13 MPG combined. The 2021 Grand Cherokee Trackhawk 4WD, with its supercharged 6.2L V8, isn’t designed for fuel efficiency. This machine’s purpose is unholy acceleration and a supercharger whine that overpowers other cars while you’re driving to the store. Its buyers prioritize performance, so fuel economy is a secondary consideration compared to the thrill this SUV provides. They’re buying a fast quarter-mile, not fuel efficiency.

City and highway performance

The Trackhawk’s EPA estimates show a big difference between city and highway MPG. The city MPG is a dismal 11. Expect this gas mileage, because stop-and-go traffic, combined with the engine’s high fuel demand during acceleration, uses a lot of gas. However, on the highway, the MPG increases to 17. Resisting the urge to accelerate will be a constant battle, and your actual fuel consumption will vary.

Annual fuel cost

The EPA estimates the 2021 Jeep Grand Cherokee Trackhawk 4WD’s annual fuel cost at $4,450. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway, assuming the use of gasoline priced at the national average. While these assumptions provide a baseline, your individual fuel costs may vary based on driving habits and local fuel prices. If you frequently use the Trackhawk’s performance, expect that $4,450 figure to increase considerably. For those concerned, you can always find all Jeep fuel economy data on our hub.

Real-world expectations

Drivers find it challenging to match the EPA’s 17 MPG highway estimate, because using the supercharged V8’s power is so tempting. Expect a realistic combined MPG closer to 10-12 in daily driving. Aggressive drivers may even get less MPG, making frequent gas station visits a regular part of Trackhawk ownership. Consider your driving style before buying this vehicle; you’ll be visiting the gas station often.

How it compares

The Trackhawk’s position in the market makes its alternatives clear. The BMW X5 M manages 15 MPG combined, despite a similar intention. The Mercedes-AMG GLE 63 S Coupe also gets a slightly better 15 MPG combined. Even the less powerful Jeep Grand Cherokee SRT achieves 15 MPG combined. These differences demonstrate the Trackhawk’s focus on raw power. While other performance SUVs acknowledge fuel efficiency, the Trackhawk does not.

Tips to maximize efficiency

The Trackhawk’s gas mileage is low, but you can reduce your fuel costs.

Resist the urge to accelerate hard from every stop. Accelerating gradually, even in a powerful vehicle, will reduce fuel consumption. Control the throttle, and your fuel tank will last longer.

Maintain a steady speed on the highway. Fluctuating speeds waste fuel. Use cruise control on long trips, when possible, to reduce unnecessary acceleration and deceleration.

Ensure your tires are properly inflated. Under-inflated tires increase rolling resistance, making the engine work harder. Check your tire pressure regularly and inflate to the level specified on the door jamb.

Reduce excess weight, because this car is heavy. Carrying excess items in the cargo area reduces fuel economy. Remove unnecessary items from the vehicle to minimize the load.
