Powertrain
The 3.6 L Pentastar VVT V6 gasoline engine remains available from the existing Wrangler and Wrangler Unlimited, and is standard on all models, though it has been redesigned for improved fuel economy. The engine features an Aisin AL6 six-speed manual transmission as standard equipment, with an 850RE Torqueflite eight-speed automatic transmission being optional. The automatic transmission made its debut in the 2018 Jeep Grand Cherokee (WK2), replacing the older Torqueflite 845RE unit. The eight-speed automatic unit will feature a traditional shifter. The engine performance is unchanged from the previous model at 285 Hp and 260 lbft. This is only offered on Wrangler models sold in North America, Middle East, Australia, and New Zealand. The new engine features an optional mild hybrid system branded as eTorque for improved fuel economy and off-road performance.[9]
A 2.0 L turbocharged four-cylinder (Inline-4) FCA Global Medium Engine is available on all models. Paired exclusively with the 850RE Torqueflite eight-speed automatic transmission and including the eTorque system, the engine produces 270 Hp and 295 lbft combined. This is the only gasoline engine offered in Europe, China, Singapore, and India. In North America, this engine had late availability, and the Wrangler was launched with the existing 3.6 L Pentastar V6 gasoline engine.[10] Jeep cancelled the 2.0L eTorque hybrid in 2020.[11]
A 3.0 L EcoDiesel V6 turbodiesel engine, built by VM Motori, became available in North America in 2020 (same engine already available in the Jeep Grand Cherokee (WK2) and the Ram 1500.[12]) It produces 260 Hp and 600 Nm.[13]
For the rest of the world (except North America) a 2.2 L 16V Multijet II turbo four-cylinder diesel engine producing 200 Hp and 450 Nm with Start&Stop is available.
A plug-in hybrid model called the 4xe was released in 2021. Power and torque ratings are 375 Hp horsepower and 470 lbft of torque.[14] It uses a 17 kWh lithium-ion battery pack that gives it an EPA-estimated range of 21 mi and an EPA-rated 49 MPGe.[15] It is available in China, Europe, and the United States.[16] For 2022, the 4xe became the only variant of the Wrangler offered in Europe.[17] In 2025, Stellantis discontinued the Jeep Wrangler 4xe from the US market (along with the Dodge Hornet, Chrysler Pacifica Plug-in Hybrid, and Jeep Grand Cherokee 4xe) citing poor sales and loss of federal EV tax credits. Stellantis also cancelled plans of launching a 4xe version of the Jeep Gladiator pickup truck and an all-electric version of the Ram 1500 pickup truck due to these same reasons. Instead, Stellantis will focus its alternative fuel powered vehicle offerings on mild hybrid and range-extended electric vehicles for the US market.[18]
A V8 powered version of the Rubicon trim level debuted for the 2021 model year. This trim goes by Rubicon 392 and produces 470 Hp horsepower and 470 lbft of torque from the 392 cuin HEMI V8 also found in Dodge's Scat Pack Charger alongside Jeep's own SRT Grand Cherokee.[19][20]
