Sahara 4xe / Rubicon 4xe (JL PHEV, 2021–present)
Monitor

The Wrangler 4xe is the plug-in hybrid JL — 22 miles all-electric range in a capable off-roader. The hybrid system adds significant weight and complexity. Early production had multiple electrical recalls. The PHEV battery adds to the Wrangler's already-high purchase and maintenance costs. Strong buy for buyers who want off-road capability plus commute-friendly EV range, but verify all recalls are closed — there were many on early 4xe builds.
