Though distinct classes of vehicle have always been designed with particular uses in mind, such as off-road vehicles, sports cars or the distinctive London taxi, they still have basic features in common. There’s nothing to stop you going on vacation in a Smart, or just popping down the road in a Hummer, for instance. However, as electromobility takes off, widely diverging trends might emerge. The current range limitations of battery-powered vehicles are almost bound to give birth to a species that is dedicated to local transportation – restricted in the range they can cover, but perfectly tuned to their urban environment. This is precisely the idea behind the ACM (Adaptive City Mobility) concept and its "CITY eTAXI", which the Green City Project is showcasing in Hannover.
The ACM Project is part-funded by the Federal Ministry for Economic Affairs and Energy with the aim of making electromobility "competitive and resource- and environment-friendly". The first tangible outcome is the "CITY eTAXI", an all-electric, four-wheeled light vehicle (550 kilograms, class L7e) designed exclusively for urban use. Visitors to CeBIT can take a close look at the first road-ready show car before it drives off in real traffic later in 2017. The attractively styled electric car has three seats, with the two in the rear smartly removable to offer 360 liters’ storage capacity. The "CITY eTAXI" can drive at speeds up to 90 kilometers per hour, which is more than enough in city traffic. A set of six battery modules achieves a range of 120 to 160 kilometers. A full charge takes about three hours at a high-speed charging station, or six hours if plugged in at home. ACM believes its concept paves the way for an extensive electromobility system in future that would link e-cars equipped with a battery-exchange system with battery exchange stations, operators, energy suppliers and end consumers.
