I think this second type looks better on the bus than the first "737" style ones did. They look a little more fragile but at the same time more graceful.

These look really nice! Have they totally replaced the earlier large winglet design?

I'm finding it rather hard to choose which one looks better. It will also be interesting to see of the two which one will provide better fuel efficiency.

The fact that they are testing a second design now after releasing the first one for sale suggest's that there is substantially more to gain with the second.... otherwise why do it? The curvature on this one intead of the right angles on the previous one suggests there may be additional gains in airflow with the curve.

The second one in my opinion. Much more design shape!

Well, I figure that's the point of the projet. So we just have to be patient. One can figure that the desgin revision is to improve that.

Are they not testing both with an idea to pick the best?

No - its a A vs. B test. The first winglet was designed by Airbus. The second winglet was designed by an outside firm, Winglet Systems.

But the 1st set looks far better than these new paper looking things that might as well been cut by a child.

They haven't released the first for sale. This is a bake-off.

These new "curved" wingtips to me look MUCH better than the other versions we've seen. I do think it looks like a knock off of what Boeing achieved with their winglets for the NG 737's, though.

I don't know what it is, though....To me Airbus planes just don't look good with winglets. I can't explain it, but they just don't look good at all to me. I prefer Airbus planes with the fences.

I thought the second set were designed by Aviation Partners? Perhaps I was misinformed...

From the outset of the winglet programme for the A320, there were always going to be two sets: one in-house pair from Airbus, and another from an external company (which I thought was going to be Aviation Partners).

No oyu are right. The first set was designed by Airbus and the second by Aviation partners.
Actually I prefer the first set, the second ones have a nice curvy design but look to fragile and it seems that they don�t fit to the wing. It just looks odd.

Was Airbus the first manufacturer to put "winglets" on a commercial transport airplane? I still prefer the present A320 wing-tip fences. However, if the new designs provide some additional economy, go for it. Economics trump looks any day. Plus if winglets are so great, how come its not even available on the B777? Has anyone ever noticed that?

They look almost 787-ish, its the way they curve backwards I think.

I'm just guessing here but isn't the 777 really quite wide already and it would reduce the number of terminals that it can park at if it was made wider with curvy winglets - similar to the way that the A380 has little things as bigger winglets would take it outside of the 80m box

My thoughts exactly. They remind me of something you see on a concept drawing.
