I thought you guys might enjoy this. They look pretty sweet.

 

eww ugly

What purpose do they serve?

Edit: something about fuel saving.. hope the ground vehicles dont get too close otherwise someone will have a really bad day!

Fuel consumption reduction... 

Saves another 2% apparently.

I hate them! But I also hated winglets on the 757 and 767 and later they grew on me. 

MD11 had these decades ago...what's the big deal?

I think this is a case of "monkey see - monkey do". I'm sure this is in response to Airbus putting the NEO's Sharklets on there current models calling it CEO (Current Engine Option). So naturally Boeing puts the MAX winglets/wing fence  on their current models.

From the shine on the wings, are they made of  carbon fiber? Looks similar to the look of the 787 wings.

This is an automatic message.

Not even close to being the same.

I like the Max design better, IMO

The NG's wings are aluminium, I think those on the MAX will be as well, as currently composite production processes can't sustain the production rate required for the 737, as least for large parts like the wings or fuselage. I'm not sure about the winglets though.
