Key Data

The xb023 is our third car with a combined electric and driverless platform. With the new regulations concerning the front impact structures, the typical TUfast high nose of the car that has appeared one every previos xb car, has been changed to one of the lowest ones we have ever had. Despite major changes to the deisgn, the 2023 contender managed to grab 2nd place overall at FSA as well claim a victory at driverless FSG Acceleration event.
