The Jeep Gladiator Rubicon 2023 is a remarkable vehicle that combines rugged off-road capabilities with modern features. This review explores its performance, design, and the various features that make it a standout choice for adventure enthusiasts. The Gladiator Rubicon sits at the top of the Gladiator lineup, offering the most off-road hardware while still providing the utility of a mid-size pickup bed. For drivers who want a truck that can crawl rocks, ford streams, and then commute to work the next day, the 2023 Gladiator Rubicon delivers a unique blend of capability and everyday usability.

Performance Overview

The performance of the 2023 Gladiator Rubicon is one of its most impressive aspects. Equipped with a powerful engine and advanced off-road technology, it is designed to tackle the toughest terrains. The heart of the Rubicon is the 3.6-liter Pentastar V6 engine, which produces 285 horsepower and 260 lb-ft of torque. This engine has proven reliable across the Jeep lineup and provides adequate power for daily driving and off-road excursions.

Engine Options

The standard and base engine for the Gladiator Rubicon is the 3.6-liter V6. It features an aluminum block and heads, variable valve timing, and delivers smooth, linear power. For those needing superior low-end torque, particularly for towing or rock crawling, Jeep offers the optional 3.0-liter EcoDiesel V6. The diesel engine produces 260 horsepower but a substantial 442 lb-ft of torque, available from just 1,400 rpm. This makes the diesel Gladiator Rubicon a strong choice for towing heavy trailers or navigating steep trails without downshifting.

Transmission Choices

The Gladiator Rubicon comes standard with a six-speed manual transmission, one of the last trucks in its class to offer a manual gearbox. The manual features a dual-mass flywheel for smoother engagement and is paired with a heavy-duty clutch. For drivers who prefer automatic shifting, an eight-speed automatic transmission is optional. The automatic provides quick, smooth shifts and includes a manual shift gate for driver control. Both transmissions are mated to the Rock-Trac 4x4 system.

4x4 System: Rock-Trac

The 4x4 system in the Gladiator Rubicon is the Rock-Trac system, a part-time two-speed transfer case with a 4:1 low-range gear ratio. This deep low-range gearing allows the Gladiator to crawl over obstacles at walking speed with precise throttle control. The system includes a shift-on-the-fly capability from 2WD to 4WD High. The four-wheel-drive system is complemented by heavy-duty Dana 44 front and rear axles, which can handle the increased torque from both engines and the stresses of hard off-road use.

Towing and Payload Capacity

The 2023 Gladiator Rubicon, when equipped with the optional Max Tow Package, can tow up to 7,700 pounds. The Rubicon standard configuration has a slightly lower towing capacity of 6,000 pounds due to the more aggressive off-road suspension and tires. Payload capacity ranges from 1,100 to 1,200 pounds depending on options. These figures place the Gladiator Rubicon in a middle ground among mid-size trucks, adequate for a small camper or a couple of dirt bikes, but not as high as some competitors like the Ford Ranger or Chevrolet Colorado.

Fuel Economy

Fuel economy for the gasoline Gladiator Rubicon is not its strong suit. EPA estimates are 16 mpg city and 23 mpg highway with the manual transmission, and 16/22 with the automatic. The diesel engine improves efficiency significantly, offering an estimated 22 mpg city and 28 mpg highway, along with a larger driving range. Real-world mixed driving typically returns around 18-20 mpg for the V6 and 24-26 for the diesel.

Off-Road Features and Capability

The Gladiator Rubicon is built specifically for off-road adventures. Jeep packs this trim with the most comprehensive off-road hardware available in a mid-size truck. From the factory, it is equipped to handle trails that many modified trucks struggle with.

Locking Differentials

The front and rear axle locking differentials provide improved traction on slippery surfaces. When engaged, they lock both wheels on each axle together, ensuring maximum traction regardless of wheel slip. The differentials can be engaged at low speeds and are controlled by an interior switch. They are essential for rock crawling and deep mud.

Electronic Stabilizer Bar Disconnect

The Rubicon includes a front electronic sway bar disconnect system. Pressing a button in the cabin disconnects the front anti-roll bar, allowing maximum suspension articulation. This feature allows the front wheels to drop further into holes or climb over rocks without lifting the opposite wheel, maintaining contact with the ground. It is a key feature that sets the Rubicon apart from other Gladiator trims and most competitors.

Suspension System

The suspension system in the Gladiator Rubicon is designed for off-road flex and durability. It uses heavy-duty shocks with remote reservoirs (Fox shocks on some model years, or standard twin-tube shocks) and springs tuned for off-road articulation. The suspension provides a 1-inch factory lift over the Sport and Overland trims. The long-travel suspension soaks up bumps and ruts on the trail while still maintaining reasonable on-road control.

