It became a so distinctive part of modern sportscars that is actually weird to watch a finless 908 HDi or lola-aston.

Anyway, by the pics, to me is quite clear that is a standard oreca 07 with a customized acura front section.

Wonder if a nissan dpi developes more or less front downforce compared to a standard ligier. The same about cadillac dpi that however has a more revised aero compared to a standard dallara.

Cadillac is definitely higher downforce, this probably is as well, and I imagine the Nissan is roughly neutral. Nothing to do with the dumb panel, they just have what would tend to be interpreted as a higher downforce fender shape. (that's about all they have, either) Probably not a major R&D project so much as the manufacturers pulling out a fender shape they already ran in the wind tunnel and rejected for WEC/ELMS tracks.
