The Dock+Go concept is based around an electric runabout built on the diminuitive SMART ForTwo platform. As the concept suggests, dockable rear extensions are tacked on to the main car to extend its usefulness. These include an insulated pizza delivery, a cargo, and a dockable Harman audio sound station.
More interestingly, since the Dock+Go is electric, these backpacks open up the possibility of swappable range extenders. The base vehicle’s small battery pack is big enough for short-distance commuting, but for long-distance driving, a Variohybrid backpack with additional battery space help extend the vehicle's range.
Better yet, the Variohybrid pack can be combined with other packs, making the Dock+Go more useful and flexible. Besides the backpacks, the Dock+Go also features such tech-heavy features as temperature regulating fabrics and synthetics, an intelligent user interface with advanced connectivity, inductive battery charging, and lightweight composite construction.
While the chances of this concept becoming a production model are remote, it will be interesting to see what influence it has on electric vehicles of the future.
