Although Frozen Ever After used much of Maelstrom's infrastructure, the attraction also featured new cutting edge technology. Frozen Ever After was the first attraction to use all-electric Audio Animatronics which allowed the characters to have increased fluidity and more lifelike motion. Furthermore, like the [[Seven Dwarfs Mine Train]], the Audio Animatronics in Frozen Ever After feature projection faces, giving them a wider range of emotions. When creating these Audio Animatronics, Imagineers worked closely with the animators of Frozen to ensure that their emotions and movements were natural. When discussing the Animatronics Winter noted:
(({{Quotation|"“We really wanted guests to connect with the characters and feel like they went to Elsa’s ice palace or the frozen willow forest. It’s little things like the way Elsa crosses her arms so they are always brought together to the same place every time. This could not have been done with hydraulics."}}
