No End To Perfection.
The Beginning.
Our inspiration came from our excellent and well-tested regionals car. We took several things we have learned to help with aerodynamics and put them together to form our regionals car. The drag force for the regionals car was 0.308N @ 20m/s.
Early Designs.
Our earliest designs took great inspiration from our regionals car by enhancing traits that made our regionals car fast. The channel underneath the car was enlargened to a large degree, and the shapes of the side pods was based on the regionals car. We also made smaller wheels to create a smaller profile, which was found to reduce drag with our regionals car. The drag force was 0.239N @ 20m/s.
Tested Car.
We tested this car on the track to test two aerofoil designs. There were a few changes, with the biggest change being the rear pods, which were extremely efficient. The drag force was 0.235N @ 20m/s.
Another Aerofoil.
We tested this aerofoil against the aerofoil on the test car. It did not perform as well and the car was significantly slower.
Final Car.
Changing the side pods back to the side pods in our early designs proved to have a large impact on aerodynamics. The side pods direct air above the wheels, which reduces the size of the vortex created. The drag force was 0.216N @ 20m/s.
