The Porsche LMP1 hybrid was tested on the manufacturer's Weissach track in Germany.
The car is due to be used from 2014, and Porsche have given limited details on the technical side of their latest venture.
Fritz Enzinger, head of LMP1 at Porsche, said: "We are well on schedule. Our newly-formed team has worked with utmost concentration on getting this highly-complex vehicle on the track as soon as possible.
"This allows us a few additional weeks for more testing and further development. From 2014, the regulations are primarily based on efficiency and present us with completely new challenges."
