The carmaker's Hyundai Design North America studio fitted a canvas roof that can be slid forward or backward depending on your preference.
Hyundai calls the C3's roof-forward-seats-down configuration "recreation mode," allowing for bikes, surfboards or kayaks to poke out the top, Baja-bug style.
Speaking of bikes, the C3's green rear wheel is a nod to 'fixie' culture, where a contrasting back wheel is often used to broadcast that you're running a single-geared pushy.
Other mods to the C3 include a bigger grille, free-flow exhaust, bigger intake manifold, smoked tail-lights and a boot floor tiled with old skateboard decks.
Despite the exhaust and intake mods, the engine, lifted straight from the Veloster Turbo, puts out the same power.
As concepts go, this one seems unlikely to hit the market anytime soon (especially the more concept-y bits like the skateboard deck tiling), but the roll top roof idea is certainly an interesting design solution.
