Powertrain & Engine Architecture
The heart of this Gladiator variant is the 3.0-liter Multijet V6 diesel engine, designated with the EXJ engine code. This engine utilizes a common-rail direct injection system, delivering fuel directly into the cylinders at extremely high pressure for optimized combustion. The engine features a variable geometry turbocharger (VGT) and an intercooler, enhancing both power and efficiency. The V6 configuration provides inherent smoothness and balance, while the DOHC (Double Overhead Camshaft) valvetrain ensures precise valve control. The engine produces 264 horsepower at 3600 rpm and a substantial 600 Nm (442.54 lb.-ft.) of torque between 1400 and 2800 rpm. This broad torque curve is particularly beneficial for towing and off-road driving. Paired with the engine is an eight-speed automatic transmission, providing smooth and efficient gear changes. This transmission is designed to handle the engine’s high torque output and offers a wide range of gear ratios for optimal performance in various driving conditions.
Driving Characteristics
The 3.0 Multijet V6 Automatic Gladiator delivers a distinctly different driving experience compared to its gasoline-powered counterparts. The abundant low-end torque makes it exceptionally capable for towing, hauling, and navigating challenging terrain. While not as quick off the line as the gasoline engines, the diesel offers strong and consistent acceleration throughout the rev range. The eight-speed automatic transmission contributes to a relaxed driving experience, with well-spaced gear ratios that keep the engine in its optimal power band. Compared to manual transmission versions, the automatic prioritizes ease of use and convenience, making it ideal for daily commuting and long-distance travel. The diesel engine’s weight does impact handling slightly, making it feel a bit more planted and less agile than the lighter gasoline models.
Equipment & Trim Levels
The 3.0 Multijet V6 Automatic trim typically included a generous array of standard features. These commonly included air conditioning, power windows and locks, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a rearview camera. Higher trim levels offered upgrades such as leather upholstery, heated front seats, a premium sound system, and advanced safety features like blind-spot monitoring and rear cross-traffic alert. Optional extras often included a winch, rock rails, and upgraded suspension components for enhanced off-road capability. Interior appointments were generally rugged and functional, reflecting the Gladiator’s utilitarian nature.
Chassis & Braking
The Gladiator’s chassis is based on a high-strength steel frame, providing a solid foundation for both on-road and off-road performance. The suspension system consists of a five-link coil spring setup at the front and a multi-link coil spring setup at the rear. The braking system features ventilated discs on all four wheels, providing ample stopping power. Anti-lock brakes (ABS) are standard, enhancing safety and control. The Gladiator’s robust chassis and suspension are designed to withstand the stresses of off-road driving and heavy loads. Stabilizer bars are included to reduce body roll during cornering.
Market Reception & Comparison
The 3.0 Multijet V6 Automatic Gladiator received generally positive reviews, with critics praising its strong torque, fuel efficiency, and off-road capability. However, some reviewers noted that the diesel engine was somewhat noisy compared to gasoline alternatives. Compared to the 3.6-liter V6 gasoline engine, the diesel offered significantly better fuel economy and more torque, making it a popular choice for buyers who prioritized these attributes. The diesel variant typically commanded a higher price than the gasoline models. Reliability reports have been generally favorable, with the 3.0 Multijet engine proving to be a durable and dependable powerplant.
Legacy
The Jeep Gladiator 3.0 Multijet V6 4WD Automatic has established itself as a desirable and capable pickup truck in the used car market. Its robust powertrain, combined with Jeep’s legendary off-road heritage, ensures continued demand. The diesel engine’s longevity and relatively low maintenance costs contribute to its appeal. As a unique offering in the mid-size pickup segment, the Gladiator diesel continues to attract buyers seeking a versatile and capable vehicle that can handle both work and play.
