German magazine "Pitwalk" has a quite good article on the Porsche 919 Hybrid 2015 in their number 24 issue.

The main informations which include also some known ones below:

- wind tunnel change from 50% Dallara to 60% Williams F1
- new CFD-codes and changed tool chain
- first use of the brandnew full-scale Porsche wind tunnel at Weissach
- improved aero for less pitch sensitivity, more stable aero platform
- monocoque is one single piece for higher stiffness and 2kg less weight
- new batteries by A123 with higher energy density with less cells; 15 % less weight
- reworked engine installation for higher torsional rigidity
- improved bodywork for less weight and less gap width
- new lighter but also much stiffer suspension with changed geometry, FRIC still on board

- slightly increased capacity and a new smaller compressor and turbine with less inertia and changed flow geometry for better response characteristic

- seven speed gearbox with a non-stressed aluminium case, the gearbox is housed in a single piece carbon structure which include the suspension mounts

- the problems with the tyre wear and the mid-corner understeer have been solved
