Liuzzi optimistic over blown diffuser
Vitantonio Liuzzi remains optimistic about Force India's new blown diffuser ahead of this weekend's Hungarian Grand Prix
The upgrade - Force India's version of the low exhaust concept successfully implemented by Red Bull at the start of the season - will be rigorously tested during tomorrow's free practice session.
Liuzzi is confident the new development can improve overall performance of the Force India VJM03, despite the team having only one unit ready for Hungary.
"We are pushing forward with the blown diffuser", he said. "We will use it on one of the two cars tomorrow [team-mate Adrian Sutil's].
"For here, we didn't have enough time to bring that part for both cars and we wanted to see if it worked because it's a really difficult part to make work because of heat shielding and temperature problems.
"We're quite confident that it could be all right but we have to wait and see on Friday and we'll see what will happen."
Force India's previous upgrade, the F-duct, caused the team problems during its debut weekend in Turkey.
Although the blown diffuser has yet to complete a straightline test, Liuzzi is confident that reliability will not be an issue.
"We always brought updates with a reasonably good belief that it works", the Italian said.
