With four times world champion Vettel three cars ahead and favorite for his fourth Singapore success on Sunday, Hamilton will be hoping for damage limitation before returning to more favorable tracks. But I think tomorrow if we at least jump one at the start and put some pressure on, we'll get them.
All six drivers from the leading teams were on track in the final thrilling moments of the session - but only Vettel could improve his previous time as the championship momentum swings back towards Ferrari.
Vettel's mood will have been boosted further with Lewis Hamilton having to settle for fifth place on the grid, the Mercedes man in possession of a three-point advantage at the top of the drivers' standings coming into the weekend.
The result left Ricciardo slightly disappointed but the Australian remained confident he could win the race on Sunday. "It's important that we obviously keep that but I have a lot of faith we can stay there all weekend", he said. "I love this track, the vehicle was tricky but it came alive and was getting better and better and better as the night progressed, really happy we got it done", said Vettel.
"We know we still have to work hard to improve [in qualifying] - it is still not where Ferrari and Mercedes is".
"We have still got some improvements to make with the auto".More news: Volkswagen to produce electric version of each vehicle by 2030
Red Bull arrived in Singapore hopeful of making the strength of its RB13 vehicle show around the street circuit, expecting to draw closer to usual leaders Ferrari and Mercedes at the front of the pack.
"The final lap wasn't great but it was pretty close", said Verstappen. Red Bull, however, is restrained by an underperforming Renault engine, whereas Ferrari's power unit is nearly on par with Mercedes'. The vehicle was tricky but was getting better, better and better.
"We were already holding on for dear life.I got everything out of all the laps".
"Here, what I've seen today, Red Bull is outstanding".
"I got everything I could out of the vehicle, everything and more", he added. "I really don't know".
