本研究旨在探討使用車身重量及車體大小變化，對電動車能源損耗多寡之影響，透過智慧型伸縮電動車實車製作測試，並套入各種實際使用情境案例作為模擬，探討其節能效益。
除了實車裝置製作與測試外，更進行了將智慧型伸縮電動車理論分析與實車裝置製作實現。從伸縮機構發想、底盤伸縮機構、車內座椅伸縮機構、擋風玻璃伸縮機構、車身伸縮機構及伸縮機構之最適化分析，一直到實車底盤製作、底盤製作與機構測試、實車車身與主要配件製作、車內座椅製作與機構測試、擋風玻璃製作與機構測試、車身製作與機構測試及外型設計與製作皆有電腦三維建模與最適化分析，最後以實車方式驗證展示。
結果顯示，智慧型伸縮電動車在車身大小作伸縮作動時，亦改變了電池配置，而電池少了重量就輕了，而智慧型伸縮電動車電池配置展開到最大時，裝載9組電池，當車身縮小至最小時，同時移除五組無需使用之電池，此時車身重量由1220 kg減少至970 kg。透過ECE-40之行車型態進行能耗測試，由實驗結果得出，前投影面積每(m2)將增加0.38 %能耗，車身重量每10 kg增加0.36 %的能耗。

The experiment is carried out by means of intelligent flexible-size electric vehicle and the actual use case can be used as a simulation to discuss its energy efficiency.
In addition to the actual vehicle production and testing, but also the wisdom of the telescopic electric vehicle theoretical analysis and real vehicle production in the paper clearly explain the show, exterior design and production are computer 3D modeling and optimization analysis, and finally to verify the way to show real car.
When the car body is reduced to the minimum, while removing the five groups without the use of the battery, then the body weight will be greatly reduced. Through the ECE-40 of the road energy consumption test, the experimental results show that the front projection area per (m2) will increase 0.38 % energy consumption, body weight per 10 ( kg) increased 0.36 % energy consumption.
