Competition Objective
To challenge teams of university students to conceive, design, fabricate, develop, and compete with small, formula-style hybrid-powered cars.
The formula hybrid competition is intended as an educational program requiring students to work across disciplinary boundaries.
To allow teams to freely express design, engineering, and imagination.
Teams are allowed eight to twelve month to design, build, and test for the competition.

What is a Hybrid?
4
Series Hybrid System Layout
Parallel Hybrid System Layout
Energy flows in 2 parallel paths from reservoirs to the wheels.
Energy flows in one path from reservoir, through all components, and finally to the wheels.
Design Outlook
5
Both Parallel and Series configuration have different advantages and disadvantages. This is why we plan to implement a design that has the ability to switch between the two. In theory, this should achieve the
best of both worlds.

All of these device are used to increase the downforce on the vehicle by manipulating the air flow.
Conceptual Design of Body
These are the top three teams who scored the highest in the design category.
Expectation for our project is for it to be unique and marketable.
