Team Lotus test driver Luiz Razia says he is chasing up sponsors for the possibility of making his Formula 1 debut at the season-ending Brazilian Grand Prix in November.

Razia took up an F1 test driver role with Team Lotus after penning a deal to race in Tony Fernandes' Team AirAsia outfit in the GP2 Series, but he has had limited outings in the T128.

However, having seen fellow Team Lotus test driver Karun Chandhok get the opportunity to race at the recent German Grand Prix, Razia is keen to get a similar chance at his home grand prix in an effort to improve his chances of securing a full-time berth in 2012.

Already lined up to drive the car during the free practice sessions, Razia is hoping his sponsors will help him secure an elevated role for the whole weekend.

"It is very difficult for me; no one knows who is Luiz Razia," he told Globo Esporte. "There are 20 Brazilian drivers out there and I think not everyone has a sponsor. If we can change that, a few Brazilians are going to be racing in the future. There is a possibility.

"We are working to get sponsors for next year and it's a situation that also involves other factors. The initial conversation has been going since June. We are working for 2012, but why not start in Brazil? We are in negotiations."
