I have my doubts that the MP 4/23 of 2008, designed by Tim Goss and Simon Lacey, was really based on a design Newey had made ten years earlier for the MP 4/13, especially considering there had been quite a few changes of the regulations in the intervening years (including a reduction the size of the rear diffusor in 2005).
