17 MPG combined isn’t going to win any fuel efficiency awards, but for the 2019 Chevrolet Tahoe K1500 4WD with the 6.2L V8, it’s what you get for a unique blend of capability. This isn’t a vehicle bought by penny-pinchers. It’s for those who need serious towing capacity, seating for the whole family, and the confidence of four-wheel drive, all in a package that can handle anything from a cross-country road trip to hauling a boat to the lake.

City and highway performance

The EPA estimates suggest 14 MPG in the city and 22 MPG on the highway for this particular Tahoe configuration. The lower city figure reflects the thirsty nature of the large-displacement V8 engine under the constant stop-and-go conditions. The 10-speed automatic transmission works hard to keep the engine in its optimal range, but there’s no hiding the fact that you’re moving a substantial amount of weight. On the open road, the highway figure is more reasonable, though still far from great. With careful driving and a light foot, hitting that 22 MPG mark is certainly achievable.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,400 for the 2019 Chevrolet Tahoe K1500 4WD 6.2L V8. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Know that your actual fuel costs will vary significantly depending on your driving habits, the type of driving you do, and the fuel prices in your area. Stop-and-go city driving and frequent towing will push that number higher, while mostly highway cruising might bring it down slightly. See all Chevrolet fuel economy data on this site.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can change significantly. Owners of this Tahoe configuration often report figures that vary from slightly below the EPA estimates to occasionally exceeding them on long highway drives. Consider terrain, driving style, and even tire pressure, and you quickly realize that your mileage may vary. Aggressive acceleration, heavy braking, and neglecting routine maintenance will all contribute to lower fuel economy. Wind resistance, caused by roof racks or cargo carriers, will also noticeably impact fuel consumption, especially at highway speeds.

How it compares

Compared to its contemporaries, the 2019 Tahoe with the 6.2L V8 isn’t exactly winning any efficiency battles. The Ford Expedition with its 3.5L EcoBoost V6 delivers slightly better EPA-estimated numbers, around 17 MPG city and 23 MPG highway in 4×4 guise. The Toyota Sequoia, with its naturally aspirated 5.7L V8, comes in slightly lower, at around 13 MPG city and 17 MPG highway. For Tahoe shoppers, fuel economy is often secondary to power and capability. The 6.2L offers a significant performance advantage over the standard 5.3L V8 found in other Tahoe trims. Buyers who prioritize fuel efficiency above all else might be better served by exploring a smaller SUV or even a crossover. See TAHOE MPG across all years.

Tips to maximize efficiency

Take advantage of the Tahoe’s Eco mode. This mode adjusts the engine and transmission settings to prioritize fuel efficiency, even though it modestly affects acceleration. For daily commuting and light-duty driving, it’s a simple way to save a bit of fuel without sacrificing too much performance.

Regularly check and maintain your tire pressure. Underinflated tires increase rolling resistance, which leads to decreased fuel economy. Refer to the sticker on your driver’s side doorjamb for the recommended tire pressure.

Minimize idling. Modern engines are designed to warm up quickly while driving. Avoiding prolonged idling, whether it’s waiting in the school pickup line or running errands, can save a surprising amount of fuel over time.

Plan your routes strategically. Avoiding stop-and-go traffic and construction zones not only saves time but also improves fuel economy. Using navigation apps to find the most efficient route can make a noticeable difference, especially when traveling in urban areas.

Avoid unnecessary cargo. The heavier the vehicle, the more fuel it consumes. Removing any unnecessary items from the Tahoe, especially heavy objects, will contribute to improved fuel economy. Consider removing roof racks or cargo carriers when they’re not in use, as they increase aerodynamic drag.
