The automotive industry has learned a painful lesson about the cost of developing new electric vehicles from scratch. The solution is platform reuse, and Volkswagen's new ID.Cross for Brazil is a textbook case study in how to do it right. The Economics of Platform Engineering The ID.Cross is built on VW's dedicated MEB+ platform, the same modular architecture that underpins the ID.3, ID.4, and ID.Buzz. This platform-first approach allows VW to share components and engineering costs across multiple models, reducing development time and capital expenditure. Volkswagen has already adapted the ID.3 and ID.4 for the Brazilian market, and the ID.Cross continues this strategy. The MEB+ platform is a significant evolution of the original MEB, offering improved range, charging speed, and packaging efficiency. Why Platform Reuse Matters Developing a new EV platform from scratch can cost over $2 billion and take five years. By reusing the MEB+ platform across multiple models, VW can launc...
