Four-wheel-drive donuts are the most balletic donuts. Case in point: this dizzying, totally rad donut machine built by the TU Delft Formula Student team.
TU Delft puts it best in their description for the YouTube video.
The advantages of four-wheel-drive:
— Slip Ratio Control
— Torque Vectoring
— DONUT BUTTON!
