Renault's Vitaly Petrov has said his main target in Malaysia this weekend will be to ensure he goes the distance and finishes his first grand prix.

Petrov, who is making his debut at the pinnacle of the sport this year, failed to finish in Bahrain and Australia and now the youngster is keen to make sure he does all 56 laps at the Sepang International Circuit on Sunday.

"It's a track I know already from GP2 so I won't have to spend time learning the circuit on Friday, which means I can concentrate more on finding a good set-up and evaluating the tyres. I really hope I can finish the race," he confirmed. "That has to be my target because it's important for me to get more miles in the car and experience a full race distance. Robert's result in Melbourne has shown the car has potential and hopefully I can score my first points soon."

As for Australia, while he was disappointed to spin out on lap 9, the Russian added that he still enjoyed the trip to Melbourne and is feeling more and more confident with every lap he does in the R30.

"I liked the circuit and it was quite bumpy and challenging, just like most street circuits. The wet weather also made it interesting and I really enjoyed the first few laps of the race in the damp," he continued.

"It was a shame to retire so early because I think I could have challenged for points in the race - and although I'm disappointed, I still take a lot of positives from the weekend because it's clear that we have a competitive car with a lot of potential.

"I feel like I'm improving each time I get in the car. After two races I now have more experience and a better understanding of how to work with the team to improve the car.

"The R30 is generally well balanced, consistent and stable in the corners, which makes it an easy car to drive, but we still need more overall downforce to get closer to the front. There will be some more aero updates on the car in Malaysia, which should give us a bit more performance. My aim now is to get the maximum from it," he summed-up.
