Ford have to find ways to make the RS cheaply not as they did with the Focus RS instaed of re programing the robots that build the car to work with the Rs bits Fit normal bits ie dummy wheels and seats then get a human to unfit them and refit them
The Focus RS WAS built as a standard 3 door Focus and then modified at an outside company by humans. BUT the wrc cars were built in batches at weekends and the robots were programmed for each body, and manually moved from machine to machine.
