Audi will unveil the A2 concept car at the Frankfurt Motor Show. Although more familiar in form than the two radically styled urban concept electric studies, the four-seat A2 concept is similarly forward-looking. Its exceptionally weight-conscious and space-efficient packaging is achieved using state-of-the-art multi-material hybrid construction, and its space-age specification includes contact-free battery charging, ‘by-wire’ steering and braking, LED matrix lighting technology and a semi-autonomous running mode.
Advanced Audi ultra-lightweight construction techniques limit the weight of this latest technology study to just 1,150kg. For the first time it unites hybrid multimaterial construction, in which very different materials are combined with one another, with the Audi Space Frame (ASF) construction principle. The superstructure is made largely from aluminium, complemented by add-on parts in Carbon Fibre-Reinforced Polymer (CFRP). The 18-inch alloy wheels also shave off around 2kg each compared with conventional equivalents thanks to cladding technology which greatly reduces the amount of material used.
