22 MPG combined defines the 2025 Jeep Grand Cherokee 4WD with the 3.6L Pentastar V6, a steady figure for a mid-size SUV that blends capability with everyday usability. This isn’t a headline-grabbing efficiency number, nor is it meant to be. Instead, it’s a commitment to a proven powertrain in a vehicle designed for families who value strong construction, genuine all-weather peace of mind, and the ability to tow. Those who opt for the venerable Pentastar in their Grand Cherokee understand they’re choosing a workhorse, a versatile companion for everything from school runs to mountain trails, and they accept its fuel economy as an appropriate trade-off for its character and mission. This is the Grand Cherokee for the vast majority, the one that embodies the core Jeep promise without straying into the territory of HEMI power or 4xe electrification.

City and highway performance

The EPA’s numbers show the 2025 Grand Cherokee 4WD 3.6L delivers 19 MPG in the city and 26 MPG on the highway. The city figure, at 19 MPG, is expected. A nearly 4,700-pound SUV with a standard 4WD system, regardless of its relatively modern 8-speed automatic, will naturally see its efficiency dip in stop-and-go conditions. This is the reality of moving that much mass from a standstill repeatedly. Drivers often encounter this and understand. The highway performance, however, at 26 MPG, is a commendable showing. On longer cruises, with the 8-speed automatic smoothly managing the revs, the Pentastar V6 finds its stride, allowing the Grand Cherokee to deliver respectable long-haul efficiency. This is particularly relevant for those planning road trips or regular commutes that involve significant highway stretches, making it a comfortable and capable cruiser.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,000 for the 2025 Jeep Grand Cherokee 4WD 3.6L. This figure is a calculated projection based on a standardized methodology. The EPA assumes a total annual mileage of 15,000 miles, distributed roughly 45% city driving and 55% highway driving, mirroring typical American driving patterns. This 15,000-mile figure is then combined with the national average fuel prices to arrive at the $2,000 annual cost. For a prospective buyer, this $2,000 serves as a clear benchmark for expected fuel expenses over a year. While individual driving habits and local fuel prices will cause this number to fluctuate in practice, it provides a crucial, consistent point of comparison when evaluating the Grand Cherokee against alternatives and budgeting for ownership. It’s a transparent, data-driven estimate designed to help consumers understand the ongoing financial commitment of their vehicle choice.

Real-world expectations

In the real world, achieving the EPA’s 22 MPG combined with the 2025 Grand Cherokee 4WD 3.6L is entirely plausible. However, drivers need to understand that their unique driving style and environment play a significant role. Aggressive acceleration, heavy braking, and extended periods of stop-and-go traffic will push the figures closer to the 19 MPG city estimate, or even below it. Conversely, a smooth, measured driving style, anticipating traffic flow, and maximizing coasting can often yield results that meet or even slightly exceed the EPA numbers, particularly on longer highway journeys. Factors like tire pressure, cargo load, and the frequent use of the 4WD system (especially in low range or on particularly challenging terrain) will also impact real-world fuel economy. This vehicle is built for utility and capability; using those capabilities will naturally consume more fuel. Owners know this and accept it as part of the Grand Cherokee experience.

How it compares

When placed against its key rivals, the 2025 Grand Cherokee 4WD 3.6L’s 22 MPG combined holds its own, often representing a practical sweet spot for its segment. Consider the Toyota 4Runner TRD Off-Road, a direct competitor in terms of rugged capability. The 4Runner with its 4.0L V6 manages a less impressive 17 MPG combined (16 city/19 highway), making the Grand Cherokee a clear winner for daily efficiency. Even more mainstream mid-size SUVs can struggle to significantly distance themselves. The Honda Passport, while offering slightly better numbers at 21 MPG combined (19 city/24 highway) for its AWD trim, doesn’t quite match the Grand Cherokee’s inherent towing capacity or its off-road pedigree. The Kia Telluride AWD, a popular choice, achieves 21 MPG combined (19 city/24 highway), again demonstrating that the Grand Cherokee’s figures are competitive, particularly considering its more substantial construction and available all Jeep fuel economy data prowess. This isn’t a class-leading efficiency champion, but for what it offers in utility, capability, and refined driving dynamics, its fuel economy is well-positioned.

Tips to maximize efficiency

Maintain consistent highway speeds and use cruise control whenever possible. The 8-speed automatic is designed to find optimal gears, and steady throttle inputs allow it to operate most efficiently, particularly on flat terrain where aerodynamic drag is the primary resistance.

Ensure your tires are properly inflated to the manufacturer’s recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check them monthly.

Practice smooth acceleration and braking. Rapid take-offs and sudden stops waste fuel. Anticipate traffic and coast to a stop when safe, rather than braking sharply.

Remove unnecessary weight from the vehicle, especially items stored on the roof rack if not in use. Extra weight forces the engine to burn more fuel to maintain speed, impacting both city and highway numbers for GRAND MPG across all years.

Avoid excessive idling. If you’re going to be stopped for more than 30 seconds, it’s generally more fuel-efficient to turn off the engine and restart it when ready to proceed. This is especially true for prolonged waits.
