Eco Mode represents an important advancement in fuel-saving technology for Jeep Wrangler models. This innovative system intelligently adjusts engine parameters and transmission mapping to optimize efficiency.
When enabled, drivers can expect enhanced mileage – allowing their rugged and capable Wrangler to sip fuel rather than guzzle it. This offers compelling benefits, from saving money at the gas pump to treading lighter on the planet by reducing emissions.
Let’s take an in-depth look at what exactly Eco Mode does and why it matters:
The Mechanics: What Happens Inside Your Jeep’s Engine and Drivetrain
Activating Eco Mode initiates a series of mechanical adjustments under the hood:
Engine Modifications
Eco Mode alters the air-to-fuel ratio, allowing more air into the intake manifold while precisely governing fuel input. This leaner combustion equation extracts more energy from less gasoline for improved economy.
Additionally, the engine control module can deactivate up to half of the cylinders when coasting or maintaining a steady, light load. This cylinder deactivation ceases operation in cylinders that aren’t necessary, avoiding wasted fuel.
Together, these interventions reduce energy consumption through smarter mechanical operations.
Transmission Changes
The transmission also shifts strategy within the drivetrain, choosing higher gears sooner and avoiding frequent downshifts. This keeps engine RPMs low to optimize efficiency.
While acceleration performance is lowered slightly, there is no meaningful loss of Jeep’s legendary off-road capability or ability to power through tough conditions. The transmission instantly recognizes increased throttle input and taps into full engine power.

Locating the Switch and Identifying You’re in Eco Mode
Drivers activate Eco Mode differently depending on Wrangler model year:
2014-2018 Jeep Wranglers
These models featured a dedicated “ECO” button positioned on the center dash panel. Depressing it toggles the mode on and off.
2019+ Jeep Wranglers
Newer Wranglers have the Eco Mode switch integrated into the drive mode selector. Simply turn the rotary control to “Eco” to enable enhanced efficiency.
Eco Mode Confirmation
Across all variants, an Eco Mode light in the instrument cluster illuminates when efficiency measures take effect. This handy indicator lets drivers know the mode is active.
Additionally, revving the engine or mashing the accelerator temporarily suspends Eco Mode. This guarantees full power on demand for safe highway merging or tricky off-road conditions.
If you don’t notice an indicator or feel a difference in performance, double check your mode activation. When properly engaged, Eco Mode alters mechanical operations to conserve fuel.
Calculating Eco Mode’s Impact: Expected Fuel Savings in Action
So how much does Eco Mode actually help? Testing reveals:
- Up to 15% fuel economy improvement in city driving
- Around 10% boost in steady highway mileage
For example, if a 2018 Jeep Wrangler returns:
- 16 mpg city / 21 mpg highway
The owner could expect Eco Mode to deliver:
- 18 mpg city / 23 mpg highway
This bump comes from modified engine and transmission settings without diminishing drivability. Of course, factors like terrain, payload, and driving style still impact efficiency. But properly utilizing Eco Mode nets meaningful savings.
Over 5,000 miles of mixed-usage driving, the increase translates into around 25 fewer gallons burned annually . At $4 per gallon, that’s $100 in yearly fuel savings by using Eco Mode smartly. Consider it a nice bonus – less trips to the pump and less environmental impact!
Eco Driving Tips: Optimizing Your Eco Mode Experience
While Eco Mode automatically adjusts mechanical factors, smarter driving habits multiply its effectiveness:
- Maintain steady speeds, avoiding jackrabbit starts and hard stops
- Plan routes to minimize congestion and long idles when possible
- Remove unnecessary cargo weight
- Check tire pressures monthly
- low tires waste fuel
- Use cruise control on flat highway stretches
- Limit blasting the A/C when able
Pairing Eco Mode with conservation-focused driving techniques can further extend range and reduce fill ups. Think smoothly rather than aggressively and keep your Jeep as light as conditions allow.
The Trade-Off: Understanding Eco Mode’s Impact on Performance
Eco Mode isn’t magic – altering engine and transmission priorities has some performance trade-offs:
Throttle Sensitivity
Accelerator input feels slightly less responsive. This prevents wasteful revving and rapid acceleration out of gear. Eco Mode eases into speed boosts rather than reacting sharply.
Gear Hunting
The transmission hangs onto higher gears more often without downshifting readily. This keeps RPMs low but can occasionally impact responsiveness.
Power Reduction
Expect around 10-15% less horsepower and torque while Eco Mode is active. This may be noticeable when climbing hills or trailblazing off-road.
However, Eco Mode instantly suspends when drivers floor the throttle. So full capabilities arrive when heavy power is demanded.
In essence, Eco Mode shifts the priority spectrum towards efficiency over performance. But it retains crucial Jeep attributes around towing capacity, four-wheel drive traction, and ultimately – fun!
Eco Mode’s Verdict: An Important Asset for Jeep Wrangler Owners
- Saves money at the pump – paying less in fuel costs
- Reduces environmental impact through cut emissions
- Preserves engine life by limiting RPMs
- Retains essential Jeep capability when it matters
This innovative drive mode gives owners the best of both worlds – unlocking fuel efficiency without compromising iconic Jeep qualities. Eco Mode is recommended for:
- Daily commuting
- Highway road trips
- Stop-and-go traffic
It’s not essential for extreme rock crawling or desert racing situations where throttle precision reigns supreme.
Overall, Eco Mode is an invaluable asset for the Jeep Wrangler range. This smart efficiency tool empowers drivers to embrace savings and tread lighter – all while retaining the freedom, fun, and function Jeep is known for. Turn it on and save some green!
