2026 Jeep® Gladiator MPG and Powertrain Guide
Every 2026 Jeep® Gladiator is built with the same powertrain. That means a 3.6L Pentastar V6, an eight-speed automatic transmission, and standard four-wheel drive. The single-powertrain strategy makes the Gladiator unusually easy to shop. Whichever trim you pick, the engine, the transmission, and the EPA-estimated fuel economy numbers are identical.
What Engine Powers the 2026 Jeep Gladiator?
The 2026 Jeep Gladiator comes standard across all trim levels with a 3.6L Pentastar V6 generating 285 horsepower and 260 lb-ft of torque. Jeep pairs that engine exclusively with an eight-speed automatic transmission. It drives a standard four-wheel drive system. No diesel engine is offered on the 2026 Gladiator lineup. No manual transmission is available either. These figures come from Jeep’s 2026 Gladiator model-year announcement.
The 3.6L Pentastar V6 is built for highway commutes and off-road trails alike. It delivers throttle response across a broad RPM range. Peak horsepower arrives at 6,400 RPM, and peak torque at 4,400 RPM, per powertrain details published by MoparInsiders. Engine stop-start trims idle fuel use without sacrificing low-end grunt. The eight-speed automatic adds adaptive shift logic tuned for both heavy hauling and rock crawling.
Every 2026 Gladiator uses heavy-duty Dana® 44 solid front and rear axles. A two-speed transfer case is standard as well. Jeep calls these axles segment-exclusive on its Gladiator capability page. That hardware is the foundation for everything the truck does. It handles a merge onto the 60 and a line through a rock garden equally well.

What Is the EPA-estimated Fuel Economy and Estimated Driving Range of the 2026 Jeep Gladiator?
The 2026 Jeep Gladiator carries an EPA-estimated fuel economy rating of 17 mpg city, 22 mpg highway, and 19 mpg combined. The lineup uses one engine and one transmission, so that rating applies to every trim. Ratings are published by the EPA and the U.S. Department of Energy at fueleconomy.gov.
EPA-estimated Fuel Economy and Estimated Range
| Measure | 2026 Jeep Gladiator |
|---|---|
| EPA-estimated City | 17 mpg |
| EPA-estimated Highway | 22 mpg |
| EPA-estimated Combined | 19 mpg |
| Fuel Tank Capacity | 22 gallons |
| Estimated Combined Driving Range | Approximately 418 miles per tank |
| Applies To | Every 2026 Gladiator trim — one engine, one transmission |
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
Paired with a standard 22-gallon fuel tank, the EPA-estimated combined rating works out to roughly 418 miles of driving range per tank.
What Changes Your Real-World Fuel Economy
Published EPA-estimated ratings are a comparison tool, not a promise. Four variables move the number most:
| Variable | Effect on Real-World Efficiency |
|---|---|
| Tire choice | Sport and Sahara on highway or all-season tires track closest to the published EPA-estimated figures. Rubicon and Mojave ride on standard 33-inch all-terrain tires, which add rolling resistance and reduce real-world fuel efficiency. For 2026, Sport S can also be optioned with aggressive all-terrain tires, which has the same effect. |
| Roof and doors removed | Open-air driving increases aerodynamic drag. At highway speeds, fuel consumption rises noticeably. |
| Towing and payload | Heavy trailers and full payloads lower estimated range per tank. Smooth acceleration and steady cruising speeds recover the most distance. |
| Driving style | Hard acceleration and high sustained speeds cost more fuel than any equipment choice on this list. |
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
How Does the Eight-Speed Automatic Support Towing and Trail Work?
The eight-speed automatic provides precise gear spacing and adaptive shift logic. Both work to keep the 3.6L Pentastar V6 inside its optimal powerband during heavy towing and technical off-roading. Standard four-wheel drive comes on every trim level. Together, they keep power flowing to all four wheels when traction drops.
Eight forward ratios matter more than the number suggests. Closely spaced gears let the transmission hold the engine near its torque peak on a grade with a trailer. Without them, the truck hunts between two poorly matched ratios. The same gear spacing smooths torque multiplication at crawling speeds. That limits wheel spin on loose surfaces and holds down transmission fluid temperatures under sustained trail loads.
