2005年臺灣車壇一大盛事－裕隆汽車正式推出新品牌納智捷，臺灣汽車產業也由製造端推進為品牌設計端。汽車業歷年來經過幾次金融風暴與汽車集團併購案後，原本各具獨特風格的設計品牌，因需共用平臺以降低成本之條件下，全球汽車外觀造形風格因此而有相似的窘境。一直到BMW造形設計團隊改變汽車車側造形設計，將車側車身設計概念，由流暢平順演變為飽滿且凹凸有致的造形。因此，本研究在全球汽車銷售市場裡，選擇競爭最為激烈的C級距車型，進行設計相關性的探討，對於當受相關限制條件的要求時，車側設計與相對汽車部品之間設計關係、是否受汽車公司品牌統一識別的設計限制、是否受全球同等級距汽車車側的設計影響等問題點進行探討。
本研究主要以汽車業界專家訪談的方式，探討臺灣C級距車之車側造形設計的演變等相關議題。歸納本研究結果發現：
1.各汽車廠尋找或延續屬於自己車側的造形定位。
2.汽車造形部門主管對於車側造形趨勢方向，具有決定性的影響力。
3.汽車車側造形設計風格，有因應品牌全球化的趨勢。
4.西方與東方汽車設計美學，有相當大的不同。

2005 marked the beginning of a new automotive brand by Yulon Motor in Taiwan- Luxgen. The Taiwan automotive industry was advanced from manufacturing to brand design. After the worldwide automotive industry has suffered several financial storms and mergers involving several major car companies, unique design brands was found to share similarity with car appearance under the condition of sharing platforms to reduce cost. It was until the change of profile design by the design team of BMW that transformed the design concept of car profile from fluent and smooth to plump and bulgy shape. Therefore, this research selected the C-segment cars that were fiercely competed in the world automotive market for a study in design relevance. Under the requirement of relevant constraints, several issues were explored including the relationship between profile design and car components, the effect of car companies’ brand identities, and the global influence of profile design on the same segment.

Interviews with car experts were used in this research to explore relevant issues on the development of the profile design of Taiwan C-segment cars. The results of this research were as follows.
1.Each car company tried to locate or continue individual positioning of car
profiles.
2.Design directors of car styling departments were decisive in the trend of
profile design.
3.The style of car profile design was accustomed to the globalization of brands.
4.There was a major difference in design aesthetics between the West and the
East.
