13 MPG combined. The 2020 Jeep Grand Cherokee Trackhawk isn’t bought for its efficiency. It’s bought for the ferocious supercharged V8 and brutal acceleration. Trackhawk owners prioritize swagger over trips to the gas station. They know exactly what they’re getting into, and 11 MPG city isn’t going to deter them.

City and highway performance

The EPA estimates 11 MPG in the city and 17 MPG on the highway. With 707 horsepower, it takes self-control to resist flooring it. Stop-and-go traffic will punish your fuel economy. The highway figure is more reasonable, assuming you can resist passing everyone. Even then, it’s a far cry from what you’d expect from a more sensible SUV.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Jeep Grand Cherokee Trackhawk is $4,450. This is based on driving 15,000 miles per year and uses national average fuel prices. This is not a thrifty vehicle for commuting. It’s a toy, and you pay a steep price. Premium fuel is recommended, increasing expenses.

Real-world expectations

The EPA figures are a guide, but real-world MPG will vary based on driving style. Aggressive acceleration, frequent short trips, and heavy traffic will depress fuel economy. However, careful highway cruising might allow you to approach, or exceed, the 17 MPG highway estimate. However, anyone expecting to consistently achieve the EPA numbers will likely be disappointed.

How it compares

The Trackhawk’s fuel economy lags behind its Grand Cherokee siblings. The standard V6-powered Grand Cherokee achieves 21 MPG combined. The V8-powered Grand Cherokee SRT manages 15 MPG combined, with less horsepower. Comparing it to other performance SUVs, the BMW X5 M, with its 600 horsepower, gets 15 MPG combined. The Mercedes-AMG GLE 63 S Coupe achieves 15 MPG. These alternatives offer comparable performance, and they project a different image. The Trackhawk projects an American brand of muscle, for those uninterested in European alternatives. For all Jeep fuel economy data, start here.

Tips to maximize efficiency

Smooth and steady acceleration is the most effective way to conserve fuel. Resist the temptation to unleash the supercharger unless necessary. Treat the throttle with respect, and anticipate traffic flow to minimize hard braking.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and maintain the recommended level. This is important given the Trackhawk’s high performance and relatively short tire life.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Idling consumes fuel unnecessarily. The Trackhawk’s reliable starter is designed to handle frequent starts and stops.

Use cruise control on the highway. Maintaining a consistent speed helps optimize fuel economy. Avoid rapid acceleration and deceleration, which wastes fuel. This is beneficial on longer trips where the rewards of consistent throttle input become noticeable.

Reduce weight by removing any unnecessary items. Extra weight increases fuel consumption. While it might seem insignificant, every little bit helps. Consider removing any items you don’t need for daily driving.
