21 MPG combined isn’t going to win any fuel economy awards, but that’s hardly the point of the 2020 Jeep Wrangler Unlimited 4WD with the 2.0L turbocharged four-cylinder. Its loyal owners aren’t typically cross-shopping with Priuses; they’re buying a Wrangler for its unparalleled off-road capability, open-air experience, and unique personality. Fuel efficiency is a consideration, of course, but it usually ranks far below these other attributes.

City and highway performance

The EPA estimates the 2020 Wrangler Unlimited 4WD with the 2.0L turbo will achieve 21 MPG in the city and 22 MPG on the highway. These numbers are surprisingly consistent, reflecting the engine’s broad torque curve and the smooth-shifting 8-speed automatic transmission. The turbocharger provides ample low-end power, reducing the need to excessively rev the engine in urban environments. On the highway, the aerodynamic compromises inherent in the Wrangler’s design become more apparent, but the tall gearing of the 8-speed helps to keep the engine humming along at a reasonable RPM. Opting for larger tires or adding aftermarket accessories can negatively impact these figures.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Jeep Wrangler Unlimited 4WD 2.0L at $2,100. This figure is based on driving 15,000 miles per year, with a specific percentage of those miles driven in the city versus on the highway, and using the national average fuel price at the time of calculation. Individual fuel costs will vary based on driving habits and local fuel prices, naturally, but $2,100 provides a useful benchmark for comparison.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy will vary. Drivers who frequently engage in off-roading, spend more time battling city traffic, or have a heavy foot can expect to see MPG numbers lower than the EPA estimates. Conversely, those who primarily use the Wrangler for highway cruising and practice fuel-efficient driving techniques might achieve slightly better results. The Wrangler’s upright windshield and boxy shape create considerable aerodynamic drag, which becomes even more pronounced as speeds increase. Expect the range to drop significantly on windy days or when driving at high speeds. Owners report a wider spread than you may expect from a vehicle with a 21 MPG rating. Some see as high as 24 MPG on pure highway trips, while others struggle to reach 18 MPG in mixed driving.

How it compares

Compared to other body-on-frame SUVs with four-wheel drive, the 2020 Wrangler Unlimited 2.0L fairs reasonably well. A comparable Toyota 4Runner, for example, typically achieves around 17 MPG combined. Even smaller crossovers with all-wheel drive often struggle to match the Wrangler’s numbers. A Subaru Forester, although significantly more fuel-efficient at an EPA-rated 29 MPG combined, doesn’t offer the Wrangler’s off-road prowess or removable top and doors. For those prioritizing lower fuel costs, the Wrangler 4xe plug-in hybrid offers an alternative within the Wrangler lineup, achieving significantly better MPG in hybrid mode.

Tips to maximize efficiency

Maintaining proper tire inflation is critical for maximizing fuel economy. The Wrangler often comes equipped with off-road tires, which can have higher rolling resistance than standard passenger car tires. Check the sticker on the driver’s side doorjamb for the recommended tire pressure and ensure your tires are properly inflated.

Avoid aggressive acceleration and braking. The 2.0L turbo engine delivers plenty of torque, so there’s no need to floor the accelerator pedal unless absolutely necessary. Smooth and gradual inputs will help to conserve fuel.

Consider removing unnecessary weight. The Wrangler is already a heavy vehicle, so carrying extra gear or equipment will further reduce fuel economy. Remove any items you don’t need on a regular basis to lighten the load.

Be mindful of aftermarket accessories. Adding a roof rack, larger tires, or a lift kit can significantly impact the Wrangler’s aerodynamic profile and increase rolling resistance. Choose accessories carefully and prioritize those that minimize the impact on fuel economy. For all Jeep fuel economy data, browse through the brand’s complete lineup.
