What changed during the 2018–2025 Jeep Wrangler
- 2018JL 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.
- 2019eTorque mild hybrid introduced as an option on the 2.0L turbo
- 20203.0L EcoDiesel V6 added; eTorque became optional on the 3.6L V6

- 2024eTorque dropped from the lineup entirely
- 20253.6L 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
