Team Description
DHBW Engineering Stuttgart - a team of nearly 130 students of the Cooperative State University of Baden Wuerttemberg. Founded in 2008, we have been participating in the Formula Student Combustion until we decided to switch to Formula Student Electric in 2011. What distinguishes us from most of the other teams is that all of our team members spend one half of their days at university and the other half in their training companies. Because of this and all other challenges that arise from Formula Student is why we depend on a perfectly harmonizing team to build our A-Team-E-Car.

The eSleek15 was designed under a few general decisions. At first was designed to be reliable and well-balenced in order to compete well in all disciplines at FSE. Furthermore the target weight was reduced to 171kg. Focusing an mechanical innovations the elctric systems should only undergo minor changes. All in all the main focus of the design process was the improvement of the vehicles dynamics. Therefore a completely new kinematic was combined with improved software and an aerodynamic package.

Info
Our latest car eSleek14 is designed under following general decision. At first we want a reliable car, well-balanced for all events on FSE. Then we want to reduce the weight down to 180Kg. The electrical system should not changed in general compared to eSleek13 to concentrate on mechanical innovation. And at last the center of gravity should be lower, to optimize the dynamics of the car.This is achieved with a CFRP full monocoque and 10" wheels as the most obvious changes.

Info
200 kg - 600V – 1000 Nm these figures should give you an idea of the eSleek13, the fifth and latest development of DHBW Engineering Stuttgart. Throughout the design process our main goals were to create a high performance, lightweight concept to perfectly match the demands of the formula student competition. Equipped with two highly efficient motors our interpretation of a formula style racecar has a total system power of 66 kW (90 hp) resulting in an impressive power to weight ratio of 2.2 kg/hp. The Chassis, which now consists of a hybrid structure made of a carbon fiber monocoque and a tubular steel frame is undoubtedly the most significant innovation to this season’s eSleek. This gave us the opportunity to develop great know how in the field of carbon fiber reinforced plastic and offers great potential for eSleek14. We would like to thank FSG and our sponsors for making it possible to participate in this great event and wish all teams the best of luck for the competition!

Info
The DHBW Engineering Formula Student Team from the Cooperate State University Baden-Württemberg was founded in 2008 and already passed three successful seasons with a combustion car. The overall victory in Barcelona was a dignified ending of the combustion era and the development of the first electric car started in September 2011. Thanks to our sponsors we are now proud to present our eSleek12. The totally new electric drivetrain consists out of 2 synchronous machines with a 2-stage gearbox, very lightweight power electronics and a modular battery consisting of 400 single cells. Our tubular space frame and suspension were further optimized and a significant weight reduction of more than 10 kg could be reached. We are looking forward to an interesting season and wish all teams good luck.
