Vettel will expect to be able to exploit it on Sunday.
"In 2015, Singapore provided us with one of the most painful experiences in recent seasons, so we rolled up the sleeves, learned from it and managed to bounce back with a great win past year", said Mercedes team boss Toto Wolff.
"I'm still confident we'll get victory".
Vettel pushed his Ferrari to the limit in his last run, so much so that he ended up touching the wall.
"They say it is more than what we produce with our flights and our cars, which is kind of insane to think".
"I've started second and finished second at this track in the last two years, with fastest lap both times, so my aim this year is definitely to start on pole and try to go one better in the race". "I'm sure it will be close tomorrow but how it will be exactly I don't know".
"I don't know when they went to bed, probably around lunchtime".
Many media reports had said that Renault had told Red Bull the company no longer wanted to supply the team after 2018. "If he can get on the front row, Danny Ric has to be odds-on favourite". "And that is Ferrari and Red Bull".
Vettel has won four of the nine Singapore races so far, and he has another Red Bull driver to beat, if he wants to add to that glowing record. "Seb turned it on in qualifying but I'm looking forward to tomorrow", said the Australian. The battle of the Red Bulls continued, but Ricciardo managed to stay ahead, with Hamilton taking second momentarily. "Since yesterday, we - at least myself - was nowhere near to the Red Bull; today, without some mistakes, we could have [both] been ahead of them".
"A little bit, fine-tuning, but we still have to work hard to improve".
Verstappen lapped the 5 km Formula One track that winds its way through the heart of Singapore in one minute 41.829 seconds. "The vehicle was not quite there where it should be and the Red Bulls seem to be quite a lot quicker, at least at this point of the weekend".
"It's not an easy auto to drive around this track and it seems to be missing the pace as well".
Although Singapore is a night race, the sweltering humidity tests drivers' endurance more than other races as fatigue and dehydration impact on concentration. Get a NOW TV day pass for £6.99!
