Bruno Senna has admitted he is hoping to be retained by Renault for 2012.
The Brazilian stepped into the black and gold R31 earlier this season to replace Nick Heidfeld, who had been signed as injured regular Robert Kubica's initial substitute.
Senna, 28, has had mixed form during his seven races so far in 2011, describing his season as "interesting" on Brazilian SporTV.
"In terms of learning, it has been very difficult," he conceded on the sports programme Arena.
"I started in the middle and had to learn to use KERS and the moving wing (DRS), and the lack of experience and mileage impaired me a little," said Senna, ahead of his second home race at Interlagos this weekend.
And his thoughts are already set beyond the season finale, with his mother Viviane revealing last week that they are in negotiations with Renault for 2012.
"I have no contract with any team for next year," Senna clarified. "The intention is to stay at Renault," he added, referring to the Enstone based team that in 2012 will be called Lotus.
"In Formula One it is all about performance, and the team is happy with mine."
In a separate interview, he told O Estado de S.Paulo: "I am trying my hardest to stay in this seat.
"It depends on (Robert) Kubica, on (Romain) Grosjean, on sponsorship, a lot of things that, unfortunately, are not under my control.

"We have to get all the factors coming together," the Paulista explained.
On injured Pole Kubica's possible 2012 return, Senna added: "The team isn't going to wait until the middle of next year to decide. I hope it doesn't take too long."
