Hyundai Curb concept

Hyundai has teased its NAIAS concept, the Curb, ahead of its official unveiling next week, where it will debut alongside a production version of the company's Veloster coupe. The Curb is a compact crossover with a coupe roofline, tapered DLO and exaggerated wheel arches reminiscent of the Nissan Juke, and is similarly difficult to judge in terms of scale from these images. While its exterior appears production feasible, the Curb's interior would seem to live up to its 'concept' billing, with extensive use of smart materials and touchscreen HMI.
