Vitantonio Liuzzi will become the latest driver to change his chassis this year in a bid to resolve his struggles with the VJM03.
Sebastian Vettel and Michael Schumacher have done the same earlier this year.
Liuzzi will revert back to the car he used in the first four races of the season. As discussed here last week his deficit to Sutil in dry qualifying peaked at over a second in the Turkish Grand Prix.
The last few races have been pretty tough as we’ve been struggling with a general lack of grip that makes it hard for me to give the maximum.
Monaco was OK and I thought we had solved the issues so it was quite frustrating in Turkey that I couldn’t make the most of our new development items.
We’ve put in some long hours at the factory and found some minor damage on the chassis that we picked up in Monaco. We thought we had fixed it but as a precaution we are switching back to the chassis I used in the first four races.
We’ll look at the chassis again back in the factory and see if we can find any other areas we need to address.
Adrian Sutil said he will try Force India’s version of the F-duct – which they call the SRW – in practice again this weekend, having not raced it in Istanbul.
Despite finishing comfortably ahead of his team mate, who did run the SRW in Turkey, Sutil believes the new part is a step forward for the car.
The SRW was a development item in Turkey and we didn’t use it on my car in qualifying or the race as we didn’t get enough information on it after the various issues we had in practice. It’s a really good system for me as I can use it without taking my hands off the steering wheel and once we introduce it long-term it will be very easy to use.
We saw on Tonio’s car that it gave a big improvement, so if we can use it on my car it will be a real step forward. We will test it some more in Canada and hopefully get some good data together.
Reserve driver Paul di Resta will not be driving for the team this weekend but will resume testing duties in the next race at Valencia.
