2.0 INTRODUCTION2.1Target MarketThis racing car is a kind of car toys. This kind of product is suitable for those 3 years old and above especially to others from all corners of this world who shares the same passion and spirit of Tamiya. Tamiya produces components for moving toys and models which are like their fun-to-build series and also makes kits to make simple robots. The metal molds were produced from plans which had the concept of being easy to understand and build, even for beginners. Even the box art was consistent with this throughout the company. In the same vein as everybody being able to build the models, they made the parts accurate and with a high degree of detail. The company has gained a reputation among hobbyists of producing models of outstanding quality and accurate scale detail.

2.2PRODUCT HISTORYIt all started in 1946, when Mr. Yoshio Tamiya, the founder, opened a saw mill and lumber business in Shizuoka. Tamiya ventured into modeling in 1948, with a scale wooden ship model kit. Since then, Tamiya has continued to grow, producing models known as "First in Quality Around the World".Then in 1948, a wooden model department is organized within the lumber company. After that, in June 1953, Sawmill is closed and Tamiya becomes a specialized wooden model kit maker. After all, in December 1962, the Tamiya Plastic Kogyo Co. is founded as a plastic molding company with a capital of 4 million yen. In May 1966, Tamiya ventures outside of Japan by exporting to countries abroad, such as the U.S.A., Australia, Europe and South East Asia. Jan 1967, the first issue of Tamiya News is published. Aug in the same year, the first issue of Tamiya Junior News is published. The Tamiya Plastic Kogyo Co. is renamed the Tamiya Plastic Model Co., and capital increased to 14 million yen in August 1969. In Nov 1977, a shipping facility is completed next to the production factory. Tamiya's first R/C Racing Circuit is completed. Time to time until 1985 somewhere in March, the first issue of Tamiya Model Magazine International is published and then in November in the same year, Tamiya Plastic Co. Ltd. completes its own injection molding factory. 1989 May, Tamiya America, Inc. is established in California, U.S.A. and a month later , Tamiya Europe GmbH. is established in Neuss, West Germany.

3.0 REASON FOR CHOOSING THE SPECIFIC PRODUCTThe main reason why we choose this car is so that we can study and make improvement that can be applied to real car using miniature model which is less expensive and less costly to be used in this study. As we all know miniature model can be made up to scale so that it can replicate the physical,dynamic and durability of a real car, this enables researchers to study the many properties that make a car good. Furthermore, this method had already been used in the real automotive world.Other than that, we can also study the effects of weight distribution on the overall performance of the car. This is vital due to the fact that weight distribution affects many of cars driving properties. To achieve this perfect weight distribution that many car makers desire extensive study have to be made and one means of it is by using miniature model which have similar component as a real car would.Finally the reason as to why we choose this miniature car model (in this case Tamiya) to be the basis of our project is so that we can study the complexity and the many parts that is required to build up a single car. As we all know car which is an end product is made up of many components and parts, this parts and components is mass produced by using machinery and automated assembly line. However, since it is mass produced we have to make sure that the parts and components are made to the specific measurement and dimension, this is made possible by using Computer Aided Design software such as catia

5.0PRODUCT IMPROVEMENT AND MODIFICATIONSIn the engineering field we are constantly re-inventing and re-innovating a certain product so that it will still be relevant and usable in this ever changing environment. The automobile and car is no exception. From this study we are able to make improvement and enhancement to the current automobile which can be beneficial to the automobile industry as a whole.

One improvement that can be made is to improve the aerodynamic properties of the car. This can be made possible by the fitting cars with a diffuser, skirting and more aerodynamically efficient body styling. The effects aerodynamic have on the overall performance of the car is significantly big. It can affect the fuel consumption, driving properties and also performance of the car. Hence the one of the improvement that can be made is through better aerodynamic properties.

Another improvement that can be made is by using better and more rigid chassis that can withstand the most demanding of situation. Since chassis is the main skeleton or backbone of the car, chassis design and rigidity must be improve so that safer and better car can be produced.

Besides that, we can also improve upon the current engine of the car, as we all know the environment is becoming more and more polluted and the need to build a more greener and environmentally friendly vehicle is becoming more and more important as can be seen by many automakers shifting towards building hybrid cars which is more environmentally friendly and economical.

As stated those are some of the improvement and enhancement that can be made to current car that can be beneficial in the long run.
