My gut recation to that new nose is that it aims to get more air under the nose than above it.
Possibly to the floor, but I don't want to jump on the "Aha! it MUST be for the diffuser!" bandwagon (as if that's the only thing any upgrade on an F1 car is designed to work with) Its equally plausible that the aim is to get air under the nose and to the splitter and around the sidepods.
EDIT: Having looked again, now I'm not so sure, at first it looked higher...now it looks lower than the old nose. I dunno! lol
Silence is golden when you don't know a good answer.
