The goal this year was to first build a fully functional RC car, and we could design add-ons like aero package and aesthetic casing after the vehicle validated our initial design requirements like reaching 15 ft/s under 3 seconds and less than 20% empty space on chassis plate. Though we couldn't perfect our design this year due to school transitioning to online, the end product matched all of our requirements.
Here's a video of us driving our vehicle's final iteration before school closed.
