Taking a car model into a wind tunnel is an chance to test digital designs in the physical world. But the work doesn't stop there. Information gathered can have a huge influence on the vehicles final form. Episode five of ""From Concept to Car"", details the aerodynamic testing of Polestar Precept. Discover the near future of automotive: https://www.polestar.com/global/precept/ Polestar Vehicle Development Chief Engineer Eddie Martin and his team tell of the importance of testing a new electric car in the wind tunnel, and how it influences the eventual exterior design of the vehicle. Wind tunnnel tests are carried out at multiple stages during the design process to test the car for aerodynamic issues such as air resistance, lift, and other factors. Throughout its development, Polestar Precept will go through four rounds of wind tunnel testing, each time with a new model redesigned and built on past results. Polestar Precept concept will be brought to production as Polestar 5, set to be launched in 2024.