Skid Plates and Underbody Protection

Underbody skid plates protect vital components from damage during off-road excursions. The Gladiator Rubicon comes standard with skid plates for the fuel tank, transfer case, and automatic transmission. These are made of steel and provide peace of mind when traversing rocky terrain.

Approach, Departure, and Breakover Angles

With an impressive approach angle of 43.6 degrees and a departure angle of 26 degrees, the Gladiator can easily navigate steep inclines and declines. The breakover angle is 20.3 degrees. These numbers are excellent for a mid-size pickup truck, though the longer wheelbase compared to the Wrangler limits breakover angle. The Rubicon rides on 33-inch all-terrain tires (LT285/70R17) that provide good traction in mud, sand, and rock.

Water Fording

The Gladiator Rubicon can ford water up to 30 inches deep. Jeep seals the engine intake and various electrical components to allow safe crossing of streams and shallow rivers. This depth is sufficient for most off-road trails and even moderate creek crossings.

Exterior Design and Styling

The 2023 Gladiator Rubicon retains the iconic Jeep design language, with a seven-slot grille, round headlights, and a cut-down windshield that creates a classic Jeep profile. The Rubicon trim adds visual cues that set it apart, including unique hood decals, red tow hooks, and black fender flares.

Removable Roof and Doors

Like the Wrangler, the Gladiator Rubicon offers removable roof panels and doors. The Freedom Top consists of three removable panels: two small front panels and a large rear panel. The doors can be removed with simple tools (or optional half doors). Jeep even includes a tool kit for removing the panels. This open-air experience is unique in the truck segment and appeals to outdoor enthusiasts who want to enjoy the elements.

Bed Features and Utility

The Gladiator's five-foot bed is not the largest in its class, but it offers useful features. The bed includes a spray-in bedliner, tie-down cleats (four fixed and two movable rails), and an available 115-volt power outlet. The tailgate is damped and can be lowered easily. The bed can accommodate items such as dirt bikes, camping gear, or lumber for small projects. The Gladiator Rubicon also benefits from the Wrangler's proven fold-flat front passenger seat, allowing long items to be carried inside the cabin if the roof panels are removed.

Available Colors

Jeep offers a wide array of exterior colors for 2023, including standard shades like Bright White, Black, and Silver Zynith. Special edition colors such as High Velocity (yellow), Earl (gray-blue), and Go Mango (orange) are available at extra cost. The Rubicon also offers optional black steel wheels or polished aluminum wheels, both 17 inches in diameter.

Interior and Comfort

Inside the Gladiator Rubicon, drivers and passengers can enjoy a blend of ruggedness and comfort. The interior is designed to withstand the elements while providing a pleasant driving experience. Jeep uses durable, easy-to-clean materials that hold up well to dirt and dust.

Seating and Upholstery

The Rubicon features standard black cloth seats with red accent stitching and Rubicon embroidery. The cloth seats are water-repellent and treated to resist stains. For buyers who prefer leather, an optional leather-trimmed interior is available, which includes heated front seats and a heated steering wheel. The front seats are supportive and comfortable for long trips, with manual adjustments as standard and power adjustments optional.

Infotainment System

The Uconnect infotainment system comes with a 7-inch or optional 8.4-inch touchscreen display. The system includes Apple CarPlay and Android Auto compatibility, Bluetooth hands-free calling, and satellite radio. The 8.4-inch system adds navigation, HD radio, and a premium Alpine or optional more powerful audio system. Uconnect is one of the most user-friendly systems on the market, with quick response times, intuitive menus, and physical knobs for volume and tuning.

Climate Control

Dual-zone automatic climate control is standard on Rubicon. The controls are large and easy to operate with gloves on. The air conditioning system is powerful enough to cool the cabin even with the roof panels removed.

Storage Options

Ample storage space is available throughout the cabin. Under the rear seat, there is a lockable storage bin that can hold valuables. The front center console is large, and the glove box is lockable. Door pockets have molded bottle holders. The rear seatbacks can be folded forward to create additional cargo space, though the seat bottom does not flip up easily as in some competitors.

Rear Seat Comfort

The rear seat offers good headroom and legroom for a mid-size truck. Two adults can sit comfortably on short trips, but three across may be tight due to the width and transmission tunnel. The rear seatback angle is slightly upright but acceptable. Rear passengers get air vents and a USB port.

