Anyone who loves a good car chase in a movie knows that the sound of an accelerating engine equals excitement. But now electric cars are more common and there’s less room for vroom, how could Mercedes make its electric EQA model sound thrilling? By installing the car in a giant jukebox alongside huge electrical coils. Electricity passing through the coils sparked an arc that created sound by heating and vibrating air molecules. With the help of AI, the jukebox was able to play 11 famous song using lightning. Visitors could scan QR codes around the installation to interact with it and find out more about the car via the WhatsApp chatbot. Needless to say, the cars sold like lightning.
