Team wob-racing has been founded in 2003 and is taking part in Formula Student events since 2005. We are going to built our 19th car this year. Let's get driven by e-motion!
This Year's Car
2026
Info
Founded in 2003 at Ostfalia University of Applied Sciences, Team wob-racing is one of Germany’s Formula Student pioneers. After years of developing combustion and later electric race cars, we proudly present our 20th vehicle, the WR20 “Jolie”, featuring our first fully integrated driverless system. With more than two decades of racing heritage, wob-racing has become Wolfsburg’s second largest automotive manufacturer, driven by passion and emotion.
Engineering Design Priorities:
Driverless Integration

Team wob-racing’s making history in 2023, that’s for sure. Founded in 2003 by Automotive Engineering students, we’re celebrating our 20th anniversary. Now we’re proudly bringing our WR17 on track. More than 45 % increase of downforce @60 kph, in-house developed inverters and a slimmer monocoque are just few examples of our result of hard work. After a year without events, we want to make a good start and reward all the many students who've given a lot in 20 years of Team wob-racing.

The Team wob-racing from the UAS Ostfalia was founded in 2003. After 7 combustion cars the team focused on the construction of electric vehicles. This means that the Team wob-racing has been Wolfsburg's second largest automotive manufacturer for 16 years. With 35 team members our innovations from the past season were completely modified and expanded including a live telemetry and a full Aerodynamic package. A weight reduction of 10 kg was achieved despite all the innovations.

Wob-racing is the Formula Student Team of the University of Applied Sciences Ostfalia in Wolfsburg. Founded in 2003, this year we celebrate our 10-Year anniversary. At the same time we present our tenth car, the WR09-E. This electrically driven car is our 3rd with this drive concept, having built seven combustion cars before that. Right now our team consists of about 35 members, who designed, built and tested our newest prototype. The team is divided into a technical and a business part, both sections headed by a project leader. To support those two, the construction and production coordinator helps two keep the deadlines at the back of our minds and supports our team members. The WR09-E has a self-developed electronic system (e.g. telemetry, measuring unit), uses adapted industry components and has an advanced chassis. After two years of using the distinctive skin design wob-racing developed in 2010, we decided to take on to something new altogether this year. See you in Hockenheim!

Info
This year team wob-racing decided to step into the development of future technologies and take part in the Formula Student Electric. With that decision wob-racing looks for a new challenge after building combustion racecars for seven years. During that time we could collect a lot of important experiences with combustion engines. That is why we decided not to switch the type of drive completely but to build two independent cars. With a clever developing strategy this decision brings us the possibility to create a lot of synergy effects which save time and money. That is why we formed a common platform that is the basis for both cars. We also set ourselves again several main targets. Our whole development is affected by these simple main goals. These targets are: 1.) Reliability 2.) Safety 3.) Performance 4.) Quality. This new task meant to be the biggest step since the team foundation in 2003 and it challenged us in many ways. The more proud we are to present the result: The WR07-E!
