CO2 Dragsters
You are a car designer who runs a small business designing racecars. There are some major sponsor’s who
have shown interest in your business as possibly designing dragsters for the up and coming race season.
To prove yourself as a competent designer you must design a vehicle, which will compete against other
designers. You must keep good records of the complete design process to present to the sponsors, build
and test a prototype and race your competition.
Thumbnails 30 points
8 drawings that will illustrate different ideas you have in the design of
your vehicle
Rough Renderings 30 points
3 drawings to filter down the many ideas of the dragster
Final Drawing 100 points
The final idea. This will be the vehicle you will make.
