Big changes are on the way for Jeep’s hybrid lineup, and the 2026 Jeep Gladiator 4xe is set to be a major beneficiary. Sources indicate that both the 2026 Jeep Wrangler Unlimited 4xe and the new Gladiator 4xe models will feature the cutting-edge ZF 8HP80PH plug-in hybrid (PHEV) 8-speed automatic transmission. This advanced gearbox promises significant improvements in power, efficiency, and electric driving range compared to the current 8HP75PH transmission used in the Wrangler 4xe. For Jeep Gladiator enthusiasts looking for enhanced performance and eco-friendly driving, the 2026 4xe model is shaping up to be a game-changer.
Enhanced Power and Performance Metrics

The new 8HP80PH transmission is engineered for substantial power gains. Its electric motor alone can deliver a peak output of 215 horsepower (160 kW) and a robust 332 lb-ft (450 N•m) of torque. This is a significant leap from the 8HP75PH’s 134 horsepower (100 kW) and 181 lb-ft (245 N•m). The result is expected to be quicker acceleration, smoother gear transitions, and improved off-road capability for the Jeep Gladiator 4xe. These enhancements are crucial for maintaining Jeep’s legendary off-road prowess while embracing electrification. Moreover, this power boost comes hand-in-hand with increased fuel efficiency, making the 2026 Jeep Gladiator 4xe an appealing option for both adventure and daily driving.
A key innovation in the ZF 8HP80PH is its integrated and modular design. Unlike older hybrid systems that used separate electronic control units, this transmission integrates the motor’s electronic control directly into the transmission housing. This smart design reduces wiring complexity, enhances overall safety, simplifies vehicle assembly, and ultimately lowers maintenance costs for Jeep Gladiator 4xe owners.
Next-Gen Electric Motor Technology

The performance improvements in the 2026 Jeep Gladiator 4xe are also attributed to ZF’s next-generation high-voltage electric motor. This motor utilizes welded copper rods instead of traditional coiled copper wire. This advanced design increases the copper fill rate within the motor, leading to greater power density without increasing the physical size of the transmission unit. This efficient use of space and materials is key to delivering more power in a compact package, perfectly suited for the Jeep Gladiator 4xe’s demanding applications.
Advanced Hydraulic Control for Efficiency
Further enhancing the efficiency of the new transmission in the Jeep Gladiator 4xe is an upgraded hydraulic control system. By implementing direct shift valves and a new small-volume hydraulic unit, the system reduces the amount of hydraulic fluid needed from 3.1 liters to just 1.8 liters. This reduction in fluid volume minimizes drag loss within the transmission and optimizes the overall system performance, contributing to better fuel economy and responsiveness in the Jeep Gladiator 4xe.
Innovative Power Shunt Pump System
The 8HP80PH transmission also features an innovative single power shunt pump system, replacing the traditional dual-pump setup. When the internal combustion engine is not running, a small electric motor drives the oil pump. This maintains hydraulic pressure and ensures smooth operation of the Jeep Gladiator 4xe’s transmission across various driving conditions, including electric-only mode and start-stop scenarios. This system improves efficiency and ensures consistent performance regardless of the driving mode.
Extended Electric-Only Driving Range

For Jeep Gladiator 4xe drivers prioritizing emissions-free driving, the ZF 8HP80PH transmission offers impressive electric-only capabilities. Jeep 4xe models equipped with this transmission are projected to achieve up to 50 kilometers (31 miles) of electric range and reach speeds up to 120 km/h (74.5 mph) without engaging the gasoline engine. While the off-road focus of the Wrangler and Gladiator might slightly affect these figures in real-world conditions, the potential for significant electric driving is clearly there. This translates to quieter, emissions-free commutes and the ability to enjoy nature trails silently, all while retaining the Jeep Gladiator’s legendary off-road capabilities.
The introduction of the ZF 8HP80PH transmission in the 2026 Jeep Gladiator 4xe and Wrangler 4xe marks a significant step forward in Jeep’s commitment to hybrid technology. Sources suggest that production for the updated 2026 Jeep Wrangler 4xe is slated to begin in Q4 2025, with the Jeep Gladiator 4xe following in Q1 2026. Both models will be manufactured at the Toledo Assembly Complex in Toledo, Ohio, heralding a new era of electrified capability for the iconic Jeep brand.
