3.6 seconds slower than the fastest car, the BMW. Bearing in mind that they were running grooved tyres, the lap times should be very similar to last season.

Williams is not using a purely mechanical version of KERS, just a mechanical method of storing energy. (I think!)
[From autopsort.com's weekly journal]Q: Finally, talking packaging of KERS. Because of the different aero the car will look different, but the cars could also look different because of KERS as you've got to package capacitors or batteries or whatever you choose to specify. How much has that affected the packaging of the car and therefore how much does that effect the aero of the car?
Vasselon: From a visual point of view the KERS will not be visible. So in most cases it will be very difficult to detect a car which runs KERS from one which doesn't. Yes, it's big, I think 30, 35 kilo, but not big to the point that you can say 'here's where the KERS is mounted'. We have already been discussing this in the last Technical Working Group (TWG), not all the teams, but several, are planning to put KERS below the fuel cell, so this kind of integration will make KERS almost invisible.
Q: That's if they're running a battery.
Vasselon: No, why?
Q: Well if you're running a mechanical system, then you can't put it under the fuel cell, the flywheel...'
Vasselon: You have different types of flywheels. Starting from the same energy storage concept the flywheel, you can either drive it mechanically via the gearbox and you have to be reasonably close to the 'box, of course. But you also have electrical flywheels, the flywheel is just a motor generator. In this case you can put it where you want, you just need wires.
pgj wrote:@WhiteBlue, you may be right. I just put out my understanding of the flywheel to test my understanding as much as anything. I have no reason to doubt your reasoning or that of Scotracer.
That is a useful diagram Scotracer, where did it come from?
