It covers an area of more than 2.8 million square metres, equivalent to 400 football pitches, and produces around 400,000 cars annually. These figures correspond to the SEAT Martorell factory. But what are the specific numbers involved in making a car? Four years elapse from the initial concept until an actual car is made, but every new model always begins exactly the same way – with pencil and paper. Until settling on the final design over 1,000 sketches are drawn. In the SEAT Technical Centre, drawings take their 3D appearance in the form of clay models, which require more than 5,000 kilos to shape.
