The choice of Mercedes will cost Hamilton 5 positions in Sunday’s Brazilian GP. But there were signs of structural wear on the W12’s heat engine. Team principal Wolff: “Then we will have three races with a new engine”
The official confirmation of the replacement of the internal combustion engine of Hamilton’s Mercedes power unit and the consequent penalty of five on the starting grid of the Brazilian F1 GP on Sunday highlights how reliability is crucial even more than the performance of the single-seaters in recent races. of the season. After the race in Mexico, the engine used by the English driver showed leakages, similar to those found on the engines replaced at Bottas in Russia and Austin. It would be the same structural problem that cannot be solved during the current season.
why the mercedes choice

The triggering cause seems to be in the choice to replace the English only the internal combustion engine (3 in the drawing), not the complete PU in Istanbul, to suffer a penalty of only ten positions. This element has made this element more vulnerable not having replaced the turbo (1) and the other ERS components, i.e. the MGU-H (2), the MGU-K (4), the electronic control unit (5), the battery (6). This choice, in Austin, but especially in Mexico due to the scarcity of the air, led to the adoption of extreme engine maps. In Texas the high frequency vibrations due to the disconnections of the asphalt, and in Mexico, an even more extreme map to compensate for the loss of power caused by the thinning of the air, have made the structural problem on Hamilton’s fourth engine clear.

To Sky’s microphones, Mercedes team principal Toto Wolff explained the decision: “This year we have an engine degradation problem, we usually have a loss of power in the engines but this year we notice that the loss is excessive. . We have decided to change now so as not to have difficulties in the last few races. Had we just changed it in Turkey? Yes, I know…”. The sentence died down on that embarrassed answer, and then resumed: “We know it will be a difficult situation, we have speed on the straight but we wait, here Red Bull can do first and second position, but then there will be three races – Qatar, Arabia. Saudi and Abu Dhabi – special, with two out of three circuits unknown for F1. So we’ll see … “.
