GP Week : Issue 122
Technical Update: European GP Is it a street circuit or isn’t it? Valencia is a strange combination, as GPWEEK Technical Editor Paolo Filisetti explains Despite being a street track, Valencia is a circuit, that only partially recalls Montecarlo. Although it lays around the harbor, it features a completely different layout in terms of combination of corners and straight. In reality there is not a proper straight line throughout the track, but at the same time, there are not plenty of slow corners as is the case in Monaco. Top speed therefore is not paramount there, but nevertheless you don’t need as much down-force as Monaco to negotiate the slower corners. Most of the teams didn’t bring many changes, waiting to introduce widely modified packages at Silverstone. As a result many teams adopted this race as a sort of testing bench for some solutions that will be introduced at the next race. This was the case for Ferrari who, on Friday, tested an evolution of their rear suspension. In particular this latest evolution sports higher pick up points so as to provide a lower roll centre as well a better camber recovery. The test provided some useful data to adjust the new solution in time for the next race. McLaren on the other hand introduced a new front wing based on the one introduced in Barcelona. The new one featured a revised single flap, characterized by a deep cut in the centre, so as to reduce drag on the straight but at the same time providing an adequate down-force, useful on the twisty section of this track, The endplates were also modified – in fact they sported a double air inlet whose function was to better direct the airflow close to the front wheels inner side. An interesting change was also introduced by the Red Bulls. They sported a different position for their front central barge boards, now are directly attached to the foremost section of the chassis, while the nosecone now doesn’t have any, compared to the previous version. In reality this should be a test carried out on Fridayonly, as an evaluation of the solution to be adopted for Silverstone, but the result was so good that both the cars kept the new set-up throughout the weekend.
