The Jeep® brand is set to revolutionize its hybrid lineup in 2026, introducing significant upgrades to both the Jeep Wrangler Unlimited and the highly anticipated Jeep Gladiator 4xe models. Sources confirm that the 2026 Jeep Gladiator 4xe will feature ZF’s cutting-edge 8HP80PH plug-in hybrid (PHEV) 8-speed automatic transmission. This advanced transmission system promises a substantial leap in power, efficiency, and electric driving range compared to the current 8HP75PH transmission used in the Wrangler 4xe.
Enhanced Power and Performance of the Gladiator 4xe
The 8HP80PH transmission boasts a remarkable peak power output of 215 horsepower (160 kW) and 332 lb-ft (450 N•m) of torque from its electric motor. This is a considerable enhancement over the 134 horsepower (100 kW) and 181 lb-ft (245 N•m) offered by the existing 8HP75PH unit. For the Jeep Gladiator 4xe, this translates to quicker acceleration, smoother gear transitions, and improved off-road prowess, all while contributing to better fuel economy. The integrated design and modularity of the ZF 8HP80PH transmission are key innovations. Unlike older hybrid systems with separate electronic control units, this system fully integrates the motor’s electronic control within the transmission housing. This sophisticated integration streamlines wiring, enhances safety, simplifies assembly, and ultimately reduces maintenance expenses for Jeep Gladiator 4xe owners.
Next-Gen Electric Motor in the 2026 Gladiator 4xe
The advanced performance of the Gladiator 4xe’s new transmission is further amplified by ZF’s next-generation high-voltage electric motor. This motor employs welded copper rods instead of traditional coiled copper wire, a design that increases the copper fill rate. The result is a greater power density achieved without increasing the physical dimensions of the transmission itself. This compact yet powerful motor is crucial for maintaining the Jeep Gladiator 4xe’s rugged capabilities without compromising space or adding unnecessary weight.
Optimized Hydraulic Control System for Efficiency
Further boosting the efficiency of the Jeep Gladiator 4xe is an upgraded hydraulic control system within the 8HP80PH transmission. By utilizing direct shift valves, this new small-volume hydraulic unit reduces the required hydraulic fluid capacity from 3.1 liters down to just 1.8 liters. This reduction minimizes drag loss and optimizes the overall system performance, contributing to the enhanced fuel efficiency and responsiveness of the Gladiator 4xe.
Innovative Power Shunt Pump System
The 8HP80PH transmission introduces a single power shunt pump system, replacing the conventional dual-pump setup. In scenarios where the internal combustion engine is inactive, a small electric motor takes over, driving the oil pump to maintain hydraulic pressure. This innovative system ensures seamless operation across diverse driving conditions for the Jeep Gladiator 4xe, whether on city streets or tackling challenging off-road terrains.
Gladiator 4xe Electric-Only Driving Range and Capabilities
The ZF 8HP80PH transmission empowers the 2026 Jeep Gladiator 4xe with impressive electric-only capabilities. It is anticipated that Gladiator 4xe models equipped with this transmission will offer up to 50 km (31 miles) of all-electric range and reach speeds of up to 120 km/h (74.5 mph) without engaging the gasoline engine. This feature allows for quiet, zero-emission driving for daily commutes while preserving the Jeep Gladiator’s legendary off-road capability. As Jeep advances hybrid technology, the integration of the ZF 8HP80PH transmission marks a significant advancement. According to sources, production of the 2026 Jeep Wrangler 4xe is slated to begin in Q4 2025, with the Jeep Gladiator 4xe following in Q1 2026. Both groundbreaking models will be manufactured at the Toledo Assembly Complex in Toledo, Ohio, heralding a new era for Jeep’s hybrid offerings and the future of the Jeep Gladiator 4xe.
