That said, rising gas prices have many Vacherie drivers prioritizing fuel efficiency when purchasing their next truck. So, how many miles per gallon can you expect from the 2026 Gladiator? Find out in this comprehensive Jeep Gladiator gas mileage guide from Southland of Thibodaux.

2026 Jeep Gladiator Fuel Economy

No matter which 2026 Jeep Gladiator trim you choose, you’ll find a robust 3.6L V6 engine under the hood. This standard engine delivers impressive performance on every adventure, but that power comes at the expense of the truck’s efficiency. See the standard Jeep Gladiator mpg ratings for city and highway driving below:

• City: 17 mpg
• Highway: 22 mpg
• Combined: 19 mpg

With its all-terrain design and standard four-wheel drivetrains, it’s no surprise that the Jeep Gladiator isn’t as fuel-efficient as a smaller SUV or compact sedan. That said, drivers won’t have to worry about constant fill-ups. Every Jeep Gladiator comes equipped with a 22-gallon fuel tank, allowing drivers to spend more time conquering the trails and less time at the Napoleanville gas stations. 

2026 Jeep Gladiator: Fuel-Saving Features

To help drivers make the most of every tank, the 2026 Jeep Gladiator offers several fuel-saving features, including:

• Engine Stop/Start (ESS) Technology: The 3.6L V6 engine that powers the Jeep Gladiator comes standard with Engine Stop/Start (ESS) technology. This popular technology monitors your vehicle’s speed and, when you come to a complete stop, turns off the engine to conserve fuel. The engine automatically restarts once the brake pedal is released, providing an uninterrupted driving experience. 
• 8-Speed Automatic 850RE Transmission: The standard automatic transmission on the Jeep Gladiator adapts its shift points based on driving conditions, ensuring you receive optimal efficiency on every drive.
• Adaptive Cruise Control with Stop: Planning a weekend road trip? Consider upgrading to a Jeep Gladiator configuration with Adaptive Cruise Control. Designed to maintain a set speed or distance from vehicles in the lane ahead, the Adaptive Cruise Control with Stop feature provides a smooth and fuel-efficient driving experience.
