Some of these responses have me shaking my head.
The GINA project was started when the Z8 was being developed, over 10 years ago. The point of the "concept" is to open doors on how cars are designed. The GINA concept was used to develop the Z4 and other present and future BMW cars. If you listen, Bangle says one way they use it is in design. They create a skeleton and then lay the fabric over top to see how the lines turn out. They can then adjust the skeleton on demand, and bam you have a new design and a new way of looking at design. The possibilities are endless!
It is brilliant design strategy and awesome out of the box thinking. This is how you innovate and continually keep your product fresh and provide solid direction for the future of the brand.
