Renault boss Bob Bell says the French squad will approach the final two races of the season aggressively in order to try and secure sixth place in the championship.
Currently Renault is in seventh position with 26 points, 8.5 behind Williams and just two ahead of BMW Sauber. Bell says the team's approach needs to be aggressive in Brazil and Abu Dhabi if it is to beat its rivals.
"We go to every race determined to win and at the very least aiming to finish on the podium, and we're not going to alter our fundamental approach by being defensive to try and protect our position," said Bell. "The only way that we can come out on top relative to both those teams is to take an aggressive approach and try to maximze our finishing positions."
Bell admitted he was sorry the team missed out on a points finish in Japan, despite Fernando Alonso showing strong pace.
"It was disappointing that we came away without any points, especially as Fernando drove a very strong and aggressive race to make up six places," he added. "Ultimately we were hampered by the problems we encountered in qualifying, which meant Fernando started back in 16th place.
"Despite missing out on points, the team still did an excellent job and we can be reasonably satisfied that we got as much out of the race as we could given where we started. Our focus is now on the next couple of races and I believe that if we can qualify well, we can convert that performance into points."
Spaniard Alonso said the team was in a positive frame of mind after the Japanese Grand Prix despite the result.
"Although we didn't get the maximum from the race in Japan, the mood in the team is still very positive. We know that the car is quick, but we were just unlucky in qualifying, which was a shame as I think I could have scored some points if I had started the race in a better position. We know that we have a very tough battle in the championship against Williams and BMW, so any points I can score in the final two races will be very important.
