xb021
Key Data
Our first vehicle with a combined electric and driverless platform is the xb021. It is one of the few cars built during the corona pandemic in just one year. The team opted to continue building a new car in order to keep the knowledge transfer afloat. Due to our desire to modify the electric vehicle with the autonomous system, this was more crucial than before. As a result, the xb021 was built.
