Mercedes boss Toto Wolff said it was special to conquer "bogey track" Singapore but cautioned the F1 title race wasn't over yet after Lewis Hamilton's "stardust" propelled him to a potentially decisive 40-point lead over Ferrari's Sebastian Vettel.
Team principal Wolff said there was no mystery to Mercedes' form, it was all down to sheer hard work back at the factory and the track.
"Singapore has been our bogey track for several years, so it is a special feeling to come here and win this race on pace," Wolf told reporters after Hamilton's pole-to-flag win and team-mate Valtteri Bottas's fourth place gave them a 25-point lead over Ferrari in the constructors' championship.
"The entire team has worked so hard to understand the car and take steps forward, and this result is an indication that our work is paying off. It was a weekend of many parts: a stardust lap from Lewis in qualifying, a chess game of tyre management this evening, and some nervous moments with traffic and backmarkers during the race," Wolff added.
"It's just the strongest the team has ever been." Wolff warned they had to keep up the intensity to win both drivers' and constructors' championships this season, starting with the Russian Grand Prix in two weeks.
"From our side, we can be pleased with a very solid weekend," he added. "We have leads in both championships, but they change nothing in the mindset of this team.
"We have six weekends to go and we know how quickly the situation can swing back against us. We will take it weekend by weekend, feet on the ground and determined to maximise our potential every time."
