Videos: Volkswagen's exterior and interior designers highlight the Up's design elements

We've enjoyed the design of Volkswagen's new Up since we first saw the vehicle in concept form at the 2007 Frankfurt motor show. Devoid of any extraneous detailing, the simple, product design aesthetic is pared back to represent the crux of VW's design philosophy: pure, simple and solid.  The result is a harmonious design that stands out from the pack, with simple surfacing and subtle detailing; the Up's design is pure and minimalistic, which serves to exude quality in the product. Inside, the vehicle is brimming with space-saving design details.  From an IP devoid of central air vents to a thin headrest that visually extends the height of the interior, the Up is a success story in space efficiency, but it is also finished to a high level using quality materials.
