German Grand Prix: Friday press conference - Pt.2

I think it goes back to the intro question that David asked. All the work we do on this year's car and any investigative work, whether it gets good correlation or not, is still valid for the 2014 car because you're trying different things to understand... you can clearly measure where you have deficiencies and when you try and do changes for the track, whether you measure them here during Friday testing that we do or any future Grand Prix Fridays. When you get those components and then you feed that information back to the design office and wind tunnel, that loop that you close generates information, whether the test was positive or negative, so that's how it will feed into next year.

Q: (Dan Knutson – Auto Action and National Speedsport News).
Pat and maybe Paul, the minimum tyre pressures have gone up, I believe, when leaving the pits by only one pound. How can one pound make that much difference? When we look at a road car it doesn't make much difference at all.

Pat Fry:
In terms of car balance, we obviously do play around with pressures, change of balance from qualifying to the race. It's a standard tool that everyone uses. And also the higher pressures... you can worsen your long run by increasing your rear pressures. It's a tool; as long as everyone is working to the same limits it's fine. There is a tendency, if you've got an oversteering car, to try and run the pressures as low as you can at the rear or higher at the front. That's just a normal way you chase a car balance.

Q: (Dan Knutson – Auto Action and National Speedsport News).
From a safety point of view, why is it much better to have...?

Pat Fry:
Well, I think maybe that's a question for Paul.

Paul Hembery:
Well, you've got to have a starting point and it's what happens as well as the pressures grow which is also important. Another thing we were conscious of as well after Silverstone is the safety car period which was extended. Normally that's not a great issue because you don't drop too low but when you're at a circuit like Silverstone, if you restart and you've dropped down below almost the starting pressures, then that can create other issues, so that's something else that we're studying at the moment. Road cars, well I don't think people check their pressures too much on road cars, sadly, which is why the European Union I believe have introduced new digital measurements on new cars going forward for pressures. It's still very important; whichever car you're driving, you need to check your pressures.

Q: (Dieter Rencken – The Citizen).
Primarily for Pat and Paddy; the 2012 spec tyres have got a different shape to the 2013 tyres. That shape is being introduced from Hungary. What aerodynamic effect do you believe this will have on your cars?

Pat Fry:
Obviously the shape of the tyre is critical to the aerodynamics around the front wing and around the diffuser. We just need to re-optimise in those two areas. Obviously we have the wind tunnel tyres for both so we need to get in and start comparing and seeing what adjustments are needed. It's impossible to say if it's going to benefit one car more than another. I don't know. I guess we'll find out in Hungary.

Paddy Lowe:
Yeah, there are differences but we're aware of those differences because it's a tyre, obviously, that we used and developed around last year, so we can look at that when that's been finally confirmed and optimise the car around that.

Q:
Could it be a benefit to either McLaren or Sauber?

Sam Michael:
I don't think so but I don't know to be honest. I don't think anyone really knows. Probably the best comparison is that we've all done that test in Brazil, Friday, last year when we compared 2012 casing to 2013 and the changes were not significant so that's the only piece of data we've got. As Pat said, we've also got all the wind tunnel tyres and things like that. The main thing is that the changes are being done for safety so it's second order what effect it has on the performance.

Tom McCullough:
Nothing really much more to add. As Sam was saying, safety's really the most important thing, whether it increases or reduces the performance of our car we shall see once we get out on the track.

Q: (Ian Parkes – Press Association).
Paul, there are no guarantees in anything but what degree of certainty can you say that the tyres you have here and the tyres that you will have from Hungary onwards are safe?

Paul Hembery:
