21 MPG combined isn’t likely to be a selling point for the 2021 Jeep Grand Cherokee L 2WD 3.6L 6-cyl, but buyers considering this extended-wheelbase SUV aren’t prioritizing Prius-like efficiency. They need three rows of seating, reasonable cargo capacity, and the reassurance of a Jeep badge. Fuel efficiency is a factor, certainly, but it’s balanced against capability and practicality. This particular model is designed for family duties both around town and on the open road, and the fuel economy reflects that compromise.

City and highway performance

The EPA estimates the 2021 Jeep Grand Cherokee L 2WD with the 3.6L V6 will achieve 19 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go driving, and the vehicle’s weight definitely plays a role here. The highway number is more respectable, partly thanks to the smooth-shifting 8-speed automatic transmission which allows the engine to cruise at lower RPMs improving overall fuel economy. Remember that these are EPA estimates, and real-world driving conditions significantly impact fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for this Grand Cherokee L configuration at $2,100. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway. The estimate assumes national average fuel prices. Of course, fuel prices fluctuate, and individual driving habits vary, so your actual fuel costs may differ. But $2,100 provides a reasonable benchmark for budgeting purposes.

Real-world expectations

While the EPA provides a standardized estimate, some owners report slightly lower MPG in real-world conditions, particularly in purely city driving, where 16-18 MPG is more commonly reported. On long highway trips, achieving the EPA’s 26 MPG is possible if you maintain steady speeds and avoid aggressive acceleration.

How it compares

Compared to other three-row SUVs, the 2021 Jeep Grand Cherokee L 2WD’s fuel economy falls somewhere in the middle. The Toyota Highlander with its 3.5L V6 achieves 24 MPG combined, offering a noticeable advantage. The Ford Explorer with the 2.3L EcoBoost engine is closer, reaching 23 MPG combined. The Chevrolet Traverse, another popular choice, mirrors the Grand Cherokee L at 21 MPG combined. Stepping into the realm of luxury SUVs, the Acura MDX achieves 22 MPG combined with its V6 engine. These slight differences matter to buyers who meticulously calculate long-term running costs, and those looking for the most efficient option may prioritize the Highlander or Explorer over the Grand Cherokee L. Compare all Jeep fuel economy data to see how this model stacks up.

Tips to maximize efficiency

The 3.6L V6 is a responsive engine, but avoid aggressive acceleration. Smooth and gradual acceleration will significantly improve fuel economy, particularly in city driving. Anticipate traffic flow and maintain a steady speed whenever possible.

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 manufacturer’s recommended pressure, which can usually be found on a sticker on the driver’s side doorjamb.

Excessive idling consumes fuel. If you’re stopped for more than a minute, turn off the engine. Many newer vehicles have auto start/stop features, but this Grand Cherokee L relies on you to make a conscious decision to avoid idling when possible.

Remove unnecessary weight from the vehicle. The lighter the vehicle, the less fuel it consumes. Take out any items you don’t need, like sporting equipment or extra cargo, to improve MPG. The GRAND MPG across all years can vary depending on trim and options.

Consider using cruise control on the highway. This helps maintain a consistent speed, which optimizes fuel economy. Set the cruise control at a reasonable speed and let the vehicle manage the throttle, rather than constantly adjusting your speed with your foot.
