Veteran technical journalist Giorgio Piola is writing that Lotus Renault GP has a system which brings back echoes of the “mass-damper”, one of the innovations when the team was known as Renault, that helped to win it the 2006/6 world championships.
According to Piola, the system is mechanical, operated by the driver (like the F Duct) and means that when the driver hits the brakes, it manages the ride height as the front of the car dives down, which in turn helps to keep the front wing’s performance more consistent.
The system enables the team to run a lower front ride height, as the thing which dictates how low the ride height can be on an F1 car is the limit of downward movement at the moment of peak braking.
