21 MPG combined isn’t going to win any awards, but the 2020 Jeep Grand Cherokee 2WD 3.6L V6 isn’t about saving fuel. This configuration is for buyers who value space, comfort, and some ruggedness in a reasonably priced vehicle, while preferring to forgo the cost and complexity of four-wheel drive. These are suburban families, empty nesters, and those who prioritize a roomy interior and smooth ride over ultimate efficiency. They accept the fuel economy because the Grand Cherokee delivers in other critical areas.

City and highway performance

The EPA estimates 19 MPG in the city and 26 MPG on the highway for this two-wheel-drive Grand Cherokee equipped with the 3.6L V6. The numbers show the engine’s performance. The V6 provides enough power for confident merging and passing on the highway, which explains the relatively strong highway MPG. The city MPG, however, reflects the Grand Cherokee’s weight and the stop-and-go nature of urban driving. Expect the auto start/stop system to activate frequently (if equipped) at stop lights, as the vehicle tries to save fuel on city streets.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2020 Jeep Grand Cherokee 2WD 3.6L V6 is approximately $2,100. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, local fuel prices, and the specific conditions in your area. If you drive aggressively and live in an area with high gas prices, expect to pay more. The EPA calculates this figure to help consumers compare vehicles’ operating costs.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. Factors like driving style, tire pressure, and cargo weight can all influence the MPG you achieve. If you frequently haul cargo, expect to see a dip in fuel economy. Gentle acceleration and consistent highway speeds will help you get closer to the EPA estimates, but aggressive driving and heavy traffic will decrease your numbers.

How it compares

The 2020 Jeep Grand Cherokee 2WD 3.6L V6 competes against a wide range of mid-size SUVs. The Toyota 4Runner, with its standard V6 and four-wheel drive, manages only 17 MPG combined, making the Grand Cherokee seem relatively efficient. The Honda Passport, a more modern and car-like SUV, achieves 22 MPG combined with its V6 and standard front-wheel drive. The Passport is better than the Grand Cherokee here, and the Cherokee offers spaciousness and a driving feel that the Passport doesn’t provide. Within the Stellantis family, the Dodge Durango with its V6 and rear-wheel drive, matches the Grand Cherokee’s 21 MPG combined. For buyers considering a more luxurious option, the Lexus RX 350 achieves 23 MPG combined with its V6 and front-wheel drive, a noteworthy improvement compared to the Grand Cherokee. Buyers who want to explore all Jeep fuel economy data should remember that Jeep offers other configurations to meet different needs.

Tips to maximize efficiency

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side door.

Avoid aggressive driving habits. Rapid acceleration and hard braking waste fuel. Drive smoothly and anticipate traffic flow to minimize unnecessary acceleration and deceleration. Using cruise control on the highway can help maintain a consistent speed and improve fuel economy.

Reduce excess weight. Carrying unnecessary weight in your vehicle reduces fuel efficiency. Remove any items from your trunk or cargo area that you don’t need. Even small amounts of weight can add up and impact your MPG.

Consider using the “Eco” mode, if equipped. This mode typically adjusts throttle response and transmission shift points to prioritize fuel economy. While it may slightly reduce performance, it can make a noticeable difference in your MPG, especially in city driving.

Keep up with regular maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements. A neglected engine can experience reduced fuel economy and performance.
