The 2025 Chevrolet Tahoe 2WD with the 5.3L V8 gets 17 MPG combined. No one buys a Tahoe solely for fuel efficiency. They buy it for its combination of space, towing capability, and truck-based durability in an SUV. The 5.3L V8 is a known quantity and a reliable workhorse. The two-wheel-drive configuration shaves a little weight while providing good traction for most everyday driving. This drivetrain choice prioritizes function over frugality, and capability over compromise.

City and highway performance

The EPA estimates 15 MPG in the city and 20 MPG on the highway. Stop-and-go driving will negatively affect fuel economy, as the Tahoe’s weight and V8 engine consume more fuel. Expect to see the fuel gauge drop during low-speed urban trips. Highway cruising is better. The 10-speed automatic transmission helps keep the engine in its optimal power band, allowing for better fuel economy when maintaining consistent speeds. If you drive mostly highway miles, hitting that 20 MPG mark is achievable.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Chevrolet Tahoe 2WD 5.3L 8-cyl at $2,600. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also uses the national average fuel price at the time of calculation. Your individual fuel costs will vary based on your driving habits, the amount you drive, and local fuel prices, but the $2,600 figure provides a standardized comparison point.

Real-world expectations

While the EPA estimates offer a baseline, real-world MPG will vary. Aggressive driving, frequent towing, or carrying heavy loads will negatively affect fuel consumption. Similarly, extreme weather conditions, such as winter driving with snow tires, can also reduce efficiency. Regular maintenance, including proper tire inflation and timely oil changes, will help ensure that your Tahoe runs efficiently.

How it compares

The Tahoe’s fuel economy is lower than some of its competitors. A Ford Expedition with its 3.5L EcoBoost V6 manages 17 MPG combined while offering similar space and towing. The Toyota Sequoia, with its hybrid powertrain, achieves a more appealing 22 MPG combined, but its initial MSRP is higher. Even within Chevrolet, the GMC Yukon Denali with the 3.0L Duramax diesel engine achieves around 23 MPG combined. The Tahoe buyer likely prioritizes the proven nature of the 5.3L V8 and its lower upfront cost compared to the diesel or hybrid alternatives.

Tips to maximize efficiency

Gentle acceleration and braking are key. Avoid sudden bursts of speed to save fuel. Anticipate traffic flow and coast whenever possible to conserve momentum and reduce the need for hard braking. The Tahoe is a large vehicle, so smooth driving will improve its fuel consumption.

Use the Tahoe’s cruise control on the highway. Maintaining a consistent speed improves fuel efficiency and reduces driver fatigue on longer journeys. Set your desired speed, and let the vehicle manage the throttle for more relaxed and economical highway driving.

Regularly check your tire pressure. Underinflated tires increase rolling resistance, which hurts fuel economy. Consult the sticker on your driver’s side doorjamb for the recommended tire pressure for your Tahoe. Properly inflated tires can improve fuel efficiency by up to 3%.

Minimize idling time. If you’re going to be stopped for more than a minute or two, turn off the engine. Idling consumes fuel without covering any distance. Modern engines can be restarted without significant wear, making it more efficient to switch off the engine during extended stops.

Consider using the available driver selectable mode. Several driving modes may be available, and each setting may greatly affect fuel economy.
