We're a little non-plussed on Porsche's announcement of a reconstructed Semper Vivus, which it is claiming was presented at the Paris Show of 1900. There's a video of the construction of the vehicle, but it is at odds with previous Porsche historic information on the Lohner Porsche and the normally fastidious Porsche press department hasn't issued any details of the Semper Vivus.

The Semper Vivus was a series electric hybrid with its two engines charging the batteries and Porsche electric hub motors delivering the power. More details as they come to hand, though an excellent photo gallery in the meantime.
