Big changes are on the horizon for the Jeep® brand’s hybrid lineup, and the 2026 Jeep Gladiator Hybrid is set to be a major beneficiary. Sources indicate that the upcoming Gladiator 4xe model will feature the advanced ZF 8HP80PH plug-in hybrid (PHEV) 8-speed automatic transmission. This upgrade promises significant enhancements in power, efficiency, and electric driving range compared to the current transmission used in the Wrangler 4xe. This means the 2026 Jeep Gladiator hybrid is poised to offer a superior driving experience both on and off the road.
Power and Performance Revolution

The heart of the 2026 Jeep Gladiator hybrid’s improvement lies in the 8HP80PH transmission. Its electric motor alone is capable of delivering a peak output of 215 horsepower (160 kW) and 332 lb-ft (450 N•m) of torque. This is a substantial leap from the current 8HP75PH unit’s 134 horsepower (100 kW) and 181 lb-ft (245 N•m) found in models like the 2024 Wrangler Sahara Unlimited 4xe. For the Jeep Gladiator hybrid, this translates to faster acceleration, smoother gear transitions, and improved off-road prowess, all while contributing to better fuel economy.
One of the key innovations of the ZF 8HP80PH is its integrated and modular design. Unlike older hybrid systems with separate electronic control units, this transmission cleverly incorporates the motor’s electronic control directly into the transmission housing. This design simplifies wiring, increases safety, streamlines assembly, and ultimately reduces maintenance costs for the Jeep Gladiator hybrid owner.
Next-Gen Electric Motor Technology

Further enhancing the 2026 Jeep Gladiator hybrid is ZF’s next-generation high-voltage electric motor within the transmission. This advanced motor utilizes welded copper rods instead of traditional coiled copper wire. This innovative approach increases the copper filling rate, resulting in greater power density without increasing the physical size of the transmission unit itself. This compact yet powerful motor is crucial for maximizing the efficiency and performance of the Jeep Gladiator hybrid.
Efficiency Boost with Hydraulic Control
The 2026 Jeep Gladiator hybrid also benefits from an enhanced hydraulic control system. By employing direct shift valves in a new, smaller hydraulic unit, the system reduces the required hydraulic fluid from 3.1 liters to a mere 1.8 liters. This reduction minimizes drag loss and optimizes the overall performance and efficiency of the hybrid system in the Gladiator.
Innovative Power Shunt Pump System
Adding to the technological advancements, the 8HP80PH transmission introduces a single power shunt pump system, replacing the conventional dual-pump setup. In scenarios where the internal combustion engine is off, a small electric motor takes over, driving the oil pump to maintain hydraulic pressure. This ensures seamless operation across various driving conditions for the Jeep Gladiator hybrid, whether in electric mode or hybrid mode.
Extended Electric-Only Driving

The ZF 8HP80PH transmission significantly boosts the electric-only capabilities of the 2026 Jeep Gladiator hybrid. It is anticipated that models equipped with this transmission will achieve up to 50 km (31 miles) of electric-only range and reach speeds of up to 120 km/h (74.5 mph) without engaging the gasoline engine. While off-road driving may slightly alter these figures for the Gladiator, the potential for extended emissions-free driving is a major advantage. This allows for quiet, zero-emission commuting while retaining the Jeep Gladiator’s legendary off-road capability.
The integration of the ZF 8HP80PH transmission marks a significant step forward for Jeep’s hybrid technology, particularly for the 2026 Jeep Gladiator hybrid. Production for the Gladiator 4xe is expected to commence in Q1 2026 at the Toledo Assembly Complex in Toledo, Ohio. The 2026 Jeep Gladiator hybrid is shaping up to be a powerful, efficient, and technologically advanced pickup truck, ready for both adventure and daily driving.
