"We're really optimistic about it," the Italian explained to reporters in Turkey on Thursday afternoon. "You never know. The team has done a lot of work and has been testing it in the wind tunnel for the last two weeks - it seemed to work pretty well; tomorrow we'll get the full confirmation because, until you're on-track, you never know but we are pretty optimistic that it should be spot on."
Tonio also revealed that, unlike at Ferrari, the Force India drivers will be able to remain in full control of their cars. "We have made a simple system which involves the wrist, so we don't have to take a hand off the steering wheel," he continued. "We have tried many positions but I think that's the easiest and most comfortable one."
