Jeep recently ran an add that stated the Wrangler 4XE could be used in all electric mode, full-gas mode or a hybrid combination of the two. My feeling is that’s a mistake caused by a misunderstanding in the marketing department since there’s no way to make the 4XE use only the gas fuel source. Since the vehicle is always a hybrid, a full-gas mode isn’t available. So this video explains and demonstrates why eSave is not a gas-only mode.
