It's well-known that cars don't design and build themselves. Each car needs to be designed as well as created by some sort of group of creative thinkers. Let's have a look at what elements need to be considered.
Exterior
The exterior design of the car would entail the shape of the vehicle. This includes everything from the general shape of the vehicle to the type of the actual wheel arches and the small flares as well as flutes that you find upon a few vehicles. The exterior is the skin of the car. it starts out with drawings and computerized sketches. These are used to produce clay versions and finally a full dimension model.
Interior
The interior of the vehicle is where all of the luxury is. The interior will depend on the purpose of the car. A cheaper car may have much less attention paid to the inside while a sports car will have a great deal of attention paid to the layout and look of all things in a car, from the seats to the various dials on the dashboard.
Color and trim
These two areas overlap a little with the exterior as well as interior designs. It might involve choices about what materials to use and what colors would go well with each other. It might involve determining whether the car is to be a 2 toned design or perhaps a single colour. The idea is to make the car as unique as is possible within the parameters given by the objective of the car along with the designs of the interior and exterior of the car.
Graphics
The actual graphics would be the decals and dials as well as switches and that kind of thing. These are sometimes included in the color and trim section of the design however they may also be done by a separate team. All of it depends upon the budget for the design of the automobile and how elaborate things are to be.
Each one of these aspects is considered and tackled as a separate entity. They are often actually done by separate teams of designers. The design of a car isn't a short process. There are plenty of things that need to be taken into account and the end result needs to flow well.
