As I can see the little wings have a very short chord.And the top little wing seem to touch the bottom of the full-span wing.How can such as short chord wing produce a meaningful amount of downforce? or is it there just to condition the airflow by accelerating the air that pass under the main wing and hence increase the downforce of the main wing?
About the lower wing I think it could be to avoid pitch sensitivity problems as it happened in previous examples (i.e. Benetton B201). The wing is probably at the minimum allowed height (50 mm above RP AFAIK), so the ground clearance is probably about 7-8 cm. In a few studies about wings in ground effect that I’ve seen (although they were obviously about isolated wings) the critical ground clearance (when the wing stalls) is around 20-30% of the chord, so a chord longer than, say, 10 cm, could have some problems. That in theory, obviously.

There are two versions thy are running in tests right now, one is a modified F2003GA, the other a F2004.
Really? which photo shows this??
F2004M is obviously a modified F2004.

Luca used actually a F2003GA last week in Fiorano during a meeting with about 50 Italians athletes who won medals in Athens, but I read that it was also planned some tests on electronics, don’t know if that same day or the following one.
