Evoking speed and entirely made of aluminum, the chassis of the Racing Symphony was painted in several vibrant colors by a coachbuilder, just like racing cars. These colors represent the competing nations of the time: red for Italy, blue for France, green for the United Kingdom, and yellow for Belgium.
To enhance the resemblance to a real sports car, REUGE placed two independent symmetrical movements inside an automaton, inspired by the 16-cylinder engine of the 1930s Auto Union series. The air intake on each side of the sports car houses another moving component, the flying wheels. Their role, in this case, is not to cool the engine but to regulate the rotation of each cylinder to achieve the desired musical rhythm. As a mechanical automaton, the energy required to operate its movements is generated manually using a carbon steel winding key. The two independent movements are equipped with two barrels located in the cockpit, and their main springs can be wound using the key through the two exhaust pipes.
