Team Profile
At Karlstad University, the Formula Student team Clear River Racing (CRR) is a stand-alone course that students participate in outside the curriculum. So far CRR has only built petrol vehicles, but since EVs are the future and we want to keep up with the times we also compete in Class 2 with an EV. And since this is our “EV-debut”, the keyword is “simplicity”. Therefore we only use one engine, a YASA 750, which is mounted on the driveshaft. The battery box is our own design and it contains 392 5Ah battery cells which are cooled by air.