Paired with the right transfer case, the automatic produces a maximum crawl ratio of up to 77:1 — the figure Jeep publishes for the Gladiator lineup.
What 4×4 Systems Are Available on the 2026 Jeep Gladiator?
Four-wheel drive is standard on every 2026 Gladiator, but the hardware underneath varies. Jeep lists four distinct 4×4 systems across the lineup. The differences show up in low-range gearing. They also show up in whether the system can stay engaged on dry pavement. Note that Jeep expanded the Gladiator range after its initial 2026 announcement, adding the road-oriented Sahara trim, which pairs with a full-time 4×4 system.
2026 Gladiator 4×4 System Comparison
| 4×4 System | Engagement Type | Low-Range Gearing | Availability |
|---|---|---|---|
| Command-Trac® NV241 | Part-time, shift-on-the-fly | Two-speed transfer case, 2.72:1 low-range ratio | Standard: Sport, Sport S, Willys, Mojave |
| Selec-Trac® | Full-time | 2.72:1 low-range ratio | Available on Mojave; full-time 4×4 also offered on Sahara |
| Rock-Trac® NV241 OR | Part-time, shift-on-the-fly | 4:1 low-range ratio | Standard: Rubicon |
| Rock-Trac NV241 OR (full-time variant) | Full-time, shift-on-the-fly | 4:1 low-range ratio | Available as part of a package on Rubicon |
Beyond the transfer cases, several trims add traction hardware. Rubicon carries Tru-Lok® electronic locking differentials at both axles, as shown on Jeep’s Gladiator capability page. An electronic locking rear differential is standard on Willys and Mojave, per trim details published by MoparInsiders. Rubicon is the only trim with the front sway-bar disconnect. One button release lets the front axle articulate freely. Rubicon and Mojave both ride on standard 33-inch all-terrain tires.
2026 Gladiator Off-Road Geometry
Jeep publishes the following figures for the 2026 Gladiator in its model-year announcement.
| Measure | 2026 Jeep Gladiator |
|---|---|
| Approach Angle | 44.7 degrees |
| Departure Angle | 26 degrees |
| Breakover Angle | 20.9 degrees |
| Ground Clearance | Up to 11.6 inches — Mojave delivers the highest of any Gladiator |
| Water Fording | Up to 31.5 inches |
| Maximum Crawl Ratio | Up to 77:1 |
Some drivers head north toward the San Gabriel Mountains. Others head east into the desert. For both, a 4:1 low range is the gap between managing a trail and controlling it.
How Much Can the 2026 Jeep Gladiator Tow?
Properly equipped, the 2026 Jeep Gladiator tows up to 7,700 pounds. Jeep ties that figure to Sport S models on its Gladiator utility page. Jeep also calls it unsurpassed in class among gas midsize trucks. Maximum payload is up to 1,720 pounds. That 7,700-pound rating is not available across the lineup, though. It applies to Sport and Sport S models equipped with the Max Tow Package. Rubicon tops out at 7,000 pounds, while Willys and Mojave are rated at 6,000 pounds, per figures published by MoparInsiders.
On Sport and Sport S, the Max Tow Package with 4.10 Axle Ratio is the option that unlocks the full rating. The package adds a 4.10:1 axle ratio on wide-track Dana M210 front and M220 rear axles. It also adds heavy-duty engine cooling and a Class IV hitch receiver. Willys, Mojave, and Rubicon already carry the Class IV receiver and heavy-duty engine cooling as standard equipment, but their maximum ratings still sit below the Sport S figure.
Standard Towing Hardware
Trailer Sway Control
Senses trailer sway and brakes each wheel individually until the trailer lines back up. Standard on every trim.
Forged Tow Hooks
Heavy-duty forged tow hooks, two at the front and one at the rear, standard across the lineup.
Steel Bed and Tie-Downs
A 5-foot steel bed with integrated tie-downs and an easy-lift tailgate.
Trailer Wiring
Four-pin trailer wiring, with seven-pin wiring available through the tow packages.
Some drivers haul livestock trailers around the horse ranches in Norco. Others pull recreational equipment up highway grades. In both cases, matching the axle ratio and tow package to the load is what makes the difference.
