57Univ of Illinois - ChicagoUIC Motorsportsof Cincinnati58UniversityBearcat MotorsportsThe design philosophy of our 2013 vehicle is one of simplicity, reliability and cost.All of the components of the F13 are bought or are simple enough that largescale production would still be cost effective. Our goal was to put all of theseparts together so that they would create a well-rounded, competitive vehicle thatcould be easily maintained and driven by an average racing consumer.Our vehicle will not be the lightest or most powerful car. However, with everypart we’ve carefully assembled, it will still compete with the top vehicles on andoff the track. Our design goals for the vehicle centered around designing a wellpackaged, easy to produce vehicle. It is a good stable platform that an averageweekend racer could easily maintain, race and compete with.The 2013 car from the University of Cincinnati is a cornerstone. Bearcat Motorsportshas a history of several successful years followed by learning years of therecent past. The 2012 team set a new design direction by changing car conceptfrom the 600cc engine, 13” wheel packaging to a 450cc, 10” wheel package. Aftera summer of testing and revisions, the 2013 design takes the lessons learnedand lays the foundation for a winning car concept the team will refine year afteryear. The car is a reliable test bed for instrumented testing and driver trainingcapable of directing a team with high yearly turnover into the future.To build a car to compete and continue developing of the program, our designgoals are:-Safety: Exceed minimum safety required per FSAE rules.-Reliability: Finish all events of competition, accumulate 2000 miles of tracktesting-Ease of Manufacture/ Maintenance: Tuning parameters easily adjusted andrepeatable-Efficiency of fuel, tires, and part count: Approximately 0.5 gallon fuel use inendurance-High acceleration capability: Expand driver’s friction circle to its limitsBRAKE : Fixed, opposing piston caliperBSCD : 60.0 mm bore / 42.5 mm stroke / 4 cylinder(s)/ 599 ccCOOLING : Side mounted, aluminum radiatorDRIVE : Chain with Drexler Student Formula SAEELECTRONICS : AEM EMS4ENGINE : Honda F4iFR/RR TRACK : 1295 / 1270 mmFRAME : 4130 tubular steelFUEL SYSTEM : Sequential fuel injectionFUEL TYPE : 93 octaneMATERIAL : FiberglassMPD : 10,500MPT : 9,500OLWH : 2758mm long, 1500mm wide, 1061mm highSUSPENSION : Double unequal length A-Arm.
