Jeep has added several new features to the 2018 Wrangler JL’s cargo to make it more functional. First, the cargo area is larger thanks to the JL’s 2.4-inch longer wheelbase. The Wrangler JL Unlimited’s cargo space now measured 31.7 cubic feet behind the second row and 72.4 cubic feet with the 60/40-split bench folded flat. That’s up from the Wrangler JK Unlimited’s 31.5 and 70.6 respective measurements. Though slight, the improvement still means more storage.
