In terms of manufacturing steps, your plant is comparable to a real car factory. What have been the technological evolutions over the last 20 years?

The biggest progress has been made in the development process. Twenty years ago, we developed a miniature prototype 100 percent manually; we sculpted the shapes in a block of plaster. Today, however, 98 percent of the projects are developed in 3D, with 3D files that either come directly from manufacturers or that we create ourselves in France with a 3D scanner and a team that recomposes 3D files. It saves time and allows for precision. It's not necessarily cheaper, but it is more efficient.

Are you interested in electric cars? Does Spark manufacture electric car models?

A car is a car, but I have big doubts because I have an ecological problem with the electric car. An electric car, once recycled, becomes the most polluting car in the world-and the production of electricity to charge the batteries also causes huge amounts of pollution.
