P12 Phaëton
Introduction
Phaeton 2 was built off the frame and shell of Phaeton, the team’s 12th solar vehicle. Due to the long term goal set of competing in the 2017 Bridgestone World Solar Challenge, PrISUm decided to rebuild Phaeton instead of constructing a new vehicle from the ground up. In order to make the car competitive for the 2016 circuit, the vehicle was completely stripped to bare carbon fiber and rebuilt with new electronics, suspension, and fairings. Due to this effort, the team was able to increase the aerodynamics of the vehicle, increase the battery capacity, and increase the motor efficiency. This came at a slight cost, as the project was finished just in time to ship to the Formula Sun Grand Prix. The minimally tested vehicle had reliability issues that caused delays during the race. These delays, coupled with bad weather, made for a race to remember for all who attended.Media

Where is it now?
On November 5th of 2017, PrISUm said farewell-for-now to Phaeton as she continues her journey as one of the most successful solar race cars to ever come out of our team. Similar to the donation of Hyperion’s shell and chassis to Appalachian State University, Phaeton was donated to the University of Iowa Society of Mechanical Engineers to kick-start their solar car program.The donation of Phaeton’s structure and body acted as a significant head-start on designing and racing U of I’s first solar car in a number of years. Moving forward PrISUm will continue to mentor that team as they continue to design all electrical and mechanical systems for Phaeton’s new life. Their plan is to take Phaeton on a tour of Iowa to grow awareness of their program and also as a fundraiser with the hopes of competing her in the next Formula Sun Gran Prix.

The 2016 Formula Sun Grand Prix was held at the Pittsburgh International Race Complex in Pittsburgh, Pennsylvania. When PrISUm arrived, they noted that the top speed of the vehicle was severely lacking, topping out at 45 mph. In order to increase this speed, members began the designs of what became a Turbo-encabulator. Thanks to the help of Rockwell Collins engineers Steve Goode and Bryan McCoy, the team designed, tested, and built a boost-voltage system at the track. This system allowed the battery pack voltage to be increased from 86V to 110V. This higher voltage allowed the motor to spin at a higher speed, pushing Phaeton to speeds of 60 mph.
