2017 Malaysian Grand Prix

The 2017 Malaysian Grand Prix (formally known as the 2017 Formula 1 Petronas Malaysia Grand Prix) was a Formula One motor race that was held on 1 October 2017 at the Sepang International Circuit in Selangor, Malaysia. The race marked the 37th running of the Malaysian Grand Prix, and the 19th time that the race had been run as a World Championship event since the championship's inception in, all World Championship events having been held at the Sepang International Circuit. This was also the last Malaysian Grand Prix, as the race had not been contracted for the season and beyond.

Mercedes driver Lewis Hamilton entered the round with a 28-point lead over Ferrari's Sebastian Vettel in the World Drivers' Championship. Hamilton's teammate Valtteri Bottas was third, a further 23 points behind. In the World Constructors' Championship, Mercedes held a lead of 102 points over Ferrari, with Red Bull Racing a further 143 points behind in third place.

Driver changes
Reigning GP2 Series champion Pierre Gasly made his Formula One debut, replacing Daniil Kvyat at Toro Rosso. The first free practice session saw several substitute drivers take part, including Sergey Sirotkin filling in for Nico Hülkenberg at Renault, Charles Leclerc replacing Marcus Ericsson at Sauber, Antonio Giovinazzi replacing Kevin Magnussen at Haas, and Sean Gelael taking the place of Carlos Sainz, Jr. at Toro Rosso.

Free practice
The second free practice was red-flagged after Grosjean crashed heavily at Turn 14. Valtteri Bottas and Kimi Räikkönen dislodged a drain cover embedded in the apex of Turn 13. Grosjean, the next driver through, struck the cover which sliced into his rear wheel. This caused the rear tyre to immediately deflate as Grosjean put load onto the steering wheel, causing him to spin into the barrier on the outside of Turn 14. The third practice session was concluded with Kimi Räikkönen fastest but his teammate Sebastian Vettel had an engine problem that required a replacement.

Qualifying
Sebastian Vettel failed to set a time in Q1 as his replacement engine did not run properly meaning that he would start last on the grid. Championship leader Lewis Hamilton took pole position with a time of 1:30.076, ahead of Kimi Räikkönen and Max Verstappen.

Race
Kimi Räikkönen pulled off the grid due to a power unit issue. Hamilton got off well with Ricciardo, Bottas and Verstappen behind. Verstappen overtook Hamilton for the lead on lap 4, and led until lap 28 when he pitted, leaving Ricciardo in the lead. Ricciardo then also pitted and Verstappen retook the lead. Coming into the last laps, Hamilton tried fighting back but Verstappen won comfortably to take his second win in his career, a year after his previous at the 2016 Spanish Grand Prix.

Meanwhile, Vettel came back from last to 4th through the field, almost overtaking Ricciardo in third. After the race Lance Stroll and Vettel collided on the cooldown lap, wrapping Vettel's left-rear tyre over the right side of the car. Pascal Wehrlein gave him a ride back to the paddock after the crash.
