For information, to make it easier for objects to pass through the air which results in fuel consumption, the automotive industry is known as the Coefficient of Drag (CD).
The smaller the CD number of a vehicle, the maximum motion of the car will be, of course fuel efficiency. For this reason, when developing a model, the engineers took into account the body design.
With this low drag coefficient, Ioniq 6 can cover a distance of 614 km in full battery condition. In addition to increasing mileage, aerodynamic efficiency also has a significant impact on driving performance, stability and noise. To achieve this, Simon Loasby, as Hyundai head of styling, revealed a secret when designing the Ioniq 6.
“Design and aerodynamic engineering started from the 1930s, we took inspiration from that era,” he explained. He added, he was inspired by several older cars, such as the Stout Scarab (1947), Phantom Corsair (1938), and Saab Ursaab (1947) .
In addition to cars, the second world war fighter from England, namely the Supermarine Spitfire, also provided inspiration, by applying winglets on the sides of the rear spoiler.
This winglet is believed to be able to absorb airflow from the roof, and reduce drag by minimizing vortices at the top.
These winglets also serve to reduce eddy currents, generated from the sides of the vehicle, and reduce wind resistance.
Through the test results facing wind speed of 200 kph which is produced by a large 3,400 hp fan, the efficiency is 10 percent. In conducting the test, Hyundai uses Computational Fluid Dynamics (CFD) analysis, via a super computer to obtain accurate data. If, not according to the target, the manufacturer will revise certain parts.
