That's the Jeep Popemobile from his visit to Ecuador a few months ago.
Apparently, there's a different Jeep Popemobile built for his visit to the US, but I don't think there are pics out of it yet. It will probably look similar though. I'm curious what shop did the build on it.
Pope Francis also used a Jeepney Popemobile in the Philippines, but I'm not sure if that counts...
These Wrangler Popemobiles are really interesting though, considering the original white, open topped Popemobile was a CJ-3B. It was used for Pope Paul VI's visit to Bombay, India in 1964:
