Robert Kubica cautious before Interlagos

Robert Kubica (Renault), after several disappointing races, left Korea with a fifth place. Despite this good result, the Pole knows full well that he must remain cautious. The Interlagos circuit being very different from the others, Kubica remains in doubt as to the R30's ability to adapt to it. “ He's a bit unusual and it's really difficult to know what our level of performance will be. On the long straight at the end of the last corner, the f-duct will give us a lot of gains; This is also where engine power will play an important role. I think it will be a bit of a lottery with the weather being unstable in Brazil at this time of year. When it rains, the grip on the track is very weak and you have to be lucky if you find the right balance for the car. »

In addition, the Pole explains that Renault will have to compromise on its car in order to make it as efficient as possible. “ It is difficult to tune the car on this circuit, which combines a long straight and uphill sections. You have to choose between top speed and aerodynamic downforce, which saves time in turns? it is difficult to find the right compromise. The circuit has a bit of everything: high and medium speed, and it?s in a way a more traditional layout. It is possible to save time in quite a few places. But, as I said before, it is quite difficult to find the right compromise with the balance and tuning of the car »

If the Renault R30 can be fast on this track, then the Pole will have the opportunity to stand out. “ Interlagos is a circuit which presents good overtaking opportunities, the best being at the first corner. If you are in the right slipstream on the straight, you can brake late and move on to diving on the inside. Last year, some cars had a dry track tune-up and others for a wet track. We could see a big difference in speed between some of them. »
