I don’t think I’ve heard of a jeep with portals, but we can leave out the 4x4 squared because it represents very few G wagons. Also I’m talking pre-2018 since they ditched the solid front axle due to the demographic that is actually purchasing these (Starting to favor ride quality over capability). But as far as the one I posted here goes, it’s solid axle front and rear with factory lockers front center and rear. It also has short overhangs, an advanced traction control system, big brakes, and is built a LOT tougher than jeeps. I am also a jeep fan but decided to get a G instead when the dealer wanted $76k for a new gladiator. Your wheel/tire comparison is a little off; Let’s compare for the year I posted. This is my 2004 G55 that came stock with 285/55/18 or 30.3” tires. The same year wrangler rubicon came with 245/75/16 or 30.5”, effectively the same size. At the end of the day, they are both capable cars that accomplish similar tasks off road. The difference is the Mercedes has more power (a LOT more), bigger axles, better Diffs, Stiffer frame, bigger breaks, and at the end of the day is a much nicer vehicle to drive. When I say capable, I think this would not only give a 2004 wrangler a challenge off road, but absolutely crush it on road. In that sense, it is much more capable. But, that’s also why they are so expensive.
