"ID5" refers to two main things: ID5.io, a digital advertising identity provider building privacy-focused user recognition tools, and the Volkswagen ID.5, a sleek, all-electric coupe SUV known for its style, comfort, and advanced tech like the panoramic sunroof and driver assists. While one deals with online data and the other with electric cars, both focus on modern solutions, with ID5.io addressing cookie-less identity and VW tackling sustainable personal transport.
