Scale models-Production of models

Once the initial designs have been accepted, scale models are produced for wind tunnel testing to determine the aerodynamic values of such a design.
These models are usually constructed of wood and clay to allow for modifications to be made easily.
At the same time, design engineering personnel construct models of alternative interiors so that locations of instruments can be determined.
A  or  scale model is produced from the stylist’s drawings to enable the stylist designer to evaluate the three-dimensional aspect of the vehicle. These scale models can look convincingly real .
The clay surfaces are covered with thin coloured plastic sheet which closely resembles genuine painted metal. Bumpers, door handles and trim strips are all cleverly made-up dummies, and the windows are made of Plexiglass. The scale models are examined critically and tested. Changes to the design can be made at this stage.
