P5 Phoenix


We are building a new car for Sunrayce 99: PrISUm Phoenix. The previous two vehicles used an identical aerodynamic design. Because Sunrayce 99 is a north-south race (Washington D.C. to Florida), the backwards sloping solar array used on the previous two cars will not be able to collect as much energy as a flat array. For this reason, we are designing an entirely new shape. PrISUm Phoenix is being designed from the ground up. We intend to make the body and frame of the vehicle out of lightweight carbon-fiber material. Various other concepts and designs are being worked on in every phase of the project, including mechanical systems, solar array, electrical systems, and human factors. We intend to design PrISUm Phoenix’s solar array to be lighter and more powerful than the past cars’. One of the major design areas of the vehicle is in the telemetry system. During the race, optimal strategy is a critical key to being competitive. The telemetry system will enable our team to gather data from the vehicle, including battery pack voltage, solar array output, motor temperature, and much more. This information will allow us to determine how to drive our car at its most efficient level.

Where’s it at now?

Phoenix was donated to the town of Hawkeye, Iowa during the fall of 2013. The school has plans on using the vehicle to inspire future generations in the North Fayette School District by fixing and rebuilding the car in their new technology learning center.

Sunrayce 99 – FSGP 2000

Sunrayce 99 started in Washington, D.C. and ended in Orlando Florida. The overall success of the event was limited by difficult weather conditions. Teams battled clouds and rain throughout the race, and no team avoided having to trailer their car for at least part of the race route.
