Info
After 6 years in the Formula Student Electric Deefholt Dynamics e.V. is back in the combustion class. The design process was started in January, so the race car was built up from nothing in just 6 months of time. This would not have been possible without the support of our sponsors and the help of all the other Formula Student we contacted. Thank you!

Info
The Racing Team of the FHWT Diepholz (University of Applied Sciences for Economy and Mechanics) was founded in September 2005. It constitutes a part of project studies, where students have to realize a design project from defining the strategy to the completion of the product. When founded, the team consisted of four students of mechanical and two of industrial engineering. Today the team has 14 members and is supported by many experienced students and professors. Since this is the second participation in an FS event, the main goal for the Formula Student event in August is to score in all dynamic and static events. A place in the midfield would be a great result for the team and would help to establish the project for following years. Beside that the event is a great chance for the participating team members to get to know a lot of other motor sports enthusiastic students from all over the world.
