|Kubica encouraged by change of feeling in FW42|
The races leading up to the 2019 Chinese Grand Prix had seen ROKiT Williams Racing driver Robert Kubica suffer the frustrations of not only having a car that was not performing but also a car that compared to his team-mates car was producing quite different results in terms of the data coming from the car.
But after having completed the two Friday practice sessions Robert has finally been able to confirm that he is encouraged by a car that now has a "different" feeling.
The data that was coming from both the teams cars showed that there was a discrepancy between the cars showing an 8 per cent difference in aero balance front to rear under braking despite the two cars having the same settings. In braking this was seeing the aero balance on Robert's car moving further forwards than that which occurred on Russell’s. This would make Robert's car suffer from more oversteer from the initial turn-in and apex.
As for what could be the cause of this it could come down to a difference in torsional stiffness in the two chassis. The team has still yet to resolve this issue but it would see that they are making some progress as Robert's response was more favourable.
The two Friday sessions would
see Robert finish ahead of his team-mate but was even more encouraging was
the fact that the changes that had been made to the FW42 during the sessions
have produced the result of changing the handling.
