Answer 2

1. The sleek and aerodynamic design: this design features a long, narrow body with a pointed nose and minimal surface area to reduce drag and improve speed.
2. The blade design: this design features angular edges and a sharp front profile to cut through the air more efficiently.
3. The double-wing design: this design incorporates two wings on the sides of the car to generate additional downforce and stability at high speeds.
