It might be a "Dyna Geist" or Geist Dyna by "Ernst Heinrich Geist Elektrizitäts-AG", built in Cologne around 1905-1909.
It´s been powered by an Argus or Fafnir engine that drove a dynamometer.
Each wheel of the 16 HP version had a single 110V electrical motor and it featured 4 wheel steering with two steering wheels for the two axles.
It never really made it into production, but I think it really is an interesing piece of technological history!
EDIT: I think yours is the bigger 28/32 Argus powered version.
