These days,cars are designed using computers．Let's look at how a new car is created．
　　First,several desighers talk about the new car and any good ideas that they have．Then they sit down at their computers and draw many sketches．The best two or three drawings are chosen and then more detailed drawings of cars are developed on the computer．You can change the size,shape or colour of any part on the computer to see how the car would look and then you can choose the best design．
　　Both the inside and the outside of the car have to be designed．Part of the inside of the car is built so that the designers can sit in it．They can feel if there is enough room inside and if they can reach everybody．Then some cars are built-there are more than 15,000 parts of a car to test．
　　When everything is known to be safe,the cars are made in the factory．Again,computers are used to make sure that all the parts are ready as they are needed．The factory
　　usually stays open all through the night so that the car production never stops．
