortless towing, rapid acceleration, and a commanding presence. Fuel economy is secondary, the accepted cost for genuine capability. People buying this Tahoe aren’t agonizing over gas prices; they’re hauling boats, getting families to the ski slopes, or simply appreciate the V8 rumble.

City and highway performance

The EPA estimates for the 2023 Tahoe 6.2L 4WD show the tradeoffs in its design. Expect around 14 MPG in the city. Stop-and-go traffic highlights the Tahoe’s weight. On the highway, it improves to 18 MPG. The 10-speed automatic transmission optimizes fuel economy at cruising speeds, but aerodynamic drag limits gains. These numbers are realistic under normal driving, but aggressive acceleration or heavy loads will lower them.

Annual fuel cost

The EPA estimates the annual fuel cost for this Tahoe configuration at $3,600. This is based on 15,000 miles per year and national average fuel prices. Individual fuel costs will vary depending on local prices and driving habits. If you primarily drive in the city, or if gasoline prices are significantly higher, your annual fuel bill will likely exceed this figure.

Real-world expectations

EPA estimates provide a baseline, but real-world fuel economy often differs. The 16 MPG combined figure is an optimistic average. Owners report figures between 14-17 MPG in mixed driving, with highway trips providing the best results. Towing, particularly at higher speeds, will significantly reduce fuel efficiency, often dropping into the single digits. Tire pressure, ambient temperature, and air conditioning also influence consumption.

How it compares

The 2023 Tahoe 6.2L 4WD’s fuel economy is expected, given its size and power. The Ford Expedition, with its 3.5L EcoBoost V6, achieves around 17 MPG combined in 4WD configuration. A Toyota Sequoia, with its hybrid powertrain, fares slightly better, reaching around 20-22 MPG combined, which is an improvement. However, neither offers the V8 experience as the Tahoe. If you’re considering a GMC Yukon Denali, which also offers a 6.2L engine, the fuel economy will be virtually identical to the Tahoe. For those who want less gas, it might be worth considering a different engine, like the 5.3L V8, or exploring models with rear-wheel drive, but understand that those will trade off on power and towing capability.

Tips to maximize efficiency

The Tahoe 6.2L V8 rewards a gentle driving style. Avoid aggressive acceleration and hard braking, as these consume fuel. Anticipate traffic flow and maintain a steady speed whenever possible. Consider using cruise control on the highway to minimize throttle variations.

Proper maintenance is critical for fuel efficiency. Ensure that your Tahoe’s tires are properly inflated, as underinflated tires increase rolling resistance. Schedule regular oil changes and keep the engine air filter clean. Neglecting these maintenance items can decrease performance and increase fuel consumption.

Minimize unnecessary weight in the vehicle by removing any non-essential items from the cargo area, as added weight directly impacts fuel economy. Similarly, avoid using roof racks unless necessary, as these increase aerodynamic drag.

When towing, keep speeds as low as safely possible. Higher speeds create more aerodynamic drag, reducing fuel efficiency. Use the tow/haul mode on the transmission to optimize shift points for towing, and ensure that the trailer is properly loaded and balanced to minimize sway and drag. The 6.2L engine isn’t straining to pull a load, so lower speeds won’t be a struggle.
