Great time-lapse video here of the design process for the Mercedes-Benz CLS63 AMG. Enjoy!
As you will see, the video is a demonstration of the design process and not an actual work in progress. For one, the computer has obviously been set up in a conference room and, as we said, some steps are apparently skipped. Some commenters have also noted some faults in the original sketch. But as AMG says, this is a demo of how a great car like the CLS is made into a reality, and for most of the world, it is highly informative.
