Senna backs split from Dallara

The team announced earlier this week that it was ending its collaboration with Dallara, which helped build its first F1 car after being signed up as part of the original Campos Grand Prix project.

And although the severing of the Dallara ties now means HRT's technical staff is in charge of producing parts and developing the chassis itself, Senna thinks it will ultimately be a benefit for the future.

"The development side of the project is now in our hands," said Senna in Turkey. "Of course it could have been earlier if everything could have been solved then, and it would have been a great benefit for us in terms of performance.

"But now at least we have the tools to start working on the car and hopefully get some performance updates."

Senna, who sat out FP1 in Turkey in favour of Sakon Yamamoto, thinks it will take a few more races before the team is able to make big steps with the car however.

"This weekend is going to be less difficult than Monaco, because the situation is a bit more easy now," he said. "We have more spare parts, and everything is taking a different shape - but it will still be quite hard.

"We have no updates for the car and now the two Virgins have upgraded cars and a few places on this track, like Turn 8, they are going to be quite a bit challenge for us with the stability issues that we still have. We have to work quite hard to keep the gap the same to the other teams this weekend and see if we can find small improvements for the next few races."

When asked when he expected an updated car, Senna said: "We believe that for Silverstone it will be a great, great push - and only if everything goes really well. I think more realistic to expect for the last race before the summer break, which is Germany."
