We’ve shown you plenty of JL Wrangler prototypes, but they’ve all been spotted on the road, so this is a bit of a special sighting, even if it’s no more revealing than previous spotting.
This camouflaged 2018 Jeep Wrangler JLU prototype was spied testing its off-road chops in Moab, Utah. You can also see that the testing team has current Wranglers on hand for comparison/benchmarking.
