Marussia rookie Max Chilton has said that he will whatever is necessary to preserve the team's tenth place in the constructors' championship, despite having one eye on a perfect finishing record.

The Briton has made it to the end of each of his 18 races to date, establishing a new record for numbers, but is keen to complete the set by seeing the chequered flag at Interlagos as the 2013 season reaches its climax with the Brazilian Grand Prix. His ambition is tempered, however, by the fact that Marussia and Caterham remain locked in battle for the final paying position in the teams' standings.

Marussia, of course, has painful memories of a similar situation a year ago, where it lost eleventh on the road and tenth in the championship as Vitaly Petrov passed Charles Pic five laps from home, and Chilton is keen to avoid a repeat twelve months on. The Briton was Marussia's third driver in Sao Paulo in 2012, while Pic has now swapped camps and moved on to the Banbury team's main rival, and both know how much is on the line.

"For sure, we know how important this weekend is, coming into it," Chilton admitted, "But the worst thing is to start panicking because you start not concentrating on the right things. The best thing to do is treat it like a normal race weekend and try to get the most out of the car. If we can do that, and we can race well, then there's nothing that we can be sad about because we gave it the best shot we can. We've done that every race this year and it's worked. But, with the weather in Brazil, it's never over until that chequered flag."

"Of course, [13th] would help the team and it's the target, so we will go for it and see," Pic responded, "We try to be focused on the races we are on, so it's Brazil this weekend, and we'll give our best this weekend, try to get good results for the team and then we will see what happens."

Chilton, of course, will have his other eye on a place in the record books unlikely to be erased until the calendar expands and someone can find similar reliability.

"It's something I'm proud of, a good achievement so far to finish 18 races," he noted, "I think it's already broken Tiago [Monteiro]'s record of 16, but I'm trying not to look into it... I'm a little bit superstitious [and], if you start looking around, I feel that I will tempt fate.

"[Finishing every race] is something I would quite like to keep up but, obviously, if I'm put in a position where I have to really fight as hard as I can to keep that 13th and screw the 'keeping it on the track', I will do whatever I can to keep that tenth [place overall]. It would be nice if I could finish the race on Sunday, but it's not the end of the world if not."
