The 2021 Jeep Grand Cherokee 4WD V6 gets 21 MPG combined. No one buys this Grand Cherokee expecting Prius-like efficiency. This particular configuration, equipped with four-wheel drive and the strong 3.6L Pentastar V6, appeals to those who need a blend of everyday practicality and genuine off-pavement capability. Gas mileage expectations are often secondary to the vehicle’s overall mission: hauling families, towing small trailers, and navigating less-than-ideal weather conditions with confidence.

City and highway performance

The EPA estimates put the 2021 Jeep Grand Cherokee 4WD V6 at 18 MPG in the city and 25 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the Grand Cherokee’s weight and four-wheel-drive system take their toll. The highway number, however, is reasonably respectable, thanks in part to the eight-speed automatic transmission that allows the engine to cruise at lower RPMs. Still, aerodynamic drag from the Grand Cherokee’s boxy shape prevents it from achieving truly impressive highway mileage.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2021 Jeep Grand Cherokee 4WD V6 is $2,100. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that fluctuations in gas prices and individual driving habits can significantly affect this number. Those who primarily drive in the city, frequently tow, or have a heavy foot will likely exceed this estimate. Conversely, those who do predominantly highway miles and practice more fuel-conscious driving could potentially see lower costs. Consider this figure a benchmark, not a guarantee.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy often varies. Factors such as driving style, terrain, and load can all impact the Grand Cherokee’s MPG. Aggressive acceleration, frequent braking, and carrying heavy cargo will all decrease fuel efficiency. Owners living in mountainous regions should also anticipate lower mileage due to the increased demands on the engine. Properly inflated tires and regular maintenance are critical to maintaining optimal fuel economy. Many owners report that they closely match the EPA estimates, but some report less. Your mileage will vary!

How it compares

The 2021 Jeep Grand Cherokee 4WD V6 doesn’t lead the pack in fuel economy, but its capabilities set it apart. Consider the Toyota 4Runner, a reliable competitor with genuine off-road prowess. However, the 4Runner’s older five-speed automatic, when configured with four-wheel drive, manages only 17 MPG combined. The Ford Explorer, in its four-wheel-drive configuration with the 2.3L EcoBoost engine, offers a slightly better 23 MPG combined. Those prioritizing fuel economy may be better served by a more modern crossover SUV such as the Honda Passport, which achieves 21 MPG combined with its standard V6 and all-wheel drive.

Exploring a GRAND MPG across all years can provide additional insights.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Grand Cherokee is not a sports car, and sudden bursts of speed or hard braking significantly reduce fuel efficiency. Opt for smooth, gradual acceleration and anticipate traffic stops to minimize braking. Maintaining a consistent speed on the highway is also key.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, ideally every week, and inflate them to the pressure recommended on the doorjamb sticker.

Reduce excess weight. Hauling around unnecessary cargo puts extra strain on the engine and lowers fuel economy. Clear out any items you don’t need from the cargo area and passenger compartment. Even small items can add up and negatively affect MPG.

Minimize idling. Allowing the engine to idle for extended periods consumes fuel without covering any distance. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, saving you fuel in the long run.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, preventing fluctuations in throttle input that can waste fuel. Use cruise control on flat stretches of highway to optimize fuel efficiency. However, be mindful of using it in hilly terrain, where the system may downshift aggressively and reduce MPG.
