18 MPG combined won’t win any awards and won’t impress anyone accustomed to crossovers or sedans. But for the 2016 Jeep Wrangler Unlimited 4WD with the 3.6L V6, it’s an accepted part of the deal. This isn’t a vehicle designed for maximum fuel efficiency, it’s a purpose-built machine for off-road exploration and open-air adventure. The Wrangler Unlimited buyer prioritizes capability, customization, and a unique driving experience far above saving a few dollars at the pump.

City and highway performance

The EPA estimates the 2016 Jeep Wrangler Unlimited 4WD gets 16 MPG in the city and 20 MPG on the highway. These figures reflect the Wrangler’s aerodynamic profile (or lack thereof), its hefty weight, and the inefficiencies inherent in a solid front axle and four-wheel-drive system. The 3.6L V6 provides adequate power, but the older 5-speed automatic transmission works hard to keep the Wrangler moving, especially at highway speeds, further impacting fuel consumption. The city MPG suffers due to frequent stop-and-go traffic and the Wrangler’s need for more throttle input to accelerate. The highway figure approaches 20 MPG only when driven conservatively and at steady speeds, a rare occurrence for most Wrangler owners eager to reach their next off-road destination.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Jeep Wrangler Unlimited 4WD at $2,450. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of testing. Keep in mind this is merely an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and the current price of gasoline in your area. Owners who primarily drive in the city, engage in frequent off-roading, or have a lead foot will likely exceed this $2,450 estimate. It’s a significant expense, and one that prospective buyers should carefully consider before committing to Wrangler ownership.

Real-world expectations

While the EPA figures provide a baseline, real-world fuel economy for the 2016 Jeep Wrangler Unlimited 4WD tends to be a bit lower, especially for owners who have modified their vehicles. Larger tires, lift kits, and added accessories like heavy bumpers and winches can all negatively impact fuel efficiency. Driving style also plays a significant role. Those who frequently accelerate aggressively or drive at high speeds will see a noticeable drop in MPG. Owners who prioritize fuel economy can achieve numbers close to the EPA estimates by driving conservatively, maintaining proper tire inflation, and avoiding unnecessary weight. However, for most Wrangler owners, enjoying the vehicle’s capabilities outweighs the desire for optimal fuel efficiency, so lower MPG numbers are simply accepted.

How it compares

Compared to other SUVs, the 2016 Jeep Wrangler Unlimited’s fuel economy lags considerably. For example, a contemporary Toyota 4Runner 4WD, while also body-on-frame and off-road capable, manages around 19 MPG combined with its V6 engine. A Honda Pilot boasts superior fuel efficiency, achieving around 22 MPG combined in its AWD configuration, though it sacrifices off-road prowess. Even the larger Ford Explorer with its available V6 can achieve 20 MPG combined in 4WD guise. However, these vehicles don’t offer the same open-air experience or the rock-crawling abilities of the Wrangler. The buyer choosing the Wrangler makes a conscious trade-off, prioritizing adventure and customization options that simply aren’t available in more fuel-efficient SUVs.

Tips to maximize efficiency

Maintaining proper tire inflation is critical. The Wrangler’s large, aggressive tires are prone to rolling resistance, which directly impacts fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications, which can be found on a sticker inside the driver’s side doorjamb.

Avoid unnecessary weight. The more weight the Wrangler carries, the harder the engine has to work, leading to decreased fuel efficiency. Remove any unnecessary items from the vehicle, such as tools, equipment, or extra gear that isn’t needed for your current drive. Every pound counts.

Anticipate traffic and drive smoothly. Aggressive driving habits, such as rapid acceleration and hard braking, can significantly reduce fuel economy. Anticipate traffic flow and maintain a consistent speed whenever possible. Gentle acceleration and smooth braking will help conserve fuel.

Consider the impact of modifications. While modifications like lift kits and larger tires can enhance the Wrangler’s off-road capabilities, they also negatively impact fuel economy. Be mindful of the added weight and rolling resistance associated with these modifications and adjust your driving habits accordingly.

Regular maintenance is key. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including regular oil changes, air filter replacements, and spark plug inspections. Addressing any mechanical issues promptly can help optimize fuel economy.
