This paper explains the specific measures taken to develop the body and underfloor of the newly developed Electric Vehicle for the purpose of reducing drag. Additionally, the headlamps and fenders were designed with innovative shapes to reduce wind noise that occurs near the outside mirrors. As a result of utilizing the aerodynamic advantages of an electric vehicle to maximum effect, The newly developed Electric Vehicle achieves a class-leading drag coefficient and interior quietness. The characteristic features of the upper body and underfloor of an EV were utilized to reduce the drag of the hatchback-style Nissan LEAF, while ensuring ample interior space. The car achieves a class-leading CD value of 0.29, and achieves the ZERO LIFT that is improving handling, stability and ride comfort. The distinctively styled headlamps with their upward projection from the body identify the car at a glance as the Nissan LEAF EV. Their shape also prevents disturbed airflow from striking the outside mirror housings, thereby reducing the wind noise energy produced by the mirrors by half (-3 dB) compared with a shape without the projection.
