Salvador Duran is savouring one of the finest performances in World Series by Renault history after a crushing victory around Silverstone from fifth on the grid.

Although relatively anonymous throughout qualifying, Duran was on a charge once the lights turned green as he proved the new 3.5-litre machine is capable to overtaking by battling up to the lead of the race on lap 16 and simply streaking away.

The second win of his World Series career, it is however the first time he - along with the Interwetten.com Racing team - have stood on top of the podium since round two of the 2007 season at Monza.

With that in mind, Duran was delighted will the quality of his car having surged to a 13-second victory over Marcos Martinez in just nine laps.

"It has been so good," he told Crash.net Radio. "In the beginning of the race it was difficult because I was trying not to push so hard on my tyres, so I could try and be quick at the end of the race. But, at the end of the sixth lap, the car felt great and I was already third, so I decided to try and attack Barba and after the second attempt I passed him.

"I went after Martinez, who was really quick but when we managed to pass him too and from there were even quicker, so I am very pleased with that.

Even better for Duran, he will start the more lucrative second race from a slightly better position of fourth, leaving him optimistic that he can repeat his feat.

"The car was awesome and everything was working perfectly," the Mexican driver added. "I feel like I have the car to do it (in the second race), so now it is down to the driver and I am feeling confident now!"
