Infographic: How much clay do Ford’s design studios use each year?

Ford has offered an insight into its clay modeling processes with a series of videos and an infographic that charts the process involved in turning a designer's sketch into a full-size model. The infographic uses data taken from all of Ford's global design studios in 2012 to give an idea of how much clay is used in a year, plus how much paint and di-noc film is used to cover each model. Ford has also released a video that gives a behind-the-scenes look at the firm's clay modeling studio in Merkenich, Germany, including interviews with members of the modeling team.

Citroen DS3 Cabrio Racing arrives in the UK – just 10 at £29,305
