On the front bumper that was on all the prototypes?

 

I really don't see any change in the bumper.

 

What winglet are you talking about????

 

It's very minor. If you look on the yellow one, in front of the tire where the yellow meets black, there's an extra bit of body, triangle shaped, where the curve of the wheel well continues down.
On the red, the curve of the wheel well stops and cuts in, matching the curve of the lower bumper instead.

 

After staring for like 5 minutes -- I finally see it.

But, is it that big of a deal?

Also, the stripes on that yellow one sure look messy.

 

It has a clean look without it.
