Founded in 2001 at Chalmers University of Technology in Gothenburg, Sweden, by a team of dedicated students, Chalmers Formula Student has since upheld a legacy of innovation and excellence. We have now continued on that legacy, driving innovation through the introduction of our Electric system in 2015, and our Autonomous System in 2022 together with our loyal partners. Now, fueled by our past successes, we're more determined than ever to demonstrate our performance on the track.

At Chalmers we build a new car every year as well as a completely new team. This year we designed an easy-to-manufacture car for more extensive testing and has focused on validation of analysis by physical tests. Safety, adjustability and sophisticated software highlights the CFS16 car. We have self developed the BMS and processing nodes to better suit our car and keep the reliability high and weight low.
