Introduction
One of the most important considerations when designing a vehicle is aerodynamics. Aerodynamics involves how air flows past an object or how an object moves through air. The more aerodynamic a vehicle is the better your car will move through the air. We will test the aerodynamics of your car with the wind tunnel. In the wind tunnel we can see and measure how the air flows around the shape of your car. This flow of air is called streamline. A car body with an overall rounded or square shape will cause the air to stray from the streamline causing swirls of air. This turbulent air movement, called drag, will slow down the vehicle.

In this activity, you will design, construct, and test an aerodynamic vehicle. A CO2 cartridge will then power your car. Make sure you take your time and follow the limitations while building your dragster. It will have a better chance of looking good and going fast.

Problem
You are an automotive design engineer for the PCMS Automotive Company. You have been asked to design a vehicle (using the limitations in the minimum/maximum chart) that is aerodynamic, fuel efficient, and stylish. You will be in charge of the designing, constructing, and testing of the new vehicle. All the cars in the company will be compared for excellence in design, craftsmanship, aerodynamics, and the fastest racing time.
