Formula 1 news on the technical front over the past few years has focussed a lot on suspension systems.

In particular, it has been the use of passive hydraulics to link the suspension to make the aerodynamics work better. Systems such as FRIC and after that was banned, hydraulic pitch control (HPC). This went further over the winter with Ferrari questioning the legality of an energy recovery self-pumping hydraulic system.

With the use of a few kids toys I explain what's been going on.
