TecHNIcAl paOLO FiLiSetti Technical Editor TECHNICAL mOnaCO: SOme thingS neVer Change Monaco is a classic race on the calendar – the most classic. The ingredients of the technical recipe for Monaco never change through the years. In fact, notwithstanding the different rules that evolve in Formula 1 year by year, you can see that over the decades what is required in Monaco never changes when it is time to look at the packages and developments adopted. There are two key words which have a particular meaning along the street of Monaco; one is downforce, the second is handling. The first one is pretty obvious, as the average speed is the lowest in the calendar so all the teams try to generate as much as possible downforce to guarantee adequate grip to the cars, not taking into account the worsening of the drag figures, that have a really marginal negative effect here, with the exception of the tunnel section of the circuit. That said, it was interesting to note as a common feature, developed just for this race, was the ‘monkey seat’ placed over hot exhaust pipe. What was very interesting was the evolution introduced by Mercedes that sported a very complex assembly of this element. In detail, the monkey seat of the W06 Hybrid featured increased endplates extending from the tail end of the engine cover to the exit of the exhaust pipe. Furthermore, it was interesting to note that this element featured an array of four profiles. In reality those were grouped two by two so as to create a sort of ‘multiple’ diffuser directly on top of the exhaust pipes. This solution is said to provide an additional downforce load of 40kgs according to our sources – an important amount considering the twisty layout of the track. As mentioned, the other important element in Monte Carlo is the handling of the car, especially in the slowest corner of the track, at the Grand Hotel. An increased steering angle is required to cope with this kind of corner, hence some small changes are made to the front suspension wishbones to allow the wheels to have a more angled position. A small cut to the extremity close to the upright was visible on the Ferrari SF 15-T . This effectively improved the handling of this car in the slow corners, and at the same time didn’t change the relevant features of the front suspension. As we said, Monaco is a classical and unique track, where some simple and conventional tricks can help in guaranteeing competitiveness, even in the current super technological F1 hybrid environment. 31 GPWEEK.com // 31 GPWEEK.com // F1 >>> MONACO PARTNERS:
