Team’s target of running a fully electric racecar for the first time in UoP Racing’s history proved to be a wise and successful decision. The members of UoP Racing Team designed and built UoP4e, despite the lack of previous background, and gained valuable knowledge and experience in electric power train. The fifth car of our team is a car which incorporates hard work and pure imagination for another step forward. This evolutionary car's highlight is the whole new electric drivetrain plus monocoque chassis design. It has a more complex geometry than our last three cars , thus achieving a 40% stiffer monocoque having a small weight penalty. Significant weight reduction was

achieved through the development of the first generation of CFRP wishbones and redesigning the unsrung mass components . Additionally, team members achieved to develop a reliable yet powerful powertrain for the first ever built electric formula student type vehicle in Greece, including cutting edge technology like Li-Po battery cells, a single P.M.A. motor and direct transmission.

UoP Racing Team competed with UoP4e in FSE 2013 (30/74/8) at Hockenheimring in Baden- W端rttemberg, Germany. For the 3rd time, our team participated in the generally acknowledged to be the best and toughest completion. The overall result of 29/40 in the electrical propulsion category is not what the team was aiming for but, despite the difficulties that team faced in Germany, the overall impression was that the car has great potential for the upcoming competitions. We achieved some great results in the FSE cost analysis event (10th place), while the team was awarded with the third place on the "Best Use of Adhesives" special award, powered by Henkel. Prior to the event, we found out that we were among the 5 finalists for the Henkel Best Use of Adhesives Award! After a small presentation to the judges of the our concept for the CFRP A-Arms and the restraining system for the battery cells, we took the 3rd place award and some very good comments for the design and the implementation of the adhesion process.

UoP Racing Team competed this year with UoP4e in Formula Electric Italy 2013 held and organized by ATA and took place on September 13 - 16, 2013 in the Varano de' Melegari Circuit. The team was extremely happy passing all inspections on the first go and having a trouble free competition, as well as with comments and general interest on our car.

Best result for us: 5th place on the Cost Analysis Event, rewarding the great efforts of the team members the whole season. However, competition organizational issues and track marshal decisions left the team with really bad impressions. The team was overly disappointed with the performance; a general feeling that we were not close to the actual car potential left a bitter taste to all team members.

Patras International Circuit for Kart took place for the 5th time in the city of Patras in the last weekend of September. UoP Racing Team participated successfully one more time, giving us the opportunity to present to the local people of Patras and international visitors the latest member of our racing family.

The UoP4e, being the first electric Formula SAE racecar designed and manufactured entirely by university students in Greece, got the attention of both visitors and presenters of the event and was cheered during some demo laps on the second day of the event.

UoP Racing Team will continue in the field of electric motorsport ,the future of motorsport, and will focus on designing and building reliable and efficient electric racecars with high performance . For the new racing season of 2013-2014 , UoP Racing Team is focused on adjusting UoP4e for the competitions Formula Student in United Kingdom and Formula Student Czech Republic in summer 2014 as well as the guidance of the new team members in designing team’s second electric racecar, UoP5e, in order to present it in Class 2 of the Formula Student competition in UK, this summer also.

Dawn of 2014 was really great for UoP Racing Team as we had a lot of fun during the teambuilding event of cutting the “Vasilopita” , a Greek version of New Year’s Pie!

News per subteam Chassis

Adhesives Technology

At this time, the team is on the design process for the new pedal box, attempting to make it more adjustable for the great variety of our drivers. Also, for the UoP5e car, the material investigation, the market search and the search for sponsorship are an ongoing task for the team. Experimental characterization of composites has also been scheduled and will be completed soon.

This season’s main targets are the manufacture of the 2nd generation of CFRP wishbones and the attempt for more extensive adhesive applications due to the lightweight benefits . At this stage the wishbones manufacturing is still in process and it is to be completed soon .

Powertrain For the new year, the Battery Management System design is almost finished and the production is ready to begin while technical documents for the competitions are under composition. Preparations for next testing are underway, in order to obtain as much info as possible for the UoP4e vehicle tuning. At the same time, each subgroup is focused on research and evaluation of the proposed solutions for every subsystem of the vehicle that will be used for the UoP5e car, including existing design and newly developed solutions. Concept design phase is almost finished and the first parts design has already started, while manufacturing of BMS test parts is being scheduled.

Marketing & Communications Significant improvement has been achieved from the members of the Marketing subteam too. As concerns the Business Plan Presentation , a new approach is decided this year with the main goal being the preparation of a “real-life� business plan. Cost Analysis is also at a very satisfactory level with the members working hard for its fulfillment. It is remarkable the fact that this year the team consists of members who are devoted only to business plan and cost analysis respectively due to the fact that this season team decided to make the best so far in static events, making use of the available manpower in a more productive way.

Suspension The outcome of the last two competitions was positive for the subteam since the suspension of UoP4e proved to be quite successful due to the properly engineered design, always keeping in mind the weight reduction. For this season the subteam focuses on data acquisition from testing periods in order to create a set of configurations that will bring the best out of the suspension system for every dynamic event. Additionally , improvements will be conducted in unsprung components in order to achieve the minimization of the camber compliance and an even better operating suspension.

For 2014, the team is focused on conducting detailed testing sessions throughout the whole season, in order to achieve the best in dynamic events for the upcoming Formula Student competitions. The overall progress of that process will allow team members to create a set of configurations of the car (regarding vehicle dynamics plus electronics control) per dynamic event, unique for every driver and optimum regarding ambient and other external factors (rain, high temperatures etc). All testing sessions so far took place on Patras Port Area (both New Patras Port and Old Patras Port were used) that Patras Port Authorities kindly provided us. We were happy, especially during winter and spring testing sessions, to test new components and verify certain aspects of car’s durability while making driver’s training realistic, as they could drive the actual car at realistic driving conditions.

Specifically, we have already tested new drivetrain parts, suspension parts, sensors and we have mainly focused on creating a new, more sophisticated and accurate power control method (including both current and voltage measurement with a fast and precise way), to avoid surprises like FSE’s DNF in Acceleration Event. We have spent quite some time on tuning our motor torque output mainly for Endurance event while the overall vehicle control concept is being under thorough testing during that period and some really good results so far. We stand now in solid ground to make the next step on vehicle setup procedure as soon as new parts arrive (especially aerodynamics package), just few weeks before the actual testing area: FSUK 2014.
