Peugeot's i-Cockpit technology has been pushing the limits of in-car visuals since it made its debut in 2012. The Peugeot Fractal Concept aims to do the same for the audio side of things. Developed in collaboration with sound designer Amon Tobin, the Fractal is an electric car with a unique sound signature. Other audio cues help the driver to navigate the holographic head-up interface as well as the environment around them, and all these are played back through a "9.1.2" system that uses 13 speakers and bass systems built into each seat. As if that weren't enough, more than 80% of the interior trim was made using a 3D printer, getting you one step closer to downloading plans for your new car instead of going to the dealership and buying it.
