Mercedes W05 – not just all about power TECHNICAL TeCHNICAL PAOLO FILISETTI Technical Editor The supremacy demonstrated in the first three races is a strong indication of the domination of the Three-pointed star outfit. The question is, what are the real strengths of the W05 . Already in the tests carried out on this track it was evident how easily the Mercedes drivers were able to run laps in succession and to make long runs . What surprised, was then their pace during the race simulations . This data was confirmed in all races run so far, and the analysis that we performed on the intermediate times, sector by sector, the maximum speed at the end of each sector, and the speed trap, analyzed in qualifying, this time allows us to get a detailed picture of the performance of this car. The first highlight is undoubtedly represented by the power unit – the data for maximum speed, also analyzed in relation to the aerodynamic configuration adopted , is quite significant when compared to the direct competitors. See, in fact, the comparison in Sectors 1, 2 and 3 and their relative speed. What strikes you is the ability to reach top speed very quickly, even in average slow sectors. An advantage of more than 15 km/h would suggest a difference of equivalent power of about 90hp , which is objectively impossible. The sector analysis, showing a particular efficiency of this car, helps us to find a more plausible reason, showing an advantage also in acceleration. In fact, we find a value for the ratio load/drag (Efficency) extremely constant, both in the medium and slow sections as well as the fast ones. This shows the absolute versatility of this car, not forced to increase the flap angle of the wings, in favor of handling in the twisty sectors. If we compare the efficiency Mercedes to that of the Red Bull, we note that the maximum value of the ratio load/drag, for the RB10, is definitely high – essentially in a straight line and in the fast corners. The RB10 shows itself, compared to the W05, to be a car that fits the top speed sectors, and not the slow ones. The need to increase the wing loading (in these sectors), both in Melbourne and in Malaysia, supports us in our deduction. As well, the Mercedes engine is delivering strong power, although not 100%, thanks to the integration between the internal combustion engine and the MGUs being better than the others. It could be said to be 90-92 % of the maximum performance possible, against 85-87 % of rivals, including Ferrari. It also has extremely SAKHIR QUALIFYING SECTOR ANALYSIS T1 TIME ANALYSIS 29.5 29.7 29.9 30.1 30.3 ALONSO RAIKKONEN VETTEL RICCIARDO MAGNUSSEN BUTTON MASSA BOTTAS HAMILTON ROSBERG T1 T1 QUALIFYING SECTOR ANALYSIS T1 SPEED ANALYSIS 235 236.8 238.6 240.4 242.2 244 245.8 ALONSO RAIKKONEN VETTEL RICCIARDO MAGNUSSEN BUTTON MASSA BOTTAS HAMILTON ROSBERG SPEED 1 SPEED 1 36 GPWEEK.com // 36 GPWEEK.com // F1 >>> BAHRAIN PARTNERS:
