EDGE9
// It's always easier!
The EDGE9 - our fourth electric car - is based on the concepts of its predecessor, with the difference that weaknesses have been eliminated and strengths have been further expanded. This season, a lot of attention was paid to improving the aerodynamics and cooling our battery pack, with the latter being implemented through new side cooling inlets. By optimizing our flaps and adding venturi tunnels to the side, driving stability at higher speeds has been improved. Since we were able to achieve a weight saving again this year compared to the previous year, we were able to improve our top speed again.
