Porsche has unveiled the 2015 919 Hybrid in Weissach, Germany.

The company was coy on details but said the model is more "significantly developed" than its predecessor. That's not much to go on but the company has previously said it's a "distinct evolution of the 2014 model" and has been "optimized in almost every detail."

Porsche also said the car will be better able to adapt to the different characteristics of the various race tracks in the 2015 World Endurance Championship.

In a statement, Porsche LMP1 Technical Director Alexander Hitzinger said, "The roll-out of a new race car is always a milestone, and anticipated with great excitement by everyone involved. It was our target to get the Porsche 919 Hybrid for the 2015 season on its wheels before Christmas, and now we have achieved this.”
