Yes, Grobmotorix got the right car! The picture shows an Austro-Daimler Mixte 1908 driven by Otto Kaes. My source says it was called typ Taunus because of the fact it took part in Taunus Renn.
I'm quite sure that the electric engine was provided by Porsche who entered in Austro-Daimler in 1907, so it's probably it was a Lohner engine.
I think Grobmotorix deserves this point.
