2026 Jeep Wrangler Engine Options & Specs | Fontana CDJR
The 2026 Jeep Wrangler offers three gas powertrains: a standard 3.6-liter Pentastar® V6, an available 2.0-liter turbocharged four-cylinder, and a 6.4-liter SRT® HEMI® V8 offered on limited-edition 392 models. Two powertrains that appeared in earlier Wranglers are gone. The 3.0-liter EcoDiesel V6 was retired earlier in this generation. Jeep ended the 4xe plug-in hybrid after the 2025 model year, as Stellantis phased out its North American plug-in programs. For 2026, gas is the whole story.
The base engine across the lineup is the naturally aspirated 3.6-liter Pentastar V6, standard on the Sport, Sport S, Willys, Rubicon, and Rubicon X. This engine is widely recognized for its linear power delivery and long-term durability. It is also the only engine in the 2026 lineup that lets you choose between a six-speed manual and an eight-speed automatic. That keeps it a favorite among off-road enthusiasts who prefer picking their own gears on the trail.
For drivers who want stronger low-end pull in daily driving, the 2.0-liter turbocharged four-cylinder is the energetic alternative. It delivers high torque early in the rev range. That helps with quick acceleration and throttle response when passing or climbing grades. It comes standard on the Sahara and pairs exclusively with the eight-speed automatic.
At the top of the range sits the 6.4-liter HEMI V8. For 2026 it appears on two limited-edition, limited-allocation models in Jeep’s Twelve 4 Twelve series. The four-door Moab 392 launched in November 2025. It succeeds the Rubicon 392, which Jeep retired after the 2025 model year. The Willys 392 followed in February 2026. Because each Twelve 4 Twelve release is built in limited quantities, V8 availability depends on remaining allocation.
Drivers exploring trail access near the Cajon Pass often compare how each engine handles sustained elevation climbs and rock crawling. If you want to experience these powertrains in person, our Highland Avenue showroom here in Fontana is a short drive from Rancho Cucamonga and San Bernardino.
What Are the Horsepower and Torque Ratings for Each 2026 Wrangler Powertrain?
Output for the 2026 Jeep Wrangler spans from 270 horsepower in the turbo-four to 470 horsepower in the V8. Each engine is tuned for a different priority, whether that is smooth highway cruising or low-speed obstacle clearance.
2026 Wrangler Engine Specifications
| Engine | Horsepower | Torque | Transmission | Standard On |
|---|---|---|---|---|
| 3.6L Pentastar V6 | 285 hp | 260 lb-ft | 6-speed manual or 8-speed automatic | Sport, Sport S, Willys, Rubicon, Rubicon X |
| 2.0L Turbo I-4 | 270 hp | 295 lb-ft | 8-speed automatic | Sahara |
| 6.4L HEMI V8 | 470 hp | 470 lb-ft | 8-speed automatic | Moab 392 and Willys 392 (limited edition) |
2026 model-year specifications, feature content, and limited-edition model availability are preliminary and subject to change at any time. Confirm current details with the dealership before purchase.
Horsepower and torque ratings above are published by Stellantis in its 2026 Jeep Wrangler model-year release.
Matching these numbers to your driving habits comes down to how you plan to use the vehicle. The turbo-four carries 35 lb-ft more torque than the V6, and it delivers that torque lower in the rev range. That makes it nimble in urban traffic and quick to respond when merging onto the highway. The Pentastar V6 offers a proven, predictable throttle profile instead. Seasoned off-roaders trust it when technical terrain calls for precise pedal modulation.

Does the 2026 Jeep Wrangler Offer a Manual Transmission?
Yes. The 2026 Jeep Wrangler offers a six-speed manual transmission, but only with the standard 3.6-liter Pentastar V6. Both the turbo-four and the 6.4-liter V8 come exclusively with the eight-speed automatic.
The six-speed manual’s mechanical clutch engagement provides the direct feel that traditional 4×4 drivers value. Jeep does not offer the manual gearbox on the turbocharged or V8 engines.
The eight-speed automatic is tuned for smooth gear transitions during daily commutes while optimizing shift points for off-road use. It includes adaptive gear shifting and manual control modes. That lets drivers hold a specific gear when descending steep trails or hauling gear.
What Is the EPA-Estimated Fuel Economy and MPG Rating for the 2026 Wrangler?
EPA-estimated fuel economy for the 2026 Jeep Wrangler ranges from 14 mpg combined on the V8 up to 21 mpg combined on the turbocharged four-cylinder. Ratings vary by engine, transmission, and body style.
