## What changed during the 2018-2025 Jeep Wrangler

| Years | What changed |
| --- | --- |
| 2018 | JL launch; note that some dealers/titles carried over 'Wrangler JK' badging into 2018 for leftover previous-generation stock, a 2018-titled Wrangler may mechanically be a JK. Confirm by VIN/generation, not just model year. |
| 2019 | eTorque mild hybrid introduced as an option on the 2.0L turbo |
| 2020 | 3.0L EcoDiesel V6 added; eTorque became optional on the 3.6L V6 |
| 2021 | 4xe plug-in hybrid and Rubicon 392 (6.4L V8) both launch |
| 2022 | New High Tide and Beach special editions added; minor equipment shuffling across trims; 4xe becomes the only Wrangler variant offered in Europe |
| 2023 | Air conditioning becomes standard on all trims; Uconnect 4 replaces Uconnect 3 with a 7-in touchscreen standard (up from 5-in); Rubicon 20th Anniversary special edition |
| 2024 | eTorque dropped from the lineup entirely |
| 2025 | 3.6L V6 automatic reportedly phased toward manual-only on some trims as Jeep leans further into the 2.0L turbo and 4xe; verify current-year trim/engine availability before ordering parts |
