The Ford Focus WRC 2004 was a direct evolution of the 2003, lighter, more reliable, and with a smoother and more usable engine response. It incorporated minor aerodynamic and cooling refinements, and adjustments to the suspension and chassis to make it more consistent in long rallies. It did not revolutionize the concept, but it did improve overall performance and team consistency. Román Kresta and Jan Možný, driving a Ford Focus RS WRC '04 from the BP Ford World Rally Team, participated in the 2005 Corona Rally Mexico, although they were disqualified. This car served as the model for Tecnitoys' reference 6188.
