From an interview with Mike Manley about the Renegade:
Can the Trail-Rated Rubicon Trailhawk manage the Rubicon Trail?
I am not so sure it will do the Rubicon, because obviously you’re talking about very extreme off-road conditions. The Cherokee, of course, went through the Rubicon, as did the Grand Cherokee and Wrangler. It may do -- I may take the opportunity to take it through there myself!
With the upgrades pictured, it might be able to handle it.
