Why Did Airbus Build The A330neo With Different Winglets?

The Airbus A330neo is built with blended Sharklets, as that is the design Airbus found best suited to the aircraft and its requirements. The wingtip device has the advantage of being the newest wingtip designed by Airbus, having drawn from its A350 blended wingtip and the Sharklets designed for the Airbus A320neo. These wingtip devices reduce induced drag from vortices generated at the wingtips and improve aerodynamic performance by around 4%.
