The 2025 Singaopore Grand Prix was a title-winning affair, although one with a highly controversial moment to go with it.
The Marina Bay Street Circuit delivered a surprising grand prix, which saw McLaren continue to face tough opposition after its early season dominance.
It was a weekend which showed that the remaining six races could offer a variety of race winners, with the top four teams having a different approach to further upgrades this year.
There was some impressive performances, but also some who will be wanting to quickly forget the weekend in the Southeast-Asian nation.
So, who has made the RacingNews365 list of winners and losers for the 2025 F1 Singapore Grand Prix?
Viewed by others:
Winner - McLaren
After scoring more than the required 13 points, McLaren sealed back-to-back constructors' titles, something it has not achieved in 34 years.
While it was not a McLaren on the top step of the podium in Singapore, Lando Norris finishing in third and Oscar Piastri in fourth comfortably secured the championship.
It is nothing more than the Woking-based outfit deserve after what has been a dominant campaign, which has seen 12 of the 18 completed races won by a driver in papaya.
McLaren do require 211 points from the final six rounds to beat Red Bull's 2023 record for the most points scored in a season, although its greater focus will now be on ensuring that either Piastri or Norris seal a maiden drivers' title.
With the constructors' title won, McLaren was undoubtedly a winner in Singapore; however, it was also a loser...
Loser - McLaren
McLaren might have won the constructors' title in Singapore, but at what cost? Norris colliding with Piastri on the opening lap has created an intra-team problem, with the controversy having overshadowed the outfit's celebrations.
Norris dived up the inside of Piastri at the third corner on the opening lap but made contact with both Max Verstappen and the Australian, almost sending the championship leader into the wall. Front wing damage was sustained by Norris, although it was manageable.
The stewards took a quick look and decided no action was needed, as did McLaren when a furious Piastri questioned the move over the radio which, ultimately, saw his title lead reduce to 22 points.
Piastri was the most vocal he has been in his F1 career over the radio, putting McLaren on the spot over whether that was how it wants to go racing.
With contact having been made by Norris to make the overtake happen, it has opened the door to further aggressive moves by either driver on each other for the remainder of the year.
It has made it feel inevitable that another collision will happen, something which can perhaps be pinned to McLaren having intervened on so many occasions this year through the use of team orders.
Winner - George Russell
George Russell had the worst start imaginable to the Singapore GP after he crashed in second practice, costing him valuable track time.
Even during final practice and the first part of qualifying Russell remained unhappy in Mercedes' W16, before everything suddenly came together. Russell was in a league of his own in Q3, setting two laps which were both good enough for pole position.
He made a strong start to the race and was largely unseen for the 62-lap event, due to having led so comfortably to take a second win of 2025. It has given Mercedes breathing space in the constructors' standings, as it now holds a 27-point advantage over Ferrari in the fight for second.
Hot and humid conditions are usually a recipe for disaster for the Silver Arrows, yet Russell and Kimi Antonelli – he finished in fifth – showed great and consistent pace.
Mercedes themselves are unsure why the car worked so well in conditions it usually hates, but it is at least now a positive problem to solve ahead of the North American double-header.
Loser - Ferrari
Ferrari's struggles continued in Singapore, with a major brake failure for Lewis Hamilton having cemented yet another weekend to forget for the Scuderia.
At a venue where Ferrari often show good pace, Hamilton and Charles Leclerc were both unable to challenge the top five, securing sixth and seventh on the grid, respectively.
In the race, the top four quickly escaped the Ferrari duo, who jostled Antonelli for fifth across the bulk of the grand prix.
However, in the closing laps, Leclerc and Hamilton both encountered brake issues, the seven-time world champion's to the extent he had to cut the majority of corners due to being unable to slow his SF-25.
It resulted in a post-race five-second time penalty, demoting Hamilton to eighth – Leclerc finished sixth.
Ferrari remain third in the standings but just eight points ahead of an improved Red Bull, putting the Maranello-based squad at a real risk of falling into a distant fourth should it fail to make progress in the closing rounds.
Winner - Max Verstappen
While Verstappen painted a frustrated figure after the Singapore GP, he is without a doubt a winner of the weekend. Why? The Red Bull worked at its bogey track.
Red Bull has struggled at the Marina Bay Circuit during the current regulations, with the weekend having been judged as pivotal to Verstappen's title chances.
Verstappen converted second on the grid into second on the podium, but insisted he had to win to remain in the title fight.
That would have helped the Dutchman's pursuit of the McLaren duo; however, finishing ahead of both Norris and Piastri at what is a bad track for Red Bull historically, is a very good sign.
A new front wing worked well, as did the new floor which was introduced in Monza. It was also confirmed by Red Bull that it has more upgrades for the final races.
With the RB21 having worked in Singapore, it should now be able to compete for victory in the remaining six races, meaning Verstappen could very possibly overhaul his 63-point deficit
Loser - Williams
Williams did manage to salvage a point in Singapore courtesy of Carlos Sainz finishing in 10th, but it could have been so much more for the Grove-based team.
Alex Albon and Sainz had qualified in 12th and 13th, before it was announced that both drivers had been disqualified from the session.
During post-qualifying FIA checks, it was discovered that both cars exceeded the maximum limit of 85 mm on both sides of the rear wing outer area, resulting in a slam-dunk disqualification.
Sainz started from the back of the grid and did well to recover to 10th, while Albon started from the pit lane following further changes.
The team is set to investigate the cause of the rear wing issue on both cars, with it having left team principal James Vowles bitterly disappointed.
