2015 Formula Hybrid™ Rules (Revision 2 – 10/15/2014) The Formula Hybrid trademark is owned by the Trustees of Dartmouth College Preface Welcome to the 2015 edition of the Formula Hybrid rules. You will find many changes in these rules. Most of these changes were made to increase the percentage of vehicles that arrive at the competition ready to pass tech inspection and compete in all the events. NEW! Project Management Component Formula Hybrid is universally recognized as the most difficult and challenging of all the SAE CDS competitions. Many new student teams become aware of the magnitude of this challenge late in the program, and find themselves unable to bring their projects to completion in time for the competition. This results in withdrawals, or arriving at the competition with an incomplete vehicle. Utilizing project management techniques effectively in a complex project such as Formula Hybrid will guide the team to a successful completion within the established deadline. The new Project Management component replaces the Marketing presentation, and requires two additional submissions during the year, as well as a presentation before a review board at the competition. The first submission is due in December immediately following the close of registration. We have added an introductory tutorial in Appendix K, “Application of the Project Management Method to Formula Hybrid” authored by Dr. Ed March, acting co-director of the Master of Engineering Management (MEM) program at Dartmouth. We cannot stress strongly enough the importance of each student team reading this document and applying the methods described. We can state with a great deal of confidence that those teams that utilize a structured project management process will score better at the competition than those that don’t. Formula Hybrid is planning a webinar to cover project management basics which will take place before the close of registration. Watch the Formula Hybrid announcements page http://www.formula-hybrid.org/students/announcements for details. On-Site Electrical Pre-Inspection With the assistance of volunteers from the IEEE Power Electronics Society (PELS) the first electrical safety inspections will begin three weeks before the competition at the team’s home institution. This will give teams more time to correct rules and safety issues that might be discovered by the inspectors. Changes in electrical rules. The majority of changes in the electrical rules (section EV) were drafted by the electrical tech inspectors to address what they had observed as areas of misunderstanding or confusion. We expect that you will find the rewritten rules easier to understand and to comply with. We look forward to seeing you at the competition! -The Formula Hybrid rules committee 2 © 2014 SAE International Rev. 2 - October 15, 2014 Formula Hybrid Committees -The Formula Hybrid Rules Committee: Mr. Daniel Bocci, Coppia Advanced Solutions, Inc.
