24 MPG combined is respectable for the 2016 Jeep Grand Cherokee 4WD with the 3.0L diesel engine, but no one is buying this configuration for maximum fuel savings. They’re buying it for Jeep’s off-road capability, comfortable everyday usability, and the torque-rich delivery of the diesel powerplant. The MPG is a bonus, a means to an end, not the primary objective.

City and highway performance

The EPA estimates for this model year and powertrain configuration peg city driving at 21 MPG and highway cruising at 28 MPG. The city figure reflects urban environments, where the Grand Cherokee’s weight and four-wheel-drive system demand more fuel to get moving. The highway number shows the engine’s efficiency when cruising steadily. The eight-speed automatic transmission plays an important role here, keeping the engine in its optimal power band at higher speeds. Drivers who spend the majority of their time on the open road will see numbers closer to that 28 MPG mark, while those primarily navigating city streets should expect results closer to 21 MPG. Observe the GRAND MPG across all years.

Annual fuel cost

The EPA calculates the annual fuel cost for this 2016 Grand Cherokee 4WD 3.0L diesel at $2,300. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving, and assumes national average fuel prices. It provides a benchmark for comparing the fuel expenses of different vehicles. Your actual fuel costs will vary based on your driving habits, the specific conditions in your area, and fluctuations in fuel prices. Drivers who use the diesel’s torque for frequent towing or off-roading are likely to exceed that $2,300 figure.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy often differs. Factors like aggressive driving, carrying heavy loads, tire pressure, and weather conditions can impact the numbers you see on your dashboard. Owner reports and independent testing suggest figures within 1-2 MPG of the EPA estimates are reasonable, though deviations are possible.

Pay attention to your driving style. Smooth acceleration and consistent speeds are key to achieving the best possible fuel economy. Regular maintenance, including timely oil changes and air filter replacements, is also critical for maintaining optimal engine efficiency.

How it compares

The 2016 Grand Cherokee’s diesel fuel economy pits it against interesting competitors. A gasoline-powered 2016 Toyota 4Runner, a popular alternative for off-road enthusiasts, struggles to achieve even 20 MPG combined. A comparable gasoline-powered Grand Cherokee with the V6 manages around 19-20 MPG combined. The diesel’s advantage is clear when considering vehicles like the BMW X5 xDrive35d, which offers similar luxury and performance with a comparable diesel engine but, in 2016 models, offers marginally better fuel economy, around 25 MPG combined. The BMW commands a higher price and doesn’t always match the Jeep’s off-road capability. The differences matter to buyers facing specific needs.

A buyer prioritizing luxury over off-road capability may lean towards the BMW. This helps you determine whether to check all Jeep fuel economy data.

Tips to maximize efficiency

Use the diesel engine’s strong low-end torque. Accelerate smoothly and avoid unnecessary hard acceleration. The diesel delivers peak torque at relatively low RPMs, meaning you don’t need to rev the engine high to get the vehicle moving.

Monitor your tire pressure. Keeping your tires properly inflated reduces rolling resistance, which directly improves fuel economy. Check your tire pressure regularly, especially during temperature changes, and maintain the recommended pressure listed on the sticker inside your driver’s side door.

Use cruise control on the highway whenever possible. Maintaining a constant speed minimizes unnecessary acceleration and deceleration, leading to more consistent and efficient fuel consumption. Cruise control may not be ideal in hilly terrain, where the transmission might frequently downshift to maintain speed.

Avoid excessive idling. If you’re stopped for more than a minute, turn off the engine. Modern vehicles, including the Grand Cherokee, are designed to restart quickly and efficiently, and idling consumes fuel.

Consider using lighter wheels and tires when replacement time comes. While maintaining the integrity required for off-road use is important if that’s part of your intentions, reducing unsprung weight can slightly improve fuel economy, especially in city driving. Consult with a tire specialist to choose options that balance performance and efficiency.
