17 MPG combined is what owners of the 2016 Jeep Grand Cherokee 4WD with the 5.7L Hemi V8 actually get. While that number might seem low, understanding who buys this particular Grand Cherokee and why is important. This isn’t the choice if you want to save gas while commuting every day; it’s the selection made by those who prioritize the instant power and confident towing capacity that the Hemi delivers, accepting the fuel economy penalty.

City and highway performance

The EPA estimates for the 2016 Grand Cherokee 4WD 5.7L break down to 14 MPG in the city and 22 MPG on the highway. The city figure reflects the engine’s thirst for fuel during stop-and-go driving, where the vehicle is constantly accelerating from a standstill. The highway number, while better, is still not stellar, partially because the Grand Cherokee’s substantial weight and aerodynamic profile require more energy to maintain higher speeds. The 8-speed automatic transmission helps to keep the engine in its most efficient range, but there are limits when battling physics.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 Jeep Grand Cherokee 4WD 5.7L is $3,100. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Remember that this is just an estimate. Your actual fuel costs will vary depending on your driving habits, where you live (fuel prices can vary significantly by state), and how often you use the vehicle’s four-wheel-drive system.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy for the 2016 Grand Cherokee 5.7L can change depending on the driver. Aggressive acceleration, frequent towing, and consistent off-road use will all hurt fuel efficiency. In contrast, a more relaxed driving style, sticking to paved roads, and proper vehicle maintenance can help you get numbers closer to the EPA estimates. Many owners average slightly lower than the combined 17 MPG, particularly if their driving is primarily city-based. Towing, in particular, will have a dramatic impact, often dropping fuel economy into the single digits. Don’t expect hybrid-like numbers, but do expect consistent capability.

How it compares

In the mid-size SUV segment, the 2016 Grand Cherokee 4WD 5.7L’s fuel economy is toward the lower end. For example, the V6-powered Toyota 4Runner, another body-on-frame 4WD SUV aimed at off-road enthusiasts, achieves a slightly better 18 MPG combined. A similarly equipped Ford Explorer with its 3.5L V6 manages around 20 MPG combined. Even within the Grand Cherokee lineup, choosing the 3.6L V6 significantly improves fuel economy; the 4WD V6 model achieves a combined rating of 21 MPG. Buyers wanting to save gas might cross-shop the GRAND MPG across all years and explore more fuel-conscious SUV options, but those seeking V8 power and reliable towing won’t find many direct competitors. It is also worth reviewing all Jeep fuel economy data to see how new models stack up.

Tips to maximize efficiency

One way to improve fuel economy is to drive smoothly and avoid rapid acceleration and braking. The Hemi is responsive, but gentle throttle inputs allow the engine to operate more efficiently, especially in city driving. Anticipate traffic flow and maintain a steady speed whenever possible to minimize unnecessary fuel consumption.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and ensure it matches the manufacturer’s recommended level, which can be found on the driver’s side doorjamb or in the owner’s manual.

Reduce unnecessary weight. Extra cargo in the vehicle adds to the overall weight, decreasing fuel efficiency. Remove any items you don’t need, especially heavy objects. This principle is even more important when heading off-road, with recovery gear and other equipment adding weight.

Consider your driving mode. Some Grand Cherokee models offer selectable drive modes that can optimize fuel efficiency. Experiment with “Eco” or “Auto” modes, if available, which may adjust engine and transmission settings to prioritize fuel conservation. When off-roading, engage 4WD only when necessary.

Regular maintenance is important for fuel economy. Ensure your engine is properly tuned, and that you replace air filters and spark plugs per the manufacturer’s recommended intervals. A well-maintained engine runs more efficiently and delivers better fuel economy.
