Romain Grosjean is hopeful he can claim his maiden F1 win this season on the back of a very good showing in Bahrain.

Grosjean and team-mate, Kimi Raikkonen both impressed last weekend at the Sakhir International Circuit and with Lotus seemingly on form, the Frenchman believes a victory is a strong possibility in 2012. Indeed following his first F1 points finish in China and then his first F1 podium in Bahrain, he is buzzing with confidence.

"I think winter testing showed us that the car was very good," Grosjean told the official Lotus website, "and the first qualifying in Melbourne was quite amazing being third on the grid. Then I don't think we put everything together in the next races to get the result we deserved. But we knew that we had a very good car, and the team is working very hard as well to bring some improvements and some updates to the car because that will be key to the season.

"But we knew we had something in our hands that was pretty good and worked very well, so now we are trying to make it even better for the next races - we have testing in Mugello and then Barcelona and Monaco - and hopefully if we put everything right then we may get a win before the end of the season."

Despite his optimism though, Grosjean warned they still have some way to go to regularly challenge the likes of Red Bull and McLaren and he said talk of challenging for the Constructors' title was premature.

"It is difficult to say [if we can take the title this year]," he added. "This season will be very tight, but it is not our goal [to do that].

"For sure you want to do the best, but don't burn steps as we say. We are aiming for fourth in the constructors' championship this year - and we are third at the moment so for sure you want do your best to try to keep the position. We are looking pretty good. But we know there is still some work to do to get everything right and to be world champion.

"And why not in the future? That's our goal for sure and we like to be part of this experience, and we'd like to be world champion with this team, it would be nice. We are working hard to achieve that."
