Renault believe they have the capability to secure fifth place in the Constructors' Standings, despite currently sitting a lowly eighth above only McLaren and Sauber.
The close midfield battle means fifth-placed Williams are just 15 points ahead of Toro Rosso in sixth, with Haas a further five behind in seventh and Renault one point further adrift in eighth, meaning it is all to play for in the final seven races of the season.
Renault's Cyril Abiteboul believes Singapore is a pivotal point in Renault chasing down Williams, so long as both cars can score strongly in the remaining races.
"Williams sit just 21 points ahead of us in fifth place in the Constructors’ Championship and, with seven races to go, it’s very much in our capability to chase that down by the end of the season.
"We need to create some momentum and string together some consistent results with both cars inside the top ten. Singapore will be vital to kick start this effort."
The team's technical chief, Nick Chester, reckons the remaining circuits on the calendar will suit the R.S.17, which has struggled at the lower-downforce circuits such as Baku and Monza.
"We’ve kept improving the car which has been very positive," he commented. "Since Silverstone the car has been a chunk more competitive. Budapest and Spa kept that trend up and we were the fourth quickest car in terms of pace.
"We weren’t as quick in Monza, but the upcoming races should see us back to the level of performance we saw at Spa. There are no remaining tracks with super low downforce. We have good potential to be strong at these next three Asian races."
He added: "It’s [Singapore] massively different to Monza and almost a stark contrast as a high downforce package is required, and that should suit us pretty well.
"There are a number of things to look out for: tight corners, big kerbs and a lot of traction demands, meaning it can be a hard place to get the right set-up. But if you have a reasonable amount of downforce you should have a quick and competitive car.
"We’d expect to be back to our Britain, Hungary and Spa level of performance."
