The process begins with hand drawn sketches with pencil and paper, and ends up on a digital screen where the dimensions, parts and textures of the future vehicle are adjusted. On the other hand, motorcycle design “is wholly carried out using digital media”, Edoardo explains to Daniel as they draw their first sketches in the SEAT facilities in Martorell.
The guidelines: When designing a motorcycle, “the rider’s body measurements” are taken into account as he will be a part of the fairing, says Edoardo. A motorcycle design is based on a drop of water, with rounded lines, compared with the harder, straighter lines of a four-wheel vehicle, where the physical characteristics of the driver are not so important.
Aerodynamics and speed: One of the keys to successful race car design is to find “the balance between aerodynamics, speed and the car’s grip on the track surface”, Daniel points out. However, on a motorcycle design, in addition to these factors, “the rider’s movements while riding the motorcycle” are analysed and prioritised, as they will determine the shape of some of the parts, replies Edoardo.
Getting a better grip: When sketching the parts of a race car, the rear spoiler plays a major role. “It’s shaped like an upside down airplane wing” to help provide the car with better grip at high speeds, says Daniel. Likewise, in order to ensure the stability of SEAT and Ducati vehicles, both brands test them in a wind tunnel to verify their aerodynamic properties.
Every millisecond counts: The SEAT Leon Cup Racer starts with a production model Leon CUPRA, which is modified. “It is 220 millimetres wider, and wheel arches, spoilers and a front end are added”, to give the car greater speed on the track. In comparison, design highlights on the Ducati Desmosedici GP include its “frame and fairing” as its essential parts.
