Engine Specifications
Every 2026 Gladiator ships with a single powertrain: the 3.6L Pentastar V6 paired to an 8-speed automatic transmission, standard 4WD across the lineup. There is no manual, diesel, or V8 option for 2026.

| Fuel type | Regular unleaded, 22.0-gal tank |
Exterior Dimensions
Every 2026 Gladiator shares the same overall footprint; ground clearance and trail geometry shift by trim as the suspension and tires change. Base Sport figures below are Tier-1 verified; the Mojave's desert-tuned suspension delivers the tallest clearance in the lineup.

| Height | 75.0 in |

| Approach / departure angle | 40.8° / 25.0° on Sport; off-road trims (Mojave, Rubicon) run more aggressive geometry with their upgraded suspension and tires |
| Curb weight | 4,695 lb |
Interior Dimensions
The Gladiator is Crew Cab only for 2026, seating five with a 60/40 split-folding rear bench.

| Rear | 42.8 in / 38.3 in / 55.7 in / 55.9 in |
| Total seating | 5 (front bucket seats + 60/40 rear bench) |
Capacity and Capability
Gladiator's headline numbers require the right configuration: the 7,700-lb max tow figure is specific to Sport S and up with the Max Tow Package and 4.10 axle ratio, not the base Sport as it sits on the lot.
| Spec | Value |
|---|---|
| Standard towing (no package) | Up to 4,500 lb |
| Max towing, properly equipped | Up to 7,700 lb (Sport S+, Max Tow Package w/4.10 axle) |
| Standard payload | 1,025 lb |
| Max 4x4 payload | Up to 1,720 lb |
| Bed length | 60.3 in (tailgate closed) |
| Bed width | 56.8 in |
| Bed construction | Steel box, integrated tie-downs, easy-lift tailgate |
The available Cargo Group with Trail Rail System adds a 115-volt bed outlet, a secure accessory-mounting system, and a roll-up tonneau cover, details covered on our towing capacity page.
Wheels, Tires, and Brakes
| Spec | Value |
|---|---|
| Standard wheels | 17 x 7.5 in painted alloy |
| Standard tires | 245/75R17 all-season |
| Spare | Full-size, underbody-mounted behind the rear axle |
| Brakes | 4-wheel ABS, front and rear ventilated disc, standard emergency braking assist |
| Axles | Dana 44 solid front and rear (segment-exclusive heavy-duty) |
Off-road trims step up to wider all-terrain or mud-terrain rubber and, on Rubicon and Mojave, locking differentials, covered trim-by-trim on our trim comparison.
Fuel Economy and Range
| City | Highway | Combined |
|---|---|---|
| 17 mpg | 22 mpg | 19 mpg |
With the single 3.6L V6 powering every trim, fuel economy runs consistent across the lineup, a 22.0-gallon tank gives a combined range in the mid-370s to high-400s of miles depending on how you drive.
Safety and Compliance
Every 2026 Gladiator carries a substantial standard safety list, well ahead of what "base truck" usually implies:
Available packages (Safety Group, Technology Group) layer on additional driver-assistance features by trim, see the trim comparison for what's standard versus optional at each level.
