21 MPG combined is an acceptable, if not stellar, figure for the 2016 Jeep Grand Cherokee 4WD with the 3.6L V6. No one buys a Grand Cherokee *primarily* for its fuel efficiency. People buy a Grand Cherokee for its blend of rugged capability, on-road comfort, and elevated image. Acceptable fuel economy is simply the price of entry, balanced against its extensive skillset.

City and highway performance

The EPA estimates for the 2016 Grand Cherokee 4×4 V6 are 18 MPG for city driving and 25 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the Grand Cherokee’s weight and full-time four-wheel-drive system take their toll. However, the eight-speed automatic transmission helps optimize fuel economy on the open road, allowing the engine to cruise at lower RPMs. The difference between city and highway MPG underscores the advantage of highway driving in minimizing fuel consumption with this powertrain.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 Jeep Grand Cherokee 4WD 3.6L V6 is $2,100. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that fluctuations in gas prices will directly impact this number. Those who drive more than 15,000 miles annually will spend more on fuel, while those who drive less will spend less. It’s a useful benchmark for budgeting, but your individual results will vary.

Real-world expectations

While the EPA estimates provide a standardized comparison point, real-world fuel economy often differs. Factors like driving style, terrain, weather conditions, and vehicle maintenance all play a role. Aggressive acceleration and frequent hard braking will significantly decrease fuel economy. Uphill driving and towing will have a similar effect.

Keeping tires properly inflated and adhering to the manufacturer’s recommended maintenance schedule will help maintain optimal fuel efficiency. Don’t be surprised if your observed MPG varies by a few miles per gallon from the EPA estimates, consider the official numbers a best-case scenario under ideal conditions.

How it compares

The 2016 Jeep Grand Cherokee’s fuel economy is generally in line with other mid-size SUVs that offer comparable levels of off-road capability and interior space. Consider the Toyota 4Runner 4×4, which offers similar off-road prowess to the Grand Cherokee, yet only manages 18 MPG combined. The Ford Explorer 4WD with the 3.5L V6, a more road-focused SUV, achieves 19 MPG combined, still less than the Grand Cherokee. A more efficient option might be the Nissan Murano, which delivers around 24 MPG combined in its front-wheel-drive configuration.

However, the Murano is noticeably less capable off-road and lacks the Grand Cherokee’s rugged image. This comparison highlights the tradeoffs buyers make. Those prioritizing all-terrain capability and a strong SUV often accept a slight compromise in fuel economy. You can also find all Jeep fuel economy data on our site for a broader analysis.

Tips to maximize efficiency

Use smooth acceleration and avoid aggressive driving. The Grand Cherokee’s V6 has ample power, but rapid acceleration burns fuel unnecessarily. Anticipate traffic flow and maintain a steady pace to minimize fuel consumption.

Ensure your tires are inflated to the recommended pressure, which is typically found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, reducing fuel economy. Check your tire pressure regularly, especially during temperature changes.

Reduce unnecessary weight in the vehicle. Extra cargo adds to the vehicle’s overall weight, requiring the engine to work harder. Remove any items you don’t need, especially heavy objects stored in the cargo area.

Consider your drive mode. If your Grand Cherokee is equipped with selectable terrain modes, use the “Auto” or “Eco” mode for everyday driving on pavement. These modes optimize fuel efficiency by adjusting throttle response and transmission shift points.

Proper vehicle maintenance is important. Regular oil changes, air filter replacements, and spark plug maintenance are essential for optimal engine performance and fuel efficiency. Adhering to the manufacturer’s recommended maintenance schedule will help keep your Grand Cherokee running efficiently.