Safety Features

Safety is a priority in the Gladiator Rubicon 2023, with a suite of advanced safety features designed to protect occupants on and off the road. While the Gladiator's body-on-frame construction offers durability, it does not have the highest crash test scores due to its solid axles and removable roof. However, the Rubicon includes a full complement of electronic safety aids.

Standard Safety Equipment

The 2023 Gladiator Rubicon comes standard with a rearview camera, electronic stability control, traction control, and four-wheel antilock disc brakes. It also includes side-curtain airbags and front-seat side airbags. The lower anchors for child seats are provided in the rear seat.

Available Driver Assistance

Jeep offers a suite of advanced driver assistance features on the Gladiator Rubicon, available as part of the Advanced Safety Group package. This package includes adaptive cruise control, which maintains a set distance from the vehicle ahead. Blind-spot monitoring with rear cross-path detection alerts drivers to vehicles in their blind spots, enhancing lane change safety. Forward collision warning with active braking detects potential collisions and alerts the driver to take action. ParkSense rear park-assist sensors and an integrated trailer brake controller are also available.

Crash Test Ratings

The National Highway Traffic Safety Administration (NHTSA) awarded the 2023 Gladiator four out of five stars overall. The Insurance Institute for Highway Safety (IIHS) has not given the Gladiator top ratings in all categories, primarily due to its limited roof strength (typical of removable roofs) and headlight performance. However, the Gladiator's real-world safety record is solid, with many owners citing its high stance and visibility as safety benefits.

Technology and Connectivity

Beyond infotainment, the Gladiator Rubicon offers several technologies that enhance the off-road experience. The Jeep Off-Road Pages app provides real-time data on various vehicle parameters, including power distribution, drivetrain status, and vehicle angles. The system also includes a performance gauge that displays throttle position, steering angle, and suspension articulation.

TrailCamera

The available TrailCam system places a forward-facing camera in the front grille. This camera provides a clear view of the terrain directly ahead, helping drivers position tires over obstacles. The image is displayed on the touchscreen and can be overlaid with guidelines. This feature is invaluable for rock crawling and tight trails.

Cooling and Engine Protection

The Gladiator Rubicon includes a heavy-duty engine cooling system with a larger radiator and electric fan. An auxiliary transmission cooler is standard with the automatic transmission. These systems help prevent overheating during slow-speed, high-load off-road driving.

Comparisons with Competitors

The 2023 Jeep Gladiator Rubicon competes primarily with other off-road-oriented mid-size trucks: the Ford Ranger (especially the Tremor and Raptor predecessors), the Toyota Tacoma TRD Pro, and the Chevrolet Colorado ZR2. Each offers similar capability but with different strengths.

Jeep Gladiator Rubicon vs. Ford Ranger

The Ford Ranger is longer and offers more towing capacity (up to 7,500 pounds). However, the Ranger's off-road trim (Tremor) does not have locking front and rear differentials, nor a sway bar disconnect. The Ranger's independent front suspension provides better on-road ride quality, but the Gladiator's solid front axle offers more articulation for rock crawling.

Jeep Gladiator Rubicon vs. Toyota Tacoma TRD Pro

The Tacoma TRD Pro has a legendary reputation for reliability and a more refined interior in some ways. The Tacoma's 4WD system includes a locking rear differential but not a front locker. The Gladiator Rubicon outshines the Tacoma in crawling capability due to the sway bar disconnect and front locker. The Tacoma's V6 is less powerful than the Gladiator's, and the Tacoma lacks a diesel option.

Jeep Gladiator Rubicon vs. Chevrolet Colorado ZR2

The Colorado ZR2 features spool-valve dampers (Multimatic DSSV) that provide exceptional on-road handling and impressive off-road damping. The ZR2 has front and rear locking differentials, but its front suspension is independent, which limits articulation compared to the Gladiator's solid axles. The Colorado ZR2's diesel engine is also a major draw, with comparable torque to the Gladiator diesel. However, the Gladiator offers the unique open-air experience and a more classic off-road feel.

Verdict: Who Should Buy the 2023 Jeep Gladiator Rubicon?

The Jeep Gladiator Rubicon 2023 is a powerful and versatile vehicle that excels in off-road performance while offering a comfortable and feature-rich interior. With its impressive capabilities and safety features, it stands out as an excellent choice for those seeking adventure and reliability. The Rubicon trim is the ultimate off-road version of the Gladiator, and it is best suited for enthusiasts who plan to tackle serious trails regularly. While its on-road ride is not as refined as some competitors, and fuel economy is lackluster, the Gladiator Rubicon offers a level of off-road capability that no other production truck can match straight from the factory.
