(REUTERS) - Departing Renault driver Jolyon Palmer says he wants to end the Formula One season on a high after a breakthrough race in Singapore.
The Briton finished sixth under the floodlights for his first points of the campaign, only two days after his team announced that Spaniard Carlos Sainz would be taking his place in 2018.
Some still suspect Sainz could be in the car before the end of the year, but Palmer was adamant he would be staying until the last race in Abu Dhabi.
"The result this weekend is finally a bit of good luck. This result could have come earlier in Baku, Silverstone or Spa. I hope we can build from this in the next six races," he told Sky Sports TV.
"At the moment, the news about Renault is quite fresh. From my side, I want to go out with six of the best races. I want to stay in F1 and there are other options. I want to do myself proud in these six races."
Palmer has limited options, with former champions Williams now the main focus for several drivers hoping to stay in the sport or return.
The top-four teams have all confirmed their line-ups while Red Bull-owned Toro Rosso are expected to replace Sainz with France's 2016 GP2 champion Pierre Gasly, who is already contracted to them.
Fernando Alonso has yet to re-sign, but McLaren are confident of continuing with an unchanged line-up, while Sauber are forging closer ties with Ferrari and seem set to take current Formula Two leader Charles Leclerc.
That leaves Williams, and specifically the seat of Brazilian veteran Felipe Massa, who almost retired at the end of last season.
Poland's Robert Kubica, seeking to return after a 2011 rally accident that seemed to have ended his Formula One career, has emerged as one potential candidate and is being assisted by retired 2016 world champion Nico Rosberg.
Whether Palmer has a hope remains to be seen, but he hoped at least his luck had turned, with German team-mate Nico Hulkenberg suffering reliability problems instead.
"I've had a tough year, we've had reliability issues but I've made mistakes as well," he said.
"The media were always questioning about my future. It's made it a bit harder, but I've learnt to switch off and just focus on the driving."
