Info
UWB eRacing Team from the University of West Bohemia brings together students from four faculties who design, build, and race an electric Formula Student car. Founded in 2009, the team built its first fully electric vehicle in 2024. The latest car features a CFRP monocoque, 4WD powered by four motors, torque vectoring, and an adjustable brake bias. Through in-house engineering, the team transforms academic knowledge into real-world motorsport experience.
