Ford unveiled a new assembly line on Monday, which CEO Jim Farley called the most radical change at Ford "since the Model T."

I’m always saying that if a gap in the market is obvious to one OEM, it’s obvious to all of them. Generally, if a manufacturer comes out with a segment-busting new model that sells like gangbusters, their rivals usually sit up and take notice.

In what CEO Jim Farley called a 'Model T moment,' the company that popularized assembly lines is turning in a new direction for electric vehicles.
