Pastor Maldonado believes his Singapore Grand Prix performance shows that Williams has the pace to score more grand prix victories before the 2012 Formula 1 season is over.
Maldonado has not scored a point since his shock win in the Spanish GP in May, but qualified on the front row in Singapore.
After losing two places on lap one, Maldonado was battling with Fernando Alonso for third place before suffering a hydraulic problem and retiring.
Despite that disappointment, Maldonado said his race performance left him full of confidence for the rest of the season.
"I was running quite well. The race pace was decent," he said.
"I'm confident for the next race. We have the pace, we have the potential to be fighting for victory and I hope to have better luck."
Maldonado dropped from second to fourth on lap one, but denied he had been over-cautious in reaction to previous incidents.
"The start was OK but just at the first corner on cold tyres I ran a bit wide, that's why I lost the places," he said.
