Fun fact, the "smart" in Smart Car is a quasi-acronym for Swatch Mercedes ART. The watchmaker, Swatch, and car maker, Mercedes, worked together on the initial prototypes for the original Smart Car. When Mercedes chose not to continue pursuing making the vehicle electric and opted to go all-in on scaling up production for a gasoline-powered version instead, Nicholas G. Hayek Sr. pulled Swatch out of the project.
