Since McLaren Automotive Ltd<\/a> revealed the Elva, I have been impressed by its design. Instead of a traditional windshield, the Elva uses AAMS (active air management system), located in the nose of the car, which creates a region of calm air for the passengers.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

I decided to test its performance by creating a CAD model and carrying out a CFD simulation on SimScale<\/a>. In addition, I tested the Elva with a windshield instead of the AAMS to see how different the Elva is to a regular convertible (at 100km\/h).<\/p>\n\n\n\n

My simulation validates 3 points:<\/p>\n\n\n\n

1. The AAMS manages to create a region of very slow air, and thus has the same effect as a windshield.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

2. Compared to a windshield, the AAMS increases drag and downforce. Drag increases as the airflow gets more disturbed, but the increase in downforce remains interesting.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

3. I discovered that convertibles suffer from a very slight cabin depression that depends on the speed of the car. It is a natural phenomenon that occurs as a result of the high speed air passing over the body of the car. Thank you to Jamie Fox<\/a> for clarifying this point.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

This study has been especially interesting as the Elva is a new take on open-top cars. The remaining point that I would like to investigate is the increase in downforce for the Elva with the AAMS.<\/p>\n\n\n\n
