Nose and front wing look very elegant and developed. The rest of the car unfortunately is not that interesting. The hump-shaped sidepods look awkward, and I'm not so sure if they will provide optimum airflow for the rear end. Interesting mirror mountings, I expect other teams to develop that area as well.
The rear end design itself is not that interesting. It seems that they focused more on the front and central sections of the car compared to the rear. No doubt KERS has also been taking up a lot of their time. The rear passage outlet may or may not work out for them. On one hand it could provide for some turbulent air at the rear of the car making it harder for others to overtake, on the other hand it could make the rear end's balance and downforce levels inconsistent. Due to this rear outlet, the rear suspension members cannot be fully utilized for controlling airflow or possibly providing some kind of downforce since the passage disturbs the airflow somewhat.
At this stage, the F60 does not look extremely competitive but a lot can change once we're in Australia.
