Romain Grosjean optimistic of frontrunning Lotus performance at Hungarian Grand Prix

The Frenchman believes that the twisty Hungaroring will play perfectly to the strengths of the team's E20, which has previously shown strong pace on slow circuits earlier this season.

"It can be a good weekend for us and the circuit has similar characteristics to Montreal and Monaco, where we were competing quite well," said the Frenchman.

"We are bringing some small upgrades to every race and here there are some more. It is a small amount each time, but each time a little bit plus a little bit makes a larger amount. So we have some small updates that should help us and I think we understand the Lotus quite well.

"It should be better for us and if we can have a good balance for qualifying then we can have a good race."

Grosjean had another difficult race in Germany last weekend after damaging his car at the start and finishing down in 18th position.

He said, however, that he has already put the disappointment behind him and is ready to bounce back at the Hungaroring.

"It's another race and another circuit and it is a bit different. We had a very disappointing Hockenheim race, but sometimes a race doesn't go to plan for some reason, so let's jump in the car tomorrow morning forgetting that and knowing that we have a good car so there is no reason that it should be bad.

"You learn form your mistakes and from a difficult race and improve yourself from that point."

Grosjean said that he will not be testing the double DRS system introduced by the team in Germany, and that responsibilities for doing so will rest soley with his team-mate Kimi Raikkonen.

"We had to modify the chassis on top of the air intakes and we could only do it on one car. I had the previous update first on my car and we share the things," he said. "So let's see how it goes here and if it can work even better then maybe we can bring it for the future.

"I think it would be good to work on it even more together and understand it on Friday and see what we can do to prepare it for the second half of the season."
