2026 Jeep® Gladiator Fuel Economy Specs

Under the hood of every 2026 Jeep® Gladiator truck sits a robust 3.6L Pentastar® V6 engine engineered for dependable performance across rough terrain and highway miles alike. Standard Jeep® Gladiator mpg ratings for city and highway driving include:

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

Equipped with standard four-wheel drive and built for high-ground-clearance adventuring, this midsize pickup keeps you moving without constant fill-ups. Every Jeep® Gladiator vehicle features a generous 22-gallon fuel tank, extending your driving range so you can spend less time at local gas stations and more time conquering Idaho trails.

Engineered Efficiency Features

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

• Engine Stop/Start (ESS) Technology: Automatically shuts down the 3.6L V6 engine when coming to a complete stop at traffic lights, restarting seamlessly when you release the brake pedal to conserve fuel.
• 8-Speed Automatic Transmission: Intelligently adapts shift points based on road conditions and vehicle load to optimize efficiency during daily commutes or heavy hauling.
• Adaptive Cruise Control with Stop: Maintains set highway pacing across Canyon County, adjusting speed automatically to deliver a smoother, more efficient driving experience.
