Tesla Model Y

Tesla releases first Model Y production picture, hints at body manufacturing breakthrough - Electrek



"In an interview last year, CEO Elon Musk said that Tesla is moving to an aluminum casting design instead of a series of stamped steel and aluminum pieces for the Model Y body:

When we get the big casting machine, it’ll go from 70 parts to 1 with a significant reduction in capital expenditure on all the robots to put those parts together.

The automaker has designed a giant new machine to be able to produce vehicle frames in almost one piece."
