Hamilton winner under investigation at Monza

Lewis Hamilton perhaps carried out an excellent operation this Sunday in Italy, scene of the last European round of the year. In addition to a new success in 2015, at the end of a Grand Prix outrageously dominated by the Mercedes W06 Hybrid n°44, the reigning World Champion took advantage of the retirement of his teammate Nico Rosberg to increase his lead at the top of the general classification.

However, the results still remain provisional since Lewis Hamilton and Nico Rosberg are under investigation for a possible violation of the tire pressure of the W06 Hybrid, which would be below the limits set at 19,5 PSI for the rear tires. Hamilton's left rear tire was reportedly measured 0,3 PSI below that value. This could explain the radio messages asking Lewis Hamilton to increase the pace at the end of the race to protect himself from a time penalty.

After a controlled start, which saw Kimi Räikkönen completely miss his start, falling to last position, Lewis Hamilton was never worried throughout the 53 laps. Behind the Briton, Sebastian Vettel hoist a Ferrari on the podium at Monza by finishing second, and also having benefited from Rosberg's retirement two laps from the end due to a probable engine failure, while the German driver was back on the heels of the quadruple world champion.

Felipe Massa completes the podium after having resisted the return of his teammate to Williams Valtteri Bottas. Kimi Räikkönen (Ferrari) made a good comeback after his failed takeoff, to fail in fifth position ahead of the two Force Indias of Sergio Pérez and Nico Hulkenberg. Daniel Ricciardo (Red Bull), Marcus Ericsson (Sauber) and Daniil Kvyat (Red Bull) complete the top 10.

Romain Grosjean and Pastor Maldonado (Lotus) had no success this Sunday, forced to retire in the first round. A contact for the Frenchman at the first chicane damaged the suspension of the Lotus n°8, while Maldonado damaged the bottom of his car also in this chicane. Fernando Alonso (McLaren) gave up in the final laps of the race.
