The automatic transmission made its debut in the 2018 Jeep Grand Cherokee (WK2), replacing the older Torqueflite 845RE unit.

The new engine features an optional mild hybrid system branded as eTorque for improved fuel economy and off-road performance.

Paired exclusively with the 850RE Torqueflite eight-speed automatic transmission and including the eTorque system, the engine produces 270 hp (201 kW; 274 PS) and 295 lb⋅ft (400 N⋅m) combined.

[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 (149 kW; 203 PS) and 450 N⋅m (332 lb⋅ft) with Start&Stop is available.

[14] It uses a 17 kWh (61 MJ) lithium-ion battery pack that gives it an EPA-estimated range of 21 miles (34 km) and an EPA-rated 49 MPGe.

This trim goes by Rubicon 392 and produces 470 hp (350 kW; 477 PS) horsepower and 470 lb⋅ft (637 N⋅m) of torque from the 392 cu in (6.4 L) HEMI V8 also found in Dodge's Scat Pack Charger alongside Jeep's own SRT Grand Cherokee.

The Uconnect 4C 8.4N system is only available on the uplevel Sahara and Rubicon models when equipped with the Electronic Infotainment II Group.

All three infotainment systems include a fully integrated and federally mandated rear-view backup camera as standard equipment.

There is a new three-spoke, retro-inspired steering wheel, and a color instrument cluster display screen is available on upper-level trims.

[21] In 2020, a 4-door JL Wrangler Unlimited overturned upon impact with the rigid barrier during the IIHS's 40-mph small overlap test.

Despite claims from Jeep that the JL Wrangler's structure was modified to prevent the same outcome, the vehicle overturned again during a retest for the 2022 model, despite some minor suspension changes, resulting in another "Marginal" rating.

[27] The plant which produced the JK will temporarily close as it receives a retooling for the upcoming Wrangler-based Jeep Gladiator.

[28] FCA announced that the Toledo Machining Plant would assemble the power electronics module and components for the Jeep Wrangler Plug-in Hybrid which was intended to be launched in 2020, but was actually presented in 2021.

[29] Before the JL's actual debut at the 2017 Los Angeles Auto Show, the song Believer by Imagine Dragons was used in the opening.

[30] In the teaser, it uses 7 letters that are narrowed to represent the 7 vertical slots and 2 circles on the left and right to depict the front fascia.

A debut television advertisement for the 2018 Wrangler JL, entitled "Jeep Jurassic", first aired during Super Bowl LII.

The center stack is redesigned to accept the larger touchscreen, which removes the genuine metal dashboard trim, as well as replaces the previous round air vents with horizontal rectangular units.

The previous 3.0L EcoDiesel turbocharged diesel V6 engine has been discontinued for 2024, although remains an option on the related Jeep Gladiator (JT).
