Exterior Electric Hatchback Crossover Car Design with Strong, Vicious and Sharp Concept

Abstract

Identity of design of an electric car is necessary to show electrical technology and added values for consumers. Design of electic cars today, in the meaning of appearance and image, are judged by consumers as wierd and ugly compared to design of internal combustion engine (ICE) cars. The distinguished factor of electric car compared to ICE car is the technology that provides environment friendly and fuel energy crisis solution. Symbols of electric car can actually be build to be an interesting form and shape, such as smart, lightweight, efficient and clean. This research aims to design a small-medium electric car with 4-passenger car for young urban family consumer. The methods are consecutively: kind of car defining, 2D sketching, ergonomic or anthopometrical study, engineering and passenger package study, 3D styling and part design. The concept of form has adapted by keywords: strong, vicious, and sharp. Definition of ergonomic study based on Indonesian people with percentile of 5% women and 95% of men. Definition of engineering package based on Li-ion battery with size of 24 kWh placed under floor and single electric motor package placed on the front with front wheel system. The design result is a small medium crossover car with dimensions of wheelbase of 2500 mm, height of 1534 mm, front overhang of 858 mm and rear overhang of 723 mm. Design character of strong, vicious and sharp are transformed by small sharp headlamp and rear lamp; small grille with LED lines; smooth sculpting line on entire body; deep sculpting line on side body, firm and bold form of front and rear fender. The design outputs are 3D model of exterior, 3D mode; of body parts, 3D animation and physical scale model.
