This is a Motormouth couple car review of the 2021 Jeep Wrangler 4xe plug-in electric SUV. The Wrangler 4xe has 35km / 49 miles of EV range which is not a lot. We used most of it quite quickly so it’s important to plug-in often to see the savings at the pump. The Rubicon 4xe earns a combined city/highway rating of 4.8L/100km, 49 MPG. With the battery depleted it gets a combined city/highway rating of 11.7L/100km, 20 MPG.
