Lewis Hamilton extended his lead at the summit of the Formula One World Drivers' Championship as he won the 2015 Italian Grand Prix on Sunday having led from start to finish and overcoming a problem with his car at the close.
It seems Hamilton may have been dealing with low air pressure in his tyres, and the Englishman faced a stewards enquiry into the matter, as the Daily Mirror's Byron Young shared:
However, Formula One's Twitter account revealed that the "stewards [decided] to take no further action." Hamilton weighed in following the race:
Sebastian Vettel was a distant second, while a late engine failure for Nico Rosberg meant he was unable to take advantage of Kimi Raikkonen's stall on the starting line and robbed him of a podium finish.
Felipe Massa rounded out the top three.
Here are the results from Sunday's dramatic action and the points standings:
The race began in dramatic fashion as Raikkonen stalled. From the pole, Hamilton hit the opening chicane first with Vettel close behind, while Massa, Valtteri Bottas and Sergio Perez all overtook Rosberg, who was stranded behind the Finnish star.
Lotus weren't pleased with their start to the race, which saw both Romain Grosjean and Pastor Maldonado retire in just the second lap after both cut the first chicane in the start-line scramble:
Rosberg made some headway into clawing back up the standings as he passed Perez, but Hamilton was taking full advantage of his comfortable start to establish a four-second lead over Vettel as he powered ahead with nothing but track ahead of him.
Rosberg continued to hound Bottas at every opportunity, but the Mercedes driver was forced to ease up after being repeatedly warned by his team that his brakes were overheating, per Sky Sports F1:
The German pitted on the 19th lap and successfully undercut Massa when the Williams driver made a slightly slower stop shortly after.
His team-mate Bottas soon followed, which allowed Rosberg and Massa to overtake him, and the Finn found himself back in seventh.
Raikkonen was bumped up to third amid the multitude of pits, but he was soon overtaken by Rosberg in Lap 28. Hamilton and Vettel, meanwhile, pitted together, emerging supremely comfortably ahead of the field.
Determined to hunt down his compatriot on fresh tyres, Rosberg picked up the pace only for Hamilton to do the same out in front. The Englishman set a new fastest lap of one minute, 27.544 seconds before doing so again just three laps later.
As Formula One demonstrated, the world champion had built up a significant lead over his competitors:
Indeed, Hamilton was so comfortable that he discussed with his team ways to preserve the engine over the final 13 laps.
Behind him a fierce battle for second place.
Rosberg continued to push Vettel as hard as he could, but the Ferrari man proved equal to every attempt. In the 43rd lap, the pair both recorded the exact same time—1:27.394.
The 30-year-old's attempts to secure the runner-up spot eventually ended in an unfortunate retirement just two laps from the finish as his engine gave out:
Hamilton also had some hints of car trouble as he was instructed to keep up his pace at the climax of the Grand Prix, but he nevertheless crossed the finish line quite some time ahead of Vettel.
Mercedes boss Toto Wolff would not reveal the issue Hamilton suffered in his final laps:
However, it seemed likely to be linked with the investigation into his low air pressure.
The win is Hamilton's seventh of the season, and the Englishman moves to 252 points in the F1 world championship standings—53 ahead of his Silver Arrows team-mate.
Expect the Englishman to make more significant headway to winning the world title at Singapore on September 20.
