WOLFSBURG, Germany - Volkswagen will show a transport van concept at the 2013 Geneva International Auto Show in March.Despite its large cargo capacity, the e-Co-Motion is compact and manoeuvrable, with carrying capacity of 800kg. What’s more, it's battery-powered.'SMALL VANS WILL RULE'Eckhard Scholz, speaking for the VW board, said: "Electric mobility – especially in light commercial vehicles – could play a crucial role in meeting the growing transport needs of the world’s megacities."Freight trains and conventional or hybrid-powered high-capacity trucks will deliver goods to the city limits then, at transfer stations, smaller biattery vans will take over. Their predictable travel routes and fixed depots would simplify battery charging and equipment maintenance."The e-Co-Motion offers good visibility and ergonomics and large doors to aid loading.The e-Co-Motion’s design differs greatly from its current models.
