The 2024 Jeep Grand Cherokee L 4WD with the 5.7L V8 gets an EPA-estimated 17 MPG combined. It’s not the most fuel-efficient SUV, but it’s built for a specific need: space, capability, and potentially the towing capacity that only a traditional V8 SUV can offer. The hybrid 4xe exists for maximum GRAND MPG across all years for those who prioritize fuel efficiency. The V8 remains an option for a reason.

City and highway performance

EPA estimates of 14 MPG in the city and 22 MPG on the highway illustrate the fuel usage. City driving, with its constant stop-and-go, is where the Grand Cherokee L V8 struggles. The engine size and the vehicle’s weight require more fuel to accelerate from a stop. On the open road, the 8-speed automatic transmission helps keep the engine at optimal RPMs, resulting in a more acceptable 22 MPG. However, even at that highway figure, owners shouldn’t expect small-car fuel economy on long trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Jeep Grand Cherokee L 4WD 5.7L at $3,100. This assumes 15,000 miles per year and national average fuel prices. Buyers should consider this carefully, as gas price fluctuations and individual driving habits can significantly change the actual cost. More than 15,000 miles or a spike in fuel prices will increase your costs at the pump. Less time in traffic should result in a slightly lower fuel bill.

Real-world expectations

EPA estimates are a starting point, but real-world MPG changes. Aggressive driving, heavier loads, towing, and tire pressure all affect fuel consumption. Owners who frequently use the Grand Cherokee L for its intended purpose, hauling people and gear or towing trailers, will likely see numbers closer to the city MPG, or even lower. Those who mainly use it for highway driving may see slightly higher figures, but exceeding 22 MPG will likely require efficient driving habits. Wind resistance is high with this vehicle, so driving above 70 mph impacts fuel economy.

How it compares

Compared to other SUVs, the 2024 Jeep Grand Cherokee L 4WD 5.7L uses more fuel. The Ford Explorer with the 2.3L EcoBoost engine gets around 24 MPG combined, while the V6 version gets closer to 21 MPG. A Toyota Highlander, known for efficiency, gets about 24 MPG combined with its V6 engine. Even the Chevrolet Tahoe, a larger SUV, can get around 17 MPG combined with its 5.3L V8, matching the Grand Cherokee L’s rating despite its size. This shows that the Jeep’s blend of capability and performance has a fuel cost. More efficient options are available for buyers who prioritize fuel economy. Buyers who need a traditional V8 engine can compare all Jeep fuel economy data.

Tips to maximize efficiency

Gentle acceleration minimizes fuel consumption with the 5.7L V8. Avoid pressing hard on the gas pedal, especially when starting from a stop. Gradual acceleration lets the engine operate more efficiently, preventing it from using excess fuel. Let the V8’s torque do the work.

Proper tire inflation is critical. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Check your tires often and inflate them to the recommended pressure on the door jamb.

Reduce unnecessary weight. Extra cargo adds to the vehicle’s weight, directly impacting fuel economy. Remove anything unnecessary, especially heavy or bulky items. Avoid driving with a loaded roof rack if you can store the luggage inside the vehicle.

When possible, use cruise control on the highway. Cruise control keeps a consistent speed, preventing unnecessary acceleration and deceleration. This optimizes fuel efficiency, especially on long highway drives. Be mindful of hills, as cruise control can hurt economy on hilly routes.
