  Kiepe Electrik  
New trolleybus overhead current collector design.

  Irisbus Civis -  
Available as a trolleybus, with central driver position (above) or offset.

  Civis optical guidance -  
Mounted at the base of the windscreen, a camera reads pale blue, road painted, dotted lines to provide an optional guidance system. The idea is currently being tested at Clermond-Ferrand and Rouen in France.

  Civis axles -  
Hub mounted motors on the two rear axles, turning special 'super-single' tyres, provide a low platform height of 320mm.
