Williams FW26

It was driven by Ralf Schumacher, Juan Pablo Montoya, Antonio Pizzonia and Marc Gené and proved to be one of the most attention-grabbing cars of the season.

[3] Head supervised the car with the aim of being on the pace immediately, whilst his design team came up with a revolutionary aerodynamics package.

It featured a short, stubby nosecone connected to the front wing by sloping vertical spars which allowed more airflow to the underside of the car.

In an effort to maximise the airflow, the front suspension was designed around the twin keel principle, pioneered by Sauber and also used by McLaren and Jordan.

He rounded off the season with a win in Brazil, whilst the returning Schumacher put in strong drives in Japan and China.
