We've been experimenting with various aerodynamic improvements on the 70 Challenger. In order to aid our development, we've generated a rough model of the Challenger center profile to study the characteristics of airflow over the body. By creating a virtual wind tunnel with the aid of CFD simulation software, we can evaluate how changes in spoiler angle, height, and profile--for example--affect the overall lift and drag generated throughout the body. While this model only gives us a partial representation of the aerodynamic behavior of the car, it is a great starting point in evaluating how certain changes alter the pressure zones and air velocity over and under the vehicle. As we develop a more comprehensive model of the car, more and more aspects of the car's behavior at speed will be realized.
