Owning a 2023 GMC Yukon 4WD with the 5.3L V8 means accepting 17 MPG combined. No one buys this Yukon expecting Prius-like efficiency, but that figure shows the trade-off you’re making for vast interior space, strong towing capability, and the imposing presence that only a full-size SUV can deliver. Buyers prioritizing fuel savings look elsewhere. Yukon buyers, however, tend to value capability and space above all else.

City and highway performance

The EPA estimates offer a breakdown of where this Yukon 4WD is most and least efficient. The city MPG rating of 15 reflects the energy-intensive nature of stop-and-go driving with a heavy vehicle. Expect frequent trips to the gas station if your Yukon mainly tackles urban environments.

The 20 MPG highway figure shows some improvement because the Yukon can settle into a more efficient cruising speed. The 10-speed automatic transmission helps here, keeping the engine in its sweet spot for efficiency when possible. However, even on the open road, the Yukon’s size and weight mean that aerodynamic drag and rolling resistance are always factors.

Annual fuel cost

According to the EPA, expect to spend around $2,600 per year on fuel for this Yukon configuration. This figure is based on driving 15,000 miles annually, with 55% of those miles driven in the city and 45% on the highway. It also assumes national average fuel prices. Of course, your own fuel costs may be higher or lower depending on your driving habits, the type of driving you do, and local fuel prices.

However, $2,600 provides a reasonable benchmark for budgeting purposes. Be sure to factor in potential fuel price fluctuations when projecting your long-term ownership costs.

Real-world expectations

While the EPA estimates provide a useful starting point, your real-world YUKON MPG across all years will likely vary. Aggressive acceleration, frequent towing, and carrying heavy loads will all negatively impact fuel economy. Conversely, gentle driving, consistent highway speeds, and proper tire inflation can help you get closer to the EPA estimates, or even slightly exceed them.

Payload and towing have a significant effect, and pushing the engine hard to merge or tackle hills will instantly drop mileage. Weather conditions can play a role, with cold temperatures often reducing fuel efficiency.

How it compares

The GMC Yukon’s fuel economy stacks up against its direct competitors in predictable ways. A Ford Expedition 4×4 with the standard 3.5L EcoBoost V6 is rated at 19 MPG combined, slightly better, although real-world mileage can vary based on driving style. The Toyota Sequoia, with its new hybrid powertrain, achieves a notably higher 22 MPG combined, though at a higher price point and with a different driving experience. The Jeep Wagoneer 4×4, with its 5.7L V8, mirrors the Yukon’s 17 MPG combined, showing that large, V8-powered SUVs generally inhabit the same fuel economy range.

These small differences might sway shoppers, but it usually comes down to brand loyalty, features, and capability needs more than a few miles per gallon. Comparing all Gmc fuel economy data can highlight the differences in fuel efficiency across the entire model lineup.

Tips to maximize efficiency

Given that you’ve accepted the realities of owning a large SUV, there are still steps you can take to optimize fuel economy. Gradual acceleration and anticipation of traffic conditions are key. Avoid hard braking and sudden bursts of speed, as these actions burn extra fuel. Consider using cruise control on the highway to maintain a steady speed and avoid unnecessary acceleration.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. It’s a simple task that can make a noticeable difference over time.

Minimize unnecessary weight. Carrying extra cargo adds to the vehicle’s load, forcing the engine to work harder and consume more fuel. Remove any items from the vehicle that you don’t need, especially heavy objects. A cleaner, lighter vehicle is a more efficient vehicle.

Consider engaging the Yukon’s Auto Stop/Start feature. While it may be slightly jarring at first, this system shuts off the engine when you come to a complete stop, such as at a traffic light. This prevents fuel from being wasted while idling, potentially adding up to noticeable savings over time.

Plan your trips efficiently. Combine errands into a single trip to minimize the number of cold starts. Cold starts are particularly fuel-intensive, as the engine needs to warm up to optimal operating temperature. By grouping your errands together, you can reduce the number of cold starts and improve your overall fuel economy.
