Technical insight: Renault's J-damper
There has been a lot of chat about Renault's 'J-damper'. But what is it exactly? Craig Scarborough explains
This year's technical innovation has taken a while to appear. But from first mentions in the Renault spy case to teams discussing the technology more openly in the first races, it seems there has been a return to Mass Dampers. At first this appears to be a new development, but the J-Damper actually predates the Mass Damper. And, bizarrely, isn't even a damper at all.
Unlike the Mass Dampers of 2006, these solutions are smaller and more integrated into the car's suspension. Initially co-developed by McLaren and Malcolm Smith, a Cambridge engineering don, these are technically known as 'Inerters'.
