It wasn't a result anyone expected, but Mercedes-AMG Petronas Motorsport Technical Director James Allison applauded a fine result for the team, which extends its lead to 102 points in the Constructors' Championship.
"In the two weeks since the last round of the championship, and in all the hundreds of hours worked and thousands of simulations made, nothing pointed to a result quite like this one," said James.
"Formula One is incredibly complicated, but days like this remind you that it is still a sport - and that you never know what might happen.
"After a difficult weekend prior to Sunday, the manner in which the cards all fell so right for us in the opening corners gave us a massive lift.
"But after that huge dose of luck, it was a relief to show that we had good race pace to justify our good fortune, and we couldn't be more delighted with the way Lewis and Valtteri made the most of it.
"This is a brilliant result for both titles and, of course, we leave Singapore with a spring in our step. But there is still a very long way to go in this championship race."
