QUESTIONS FROM THE FLOOR
Q: (Mike Doodson - Grand Prix Week) I’ve been very puzzled by the clutch stories we’ve been told. We haven’t been given a lot of information about what the procedure was and I wondered, now that it’s no longer what it was, whether one of you could explain to an ignorant journalist exactly how these clutch procedures worked. I understand there are two clutches, you give advice to the driver over the radio, you’re not allowed to do that anymore. Could I ask for a volunteer from the front row to go through the procedure just for me?
JA: The overall procedure is fairly long and tedious so I will try and shortcut it a bit. When you go with the car from stop to going, there’s a certain amount of grip available on the track. The tyre has a certain amount of grip, the track has a certain amount of grip, you want to go as close to that available grip as possible but not over it and you don’t want to go under it otherwise you’re not making as much performance as there is available. Now if you were super duper skilful you might have fingers that could judge exactly where that grip is but it all happens very, very fast so a perfect start is one where you can just let go of the clutch, let go of it and it closes to the perfect point where it delivers exactly the right amount of torque, such that the tyre doesn’t light up and spin, but neither does it give less torque to the road than the road is capable of taking. So our job, during the weekend, is to try to judge exactly how much grip is available and to adjust our clutches so that when the driver says go, the clutch closes the perfect amount to deliver the perfect amount of torque to the road and then off it goes. And that’s something that happens without the driver adjusting stuff, he doesn’t fiddle around with his fingers. The way that we used to do that in the past was there’s two clutch paddles, one which he holds all the way in, keeping the clutch fully open and the other which he holds in a partially closed and open position. We then, as engineers, adjust the clutch so that this partially closed and open position is at exactly the right point to get this magic start. And then when the light goes green, he lets go of the first clutch and the clutch closes to the point that is being held by the second paddle. Off the car goes.
All that’s changed is that now we‘re not allowed to advise or make any adjustments to that biting point between when the car’s on the grid preparing for the start of the race and when the driver actually does it so the parade lap start and the real start is done all by the driver and if he thinks it’s not closed enough or too open, he has to make his own judgement about that and make the calls. We can be sitting in the garage going ‘no, don’t do that’ but we don’t have any power to stop him.
