And this year, the Volkswagen California XXL isn't the only such concept camper wowing the crowds. France's Green Cat Technologies has possibly the most head-turning concept at the show with a caravan that folds out into a roomy living space complete with solar and wind power generation. The sCarabane even rotates 360 degrees at camp, tracking the sun to generate electricity and hot water.

What looks quite like a permanent, off-grid tiny home when all set up at camp is actually a folding caravan that packs neatly into a 25.6-ft-long (7.8-m-long) wheeled box via fold-down, flip-up and swing-out hardware on both sides. One side features a large outdoor deck with retractable awning, while the other side adds two bedrooms to the central living area. 

Green Cat says the sCarabane goes from living to driving form in about 30 minutes, with just one person able to do the work on their own. The caravan serves as more proof that the French are masters of this type of structural compaction, as we've previously witnessed with the Beauer 3X.
