How would you approach testing the aerodynamic performance of a vehicle?

Sample answer to the question

To approach testing the aerodynamic performance of a vehicle, I would start by familiarizing myself with the vehicle's design and specifications. I would then use CFD and CAD software to create a virtual model of the vehicle and simulate its airflow. I would analyze the results to identify areas of high drag or turbulence. I would also conduct wind tunnel testing to validate the CFD results and gather physical data. Based on the findings, I would make design modifications to improve the vehicle's aerodynamic performance. Throughout the testing process, I would collaborate with cross-functional teams to ensure integration with other vehicle systems. Effective communication and attention to detail are crucial to accurately collect and analyze data. I would document the testing process and findings in comprehensive reports and presentations for senior engineers and management.
