Images: Boeing introduces new dual tip winglets. A throwback to the MD-11?

US airframer Boeing unveiled a new dual winglet design concept for the 737 MAX.

The new Advanced Technology winglet is expected to provide an additional 1.5% fuel-burn improvement, on top of the 10-12 percent improvement already offered on the new-engine variant. Compared to today’s wingtip technology, which provides up to a 4 percent fuel-burn advantage at long ranges, the Advanced Technology winglet provides a total fuel-burn improvement of up to 5.5 percent on the same long routes.

In a way the new winglet design reminds one of the venerable McDonnell Douglas MD-11 which is now owned by Boeing.
