Co2 Car Project
Conceptual Model
Problem: Build fastest and most aerodynamic CO2 dragster
Ideas: sports car like, low to ground, pointy, smooth/rounded, thin tires, longer
Constraints: Body measurements varying from height to length, axle measurements, wheel measurements
Criteria: lightweight, low wind resistance, low to ground, rounded body/small bodied
Research: Teardrop shape + thin wheels = aerodynamic
Low to ground lets less air under the vehicle allowing more air to run over the car

Possible Solutions: make a teardrop shape with small tires and have it low to the ground for best amounts of airflow
Idea Matrix: Cone TearDrop Needle
Lightweight 1 2 3
Low to ground 2 3 1
Low Wind resistance 1 3 2
Small Bodied 1 2 3
Summary: We chose to use the teardrop shape because it can be the lowest to the ground making it less wind resistant. With small wheels and the body being low to the ground making the teardrop the best option.
