The E22’s relative performance looked to have improved in Singapore, what can we attribute this to?
There are a couple of things that helped us look more competitive. Singapore isn’t a ‘power’ track, so that helped us. We also took aero improvements and it contributed in making the car easier to drive and both Pastor and Romain felt the E22 was more consistent. I think we have a good chance for more points this season. The car has improved since Hockenheim when we took our front-rear interlinked suspension off and lost a chunk of performance. We have gradually fought back since then so we are in a position where we think points can be scored, if the races go the right way.
Both Pastor and Romain had turbo wastegate issues in qualifying, what light can be shed on this and what can prevent a reoccurrence?
We changed the wastegate and engine hydraulic manifold for the race and we didn’t have a problem. This is something that us and Renault Sport F1 are investigating thoroughly to ensure there is no repeat of the same scenario. There is already a clear diagnosis for Romain’s problem and appropriate measures have been taken. Pastor’s issue was actually different and all parts related to that issue have been thoroughly tested for Japan.
Suzuka is a very distinct circuit – what are the challenges?
The challenges are the high speed corners. You can’t run maximum downforce in Suzuka - as you will end up a little too slow on the straights - so you need to give the driver sufficient downforce to give confidence in the fast twisty bits whilst not clipping their wings down the straights. This is part of the reason why Suzuka is such a driver favourite, as drivers can be absolutely on the limit without the car totally stuck to the ground through maximum downforce. It’s not just having sufficient downforce, it’s ensuring that this is delivered in a balanced nature. Getting the suspension set-up spot on is essential here too. You need to extract all the grip that’s possible from the car. Looking at the E22, we think that it should be reasonably matched to all of these challenges especially as we’re generally quite good in high speed turns.
Looking at the remaining five Grands Prix, where could be a challenge and where could we fare better?
Japan gives us nothing to fear and we should be competitive. Russia is probably the same but it’s hard to tell when it’s a new track on the calendar. I think all of the remaining circuits offer opportunities for us being more competitive. Brazil is possibly a little bit more challenging because of the power hungry nature of the uphill exit from the last corner, and the long straight combined with the altitude, although we won’t be too bad in the twisty sections.
