It is a larger span version of the wing raced in Melbourne. There is also an optional forward lower wing that can accompany this main beam wing. | The new beam wing options, which have a larger area than the previous version simply generate more load and drag from rear wing assembly. This gives an efficient increase in load at medium-high downforce circuits. | ![Extracted image from page 13](images/car-presentation-submissions_p13_page.png) Car Presentation – Chinese Grand Prix Stake F1 Team KICK Sauber | No. | Updated component | Primary reason for update | Geometric differences | Description | | --- | --- | --- | --- | --- | | 1 | Coke/Engine Cover | Performance - Flow Conditioning | Changes to the engine cover design. | This test item has a potentially positive effect to the flow field around the bodywork surfaces, improving both overall downforce of the car and the aero efficiency. | ![Extracted image from page 15](images/car-presentation-submissions_p15_page.png)
