Having applied the technical know-how from its racing program to its passenger cars, Audi is now using some of those lessons on home furnishings as well. Specifically, the luxury automaker has developed the R18 Ultra Chair. Crafted from carbon fiber and high-strength sheet aluminum, the R18 is the handiwork of digital designers Clemens Weisshaar and Reed Kram, as well as 1,500 volunteers who submitted their feedback after testing the chair at the Milan Furniture Fair in April. The designers used the resulting data and worked with engineers at the Audi Lightweight Construction Center to create a chair that weighs in at just 4.85 lbs (2.2 kilograms), embodying the principle behind Audi ultra: selecting materials intelligently and optimizing the components used. The Audi R18 Ultra Chair is on display now until December 9th at Design Miami.
