Swiss company Rinspeed introduced Snap at CES 2018—a vehicle in which the chassis (Skateboards) and bodies (Pods) can be swapped out at any time. For CES 2019, the company has shrunk the Snap into the microSNAP, which has the dimensions of a Renault Twizy, and the company is demonstrating a fully automated robot station that joins and separates chassis and bodies autonomously.
The concept behind Snap and microSNAP is the same, according to the company: While the bodies last as long as a car does today, the chassis contains all the components that are subject to wear and aging, such as the computer technology for autonomous driving. Skateboards and Pods are only temporary companions for brief periods. Various types of bodies use whatever skateboards are currently available. The skateboards are recycled after a few years, because they will have reached the end of their service life. In this way they avoid an expensive and complicated hardware update.
