Vitantonio Liuzzi will revert back to the chassis he drove during the opening rounds of the 2010 Formula 1 season in a bid to turn around a recent run of disappointing form.
The Italian scored in two of the opening four rounds of the season before switching to an updated version of the Force India VJM03 in time for the European summer stint.
However, despite finishing ninth at Monaco, Liuzzi has identified a struggle for grip, particularly during qualifying. His team-mate Adrian Sutil, meanwhile, has scored in the last three events.
Analysis of the chassis has since shown damage picked up during the Spanish Grand Prix, but while the team is confident it has fixed the problem, Liuzzi will change cars for the upcoming Canadian Grand Prix in Montreal.
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,” he said. “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.”
A return to Canada for both drivers, Sutil is keen to put the lessons he's learnt over the last season to good use as he looks to improve his current tenth in the standings.
“I've raced in Montreal twice in 2007 and 2008. I've not had such a good history there so far but I'm older and more experienced now. The first years I went there I think I was a little impetuous and went for a position that wasn't there, but I feel there's a new person going back with more self confidence and understanding.
“I'm really looking forward to the race as I enjoyed Turkey, it was always challenging and, despite it not being the easiest weekend, we still scored points, which shows we can still do well even when the conditions are tough.”
