TECHNICAL mIxeD messages ON FerrarI’s tOKeN sPeND teCHNICAL PaOlO FIlIsettI Technical Editor the race in Montreal was highly anticipated for its technical contents relevance. It was in fact the race where Ferrari decided to bring in the developed version of its power unit, using three tokens of the 10 that the Italian team had saved from before the start of the season. It was interesting to see whether this evolution would bring a substantial gain, capable of dramatically reducing the gap to the Mercedes cars. The Italian squad also introduced a slightly revised version of the front wing, notably in the upper winglets area, now featuring a longer vertical fin curved outward close to the inner shield. This was a small change, finalised to adapt the aero package to a low-downforce configuration, useful on this track. The car seemed to respond positively to all the changes introduced, but it was virtually impossible to precisely analyse due to the problem encountered by Vettel in qualifying and Raikkonen’s mistake in the race. It seemed that the revised SF-15T had gained pace compared to the Mercedes, but to have a proper verification we will have to wait until the next race, in Austria, where the circuit layout will certainly be able to show all the points of strength and even weaknesses of the Italian car. Mercedes on the other hand looked pretty conservative in their approach to this race. While it was expected that the Brackley-based team would spend few token in their power unit development, they instead decided to postpone the introduction of the evolution version to a later stage of the season. The car in Canada just showed some aero refinements – in particular a revised engine cover, sporting a bulge in the bottom section that hid a bigger radiator for the ERS that has been especially introduced for this race and for the next one in Austria. Furthermore it was interesting to note the retention of the full aero package adopted in China, with just some minor differences. The long straight before the start-finish line in a way mimics the long back straight of Shanghai. The rear wing thus featured the flap with the side cuts close to the endplates, so to reduce the drag and increasing top speed. The two leading teams, even if Mercedes is currently extending the gap on Ferrari, keep a close eye on each other. Notwithstanding the positive result in this race, Mercedes seems unsure that Ferrari was able to show its real pace gain due to a partially troubled weekend. Sources told us that in Austria it should be possible to see a closer battle and that, last but not least, Mercedes could be forced to finally adopt development countermeasures in order to keep their current gap over their direct opponent. The same source told us that this European summer could be ‘hotter’ than expected in the championship battle. We will see... We usually trust this well- informed source so we will keep our eyes and ears wide open in two weeks' time... 31 GPWEEK.com // 31 GPWEEK.com // F1 >>> CANADA PARTNERS:
