The C-Max uses the platform of the new generation of Focuses. The Mazda3 and the new Volvo S40/V50 also use the same platform. Ford is able to build both Focus and C-Max on the same production line in Saarlouis, up to a 50-50 ratio, which, once the full capacity is reached, would correspond with 900 units per day of both Focus and C-Max.
Ford developed the seating system of the five-seater in a joint venture with Johnson Controls. The middle back seat can be folded away. The outer seats can then be moved diagonally toward the center.
