UoP5e is the team's second electric racecar, the production of which was completed in late Spring of 2016. While a lot of its aspects are an improvement on UoP4e's various characteristics, the team made an effort to innovate as much as possible with our 6th Formula Student racecar and the result was indeed innovative. Featuring a chassis made entirely out of honeycomb alluminum panels, a unique choice among other FS teams, better driver ergonomics and impressive efficiency, while still displaying high performance on the track, the UoP5e is the result of hard work and the mentality of a pioneer. The lightweight but durable frame, along with the aerodynamic package that allows the car to run on the ceiling at 150 km/h, make the UoP5e not only a joy to drive, but also a joy to watch going around the track. The ground-breaking, fully electric powertrain provides high motor torque even in low RPMs, while the use of the aforementioned cut & fold monocoque chassis offers a sustainable yet durable and extra stiff structure, optimized to safely accommodate a wide range of drivers and also contributing in keeping Power/Weight ratio high (>500). All the above characteristics make UoP5e identifiable as a unique “weapon of joy” for the motorsport enthusiasts around the globe and at the same time make clear that electric racecars are meant to be fast, reliable and a strong competitor against I.C.E. cars.
We would like to thank the Laboratory of Manufacturing Systems & Automation (LMS) of University of Patras, as well as all of our sponsors for assisting us for yet another year in materializing our vision and making UoP5e a reality.
