When was Mercedes informed by the FIA?

D he Technical Delegate of the FIA, Jo Bauer, checked the tire pressures on the cars of Kimi Raikkonen, Sebastian Vettel, Nico Rosberg and Lewis Hamilton less than five minutes before the start of the race. In each case back left. While the air pressure in both Ferraris was over 19.5 PSI, the Mercedes fell short of the mandatory requirements. Rosberg even by a whole 1.1 PSI, which was no longer important due to his engine burst.

For Lewis Hamilton, on the other hand, the air pressure that was 0.3 PSI too low at the start played a major role. The World Cup leader had to tremble about his third Monza victory until 5:48 p.m. That was a good two and a half hours after the end of the race.

But when did the FIA ​​inform Mercedes about the starting pressures that were too low and the subsequent investigation? 'It was about ten laps before the end of the race,' said team principal Toto Wolff. Mercedes then asked its driver to increase the speed in order to increase the lead over Sebastian Vettel. 'We thought that a possible penalty could be 25 or 30 seconds,' said Wolff. On the finish line, Hamilton took a total of 25.042 seconds from the Ferrari.

How could Mercedes avoid a penalty?

When the Mercedes engineers checked the tire pressures on Hamilton's car, everything was OK. At the time of measurement, the black rubbers were in the tire warmers, which in turn were connected to a generator. The FIA ​​didn't check the pressures until later when the mechanics buckled the tires on the car with the starting number 44.

At this point in time, they were still wrapped in the electric blankets. But these were no longer connected to the generator. As a result, there was a lack of electricity to generate heat. This caused the tire temperature to drop. And consequently the pressure.

In the end, Mercedes saved a faulty communication between FIA and Pirelli. 'We stuck to the previously defined procedure. A Pirelli technician was there when we measured the pressure for the last time,' explained Toto Wolff. 'If the FIA ​​wants to measure the exact pressure before the start, they should actually do it before the traffic lights go out. But that's bad.' The commissioners agreed with Mercedes. It certainly helped that the tire pressures in the race were consistently above the prescribed levelThe minimum values ​​were.

Why didn't Raikkonen move?

For the first time since the 2013 Chinese GP, Kimi Raikkonen placed in the front row. But instead of taking advantage of his good position, the Iceman totally botched the start and was handed back to the end of the field. 'The second clutch pedal was not in the right place,' reported the 35-year-old, giving the technology the buck.

'The engine then went into anti-stall mode. Until I did it took a few seconds to set everything back up. ' Explanation: The second clutch is used by the driver to control the torque. The anti-stall system prevented the engine from stalling.

Maurizio Arrivabene could not quite follow the explanations of his driver. The Ferrari team boss suspected a human error behind the messed up start. 'On the TV pictures it looked like Kimi had problems with his fingers. But I haven't looked at the data yet.'

Why did Bottas catch up on Massa in the end?

Felipe Massa was the faster man in the Williams camp in Monza. In qualifying the little Brazilian Valtteri Bottas qualified, in the race he controlled his Finnish team-mate until shortly before the end. Then Bottas suddenly appeared in Massa's rearview mirror and attacked. The veteran defended himself successfully and defended his podium position.

The reason for the final duel was in the first pit stop. Because Williams and Massa tried to keep Nico Rosberg behind them, Massa was ordered into the pits one lap after the Mercedes driver on lap 19. There the mechanics switched from soft to medium.

Bottas, on the other hand, stayed out three laps longer. Which was an advantage in the back. 'The rear tires died. The last three laps were very difficult. Valtteri had the better traction. Fortunately, I was able to keep him behind me.'

How did the Lotus turn out?

For Lotus, the Italian GP was over after one lap. Then Pastor Maldonado's car stood in the pits with a crooked front suspension, and Romain Grosjean parked his E23 on the side of the road with the rear suspension cracked. It was difficult to filter out the actual course of the Lotus execution from the statements of those involved.

If the team's press release is to be believed, the drivers were innocent victims of two separate collisions. But the alleged perpetrators denied any responsibility. So what happened Grosjean was in a clean sandwich when approaching the first corner. Inside Marcus Ericsson, outside the sensationally started Felipe Nasr.

Ericsson touched the Lotus from Grosjean very lightly. He takes a short sideways position, corrects and hits Nasrs Sauber with the front wing on the right rear tire. Starting theThe Brazilian immediately senses chicane that he has a flat tire. At Grosjean, the rear suspension is gone after touching the two cleansers. Regardless of this, Maldanado wants to avoid the tumult of the fighting in the braking zone and flees into the emergency exit. When he fired back on the track, he almost cleared Nico Rosberg. To do this, he meets Nico Hulkenberg's Force India. At the front right of the Lotus, a wishbone breaks at the attachment point to the wheel carrier. Hülkenberg later noted an inexplicable loss of downforce in the rear. Possibly a consequence of the collision.
