The 2023 Jeep Grand Cherokee 4WD with the 5.7L V8 engine achieves 17 MPG combined, a figure that won’t win any fuel-sipping awards, but one that’s likely a non-issue for the buyer already sold on this particular Grand Cherokee’s strengths. This vehicle is chosen for its reliable towing capacity, its off-road capability, and the satisfying rumble of a naturally aspirated V8. Buyers who prioritize these attributes understand that efficiency is less important.

City and highway performance

The EPA estimates peg city driving at 14 MPG and highway cruising at 22 MPG. The considerable disparity in city versus highway MPG reflects the engine’s thirst for fuel in stop-and-go situations. The eight-speed automatic transmission does its best to optimize fuel use, but the V8’s displacement means it needs a steady flow of fuel to operate. Out on the open road, the Grand Cherokee fares better, with the transmission able to settle into higher gears and the engine working less hard to maintain speed. Expect that 22 MPG to drop significantly, however, when towing or carrying a heavy load.

Annual fuel cost

The EPA calculates the annual fuel cost for this Grand Cherokee configuration at $3,100. This figure assumes 15,000 miles of driving per year, with a calculated percentage of city and highway miles, using national average fuel prices. Note that individual driving habits and local fuel costs can significantly alter this number. If you’re primarily driving in dense urban areas with high fuel costs, your annual expenditure could easily exceed this estimate. Those with longer commutes on less congested highways may see slightly lower fuel bills.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often deviates. Factors such as aggressive driving, tire pressure, the use of accessories like air conditioning, and even weather conditions can affect the MPG you actually achieve. It’s not uncommon for owners to report figures slightly below the EPA estimates, especially during periods of extreme weather or when frequently engaging the four-wheel-drive system. Drivers who prioritize fuel efficiency may occasionally meet or even slightly exceed the EPA’s highway rating.

How it compares

Compared to other SUVs in its class, the 2023 Grand Cherokee 4WD 5.7L V8 is towards the lower end of the fuel economy spectrum. A similarly equipped Ford Explorer with the 3.0L EcoBoost V6, for example, manages around 20 MPG combined. A Toyota 4Runner posts around 17 MPG combined with its V6, similar to the Grand Cherokee’s V8, but with significantly less horsepower and torque, although it is arguably less refined. Even within the Grand Cherokee lineup, opting for the 3.6L V6 nets a significant improvement in fuel economy, with the 4×4 version achieving around 21 MPG combined. The point of this 5.7L V8 is performance; its buyers are less concerned with MPG at the pump.

Tips to maximize efficiency

This powertrain isn’t exactly known for its fuel-sipping nature, but you can still take steps to improve its overall economy. Avoid aggressive acceleration and braking. The V8’s ample torque can be tempting to unleash, but a gentle foot on the accelerator will make a noticeable difference to your fuel consumption. Anticipate traffic flow to maintain a steady speed and minimize unnecessary stops and starts.

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, following the manufacturer’s recommendations listed on the doorjamb. A simple tire pressure gauge can save you money and extend the life of your tires.

Minimize excessive idling. Modern engines are designed to be more efficient when running consistently than when idling for extended periods. If you anticipate being stationary for more than a minute, consider turning off the engine. This is particularly relevant in stop-and-go traffic or at long traffic lights.

Properly maintain your vehicle. Regular maintenance, including oil changes, air filter replacements, and spark plug inspections, ensures that your engine is running at its peak efficiency. A well-maintained engine consumes fuel more efficiently than one that is neglected. Consult your owner’s manual for recommended service intervals.

Consider different models. If fuel economy is your primary concern, you might consider the 4xe plug-in hybrid version of the Grand Cherokee. Keep in mind that selecting the 4WD 5.7L V8 signifies a specific performance priority versus fuel efficiency metrics.
