It's somewhere around the weight of the 392. However, I've been reading the weight on the 4xe has some stability benefit in having a lower and balanced center of gravity.Maintenance cost? The electric system requires 0 Maintenance and carries an 80-100k mile warranty vs the 36k miles on the 3.6L. Castrated? It has more hp and torque than the 3.6L. It seems like people have no idea how a plug in hybrid works. It never HAS to be plugged in. Regenerative braking alone will keep enough charge in it in order for you to use the added benefit of the electric motors output. The 2.0t alone makes more hp and torque from 2k rpms all the way to 5600. The 3.6 has higher peak hp...all the way out at 6k rpms which your jeep will likely rarely see. Add in the electric motors ~105hp and 175 ftlbs at ANY rpms and the 4xe wins in every category from fuel economy to crawling ability to 0-60 time. The extra 500 lbs is the only drawback I see.
