Most 4 bangers can't even use the fast lane on the freeway. They do fine in the trails though, not as well in the mud or sand, but they get it done.
the 2.5L is way over-worked in a 3300 lb Wrangler. I think that is a big part of their durability issues over a 4.0L.
I had a 2.5L once. It was such a turd I put a turbo on it. Never again for me.
