Suspension design on the 2cv was a very specific consequence of the "egg" design brief:

> This suspension design ensured the road wheels followed ground contours underneath them closely, while insulating the vehicle from shocks, enabling the 2CV to be driven over a ploughed field without breaking any eggs, as its design brief required.