Four-Door EPA-Estimated Fuel Economy by Engine
| Engine & Transmission (Four-Door) | EPA-Estimated City | EPA-Estimated Highway | EPA-Estimated Combined |
|---|---|---|---|
| 2.0L Turbo I-4, 8-speed automatic | 20 mpg | 22 mpg | 21 mpg |
| 3.6L V6, 8-speed automatic | 18 mpg | 23 mpg | 20 mpg |
| 3.6L V6, 6-speed manual | 16 mpg | 22 mpg | 19 mpg |
| 6.4L HEMI V8, 8-speed automatic | 13 mpg | 16 mpg | 14 mpg |
Two-Door Ratings and Fuel Capacity
Two-door models are rated separately. The two-door turbo-four earns an EPA-estimated 20 mpg city, 23 mpg highway, and 21 mpg combined. Fuel capacity also differs by body style. Four-door Wranglers hold 21.5 gallons, and two-door models hold 17.5 gallons, per Jeep’s published Wrangler FAQ.
Real-world results will differ from the EPA-estimated figures above, influenced by aerodynamic drag, tire size, and driving conditions. Upgrading to larger all-terrain tires or adding heavy armor protection increases weight and rolling resistance. That slightly reduces estimated highway fuel economy. The foothill inclines around Claremont are a good example of how consumption shifts when you move from flat valley roads to mountain grades.
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.
Which 2026 Jeep Wrangler Engine Is Recommended for Off-Roading?
For technical trail work, the 3.6-liter Pentastar V6 remains the top pick. Its predictable power curve and available manual control give drivers the precise pedal modulation that low-speed obstacles demand. Selecting the right engine comes down to the terrain you frequent most.
Which Engine Suits Which Terrain
Technical Trails & Rock Crawling
The V6 offers a proven, predictable throttle profile. Precise pedal modulation over technical terrain is easier to meter with the naturally aspirated engine, and the available six-speed manual puts gear selection directly in the driver’s hands.
Overlanding & Remote Travel
The V6 offers traditional mechanical simplicity. Running on regular 87-octane gasoline, it provides peace of mind when traveling deep into remote regions where premium fuel may be unavailable.
High-Speed Sand & Mud
The 6.4-liter HEMI V8 and the 2.0-liter turbo deliver rapid throttle response that helps maintain momentum through deep mud pits, loose sand dunes, and steep washouts.
Every 2026 Wrangler is Trail Rated® and comes with four-wheel drive standard. The figures below are Jeep’s published maximums for a properly equipped vehicle. The exact rating for any individual Wrangler depends on its configuration.
2026 Wrangler Off-Road and Towing Specifications
| Capability Specification | 2026 Jeep Wrangler (Properly Equipped) |
|---|---|
| Maximum ground clearance | 12.9 inches |
| Maximum water fording | Up to 35 inches |
| Maximum crawl ratio | Up to 100:1 |
| Approach angle | 47.4 degrees |
| Departure angle | 40.4 degrees |
| Breakover angle | 26.7 degrees |
| Maximum towing, four-door | 5,000 pounds |
| Maximum towing, two-door | 2,000 pounds |
Geometry figures vary by body style and equipment. The 47.4-degree approach angle is an available four-door figure, breakover angle reaches up to 32.4 degrees on two-door models, and maximum ground clearance requires the available Xtreme 35-inch Tire Package.
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
Common Questions About 2026 Jeep Wrangler Performance and Estimated Efficiency
Does the 2026 Jeep Wrangler require premium gasoline?
It depends on the engine. Both the 3.6-liter Pentastar V6 and the 2.0-liter turbocharged four-cylinder are engineered to run on regular unleaded gasoline with an octane rating of 87. For the 2.0-liter turbo, Jeep notes that using 91-octane or higher premium gasoline allows the engine to achieve optimal performance. The 6.4-liter SRT HEMI V8 is the exception: Jeep specifies 91-octane or higher premium gasoline for the 392 models, so plan on premium fuel if you choose the Moab 392 or Willys 392.
What is the maximum weight a 2026 Jeep Wrangler can safely pull?
When properly equipped, four-door 2026 Jeep Wrangler models can tow up to a maximum of 5,000 pounds. A standard four-door is typically rated at 3,500 pounds, and two-door models are rated at 2,000 pounds due to their shorter wheelbase.
Is the 3.0-liter EcoDiesel engine still available on the 2026 Wrangler?
No. The 3.0-liter EcoDiesel V6 was phased out during earlier model production runs and is not offered on the 2026 Jeep Wrangler. Buyers seeking maximum torque should look at the 6.4-liter HEMI V8 in the limited-edition Moab 392 and Willys 392, which deliver 470 lb-ft.
