I guess we might have already seen changes No. 1 and 2.. but the winglets (3) should be new.

It may be me but I am failing to see any real changes to the rear wing except for the angle.

It may be me but I am failing to see any real changes to the rear wing except for the angle.

I meant the diffuser winglets (well, difusser shaped like winglets) on its sides - number 3 on the picture above. Rear wing did not change (unless I am not mistaken).

I was making a general statement, it was not related to your post. Thanks for all of the pics and info!!! @BAR as well!
