Batteries power, 8 AAs, the motors and a Lithium powerbank to power the Micro:Bit - all included.  More information about the technical details and example software can be found on their site  https://www.cbis.education/robotic-car-kit#  including further details on the  L298N based motor controller/shield, which I found useful for programming it.   I have experimented briefly with programming it in Python (micropython), getting it to it move forward, backward; to the right and left, using the Mu editor.  The code is shown below for those who want to try i...
