City :) (City Fun)

The City :)™, pronounced City Fun™, represents the first attempt to create an Electric Micro City Car™ (E=MC²™) with contemporary design and technologies by us from Style of Speed as part of our definiton of the Sustainable Electric Mobility™, inclusive Electric Micro Cars™.

Technically, the City :)™ is based on our Just 4 :)™, but configured as a commuter with a 1+1 seat configuration, as it is know from smaller air vehicles. The optional rear seat can be easily taken out through the trunk door for creating a large trunk for the easy trans- port of items, like:

  • luggage,
  • medium-sized kitchen machines, refrigerators and washers,
  • baby buggy,
  • wheel chair, or
  • one of our bicycles, e.g. an electric bicycle.

    The split trunk/boot door makes it also suitable to transport larger objects.

    The interior optionally features the full spectrum of contemporary devices, like our:

  • on-board computer powered by our Hightech Operating System™ (HOS) OntoLinux™,
  • multi-touch P@d™ as the easy to understand user interface for the manual and the digital handling elements,
  • exclusive Car-X Window System™,
  • fully customizable Graphic User Interface (GUI) for easy handling and individualization,
  • optional Multimodal Multimedia User Interface (M²UI™),
  • Hyper Connectivity™ comprising
    • World Wide Web,
    • AutoCloud™/Car in the Cloud™ based on the Castle in the Cloud™ system

      with the applications

    • MapCloud™ based on a positioning/navigation system, and one or more online street maps,
    • AutoMapCloud™ based on MapCloud™ and the Active Cam™ technology, and
    • MediaStreaming, e.g. iCloud,

    as well as the further options

  • Active Interior™ components,
  • Active City Assist™ (ACA) package, and
  • Swarming™, our Swarm Intelligence System™ (SIS).
