Williams move forward with blown rear end
Williams have introduced yet another major car update at Silverstone after introducing an effective F-duct at the previous Grand Prix, held at Valencia. The car already showed much improved pace in Spain, but at Silverstone both drivers could confirm their performances thanks to a new blown diffuser.
The change will obviously benefit the FW32 a lot as it previously featured high exhausts that appeared to disturb upper sidepod airflow quite a lot. The new sidepod slopes down much steeper, resembling much the design of the Red Bull. With this change, exhaust gases are now pushed onto the diffuser, allowing it to work more efficiently while drag will certainly have reduced above the sidepod.
I wonder if these teams worry about the variable exhaust flow through the diffuser. Doesn't that leave the driver with a car that has lower down force when the car is revving low? Maybe they just keep the engine at its limit around high speed corners.
