With its fourth electric race car, the Bodensee Racing Team isonce again aiming to set new technical standards for the Iltisseries of race cars this season. For the first time, a race carof the HTWG Konstanz with a carbon monocoque will start at the FSG. A completely new Driverless System featuring a combination of lidar and camera will see the us compete for points in the Driverless Cup. We are looking forward to racing at theHockenheimring for the 13th consecutive season. See you ontrack!

With its third electric race car, the Bodensee Racing Team is once again aiming to set new technical standards for the Iltis series of race cars this season. It will be the first time a race car from the HTWG Konstanz with 4WD and wheel hub motors is taking part in the FSG. Furthermore, featuring a new evolution of our accumulator and a new 10" suspension with additive manufactured uprights. We are looking forward to racing at the Hochenheimring for the 12th consecutive season. See you on track!

This year we present our second electric vehicle which is the 16th car in our team history. Learning from the first steps our electrical Iltis took at last year's FSG, we are proud to release our new and improved Iltis22E. Working towards a big technical breakthrough next year new manufacturing methods were used (e.g. 3D-printing of metal/endless carbon fiber reinforced onyx polymer) in order to save weight and improve the familiar 2WD concept further to maximize the potential it has to offer.

This year we are proud to present to you our team's first ever electric Formula Student car: the Iltis2021E. It is the result of almost three years of work, since the design of the accumulator and drivetrain already started parallel to the 2019 season. The car has a 600V accumulator, which supplies a Lenze DCU inverter. The inverter drives the two Emrax 208 electric motors mounted in the rear of the vehicle.
