According to Sam Michael Williams have problems with the software driving the inverter. That is bad news in my view. Williams have decided to buy all the KERS components from the source and that means the operating software for their IGPTs will be unproven. It could take them some races to fix all the problems they have. Williams shares went down below €23 today.roadie wrote:So, more KERS issues keeping the car in the garage.

Does anyone think in the photo above they have opened up the rear of the car for cooling?
