Several teams made modifications to their cars in preparation for the event . Red Bull introduced a revised version of its RB6 chassis for Vettel as his previous monocoque had a small defect which created handling difficulties in Monaco . The team tested a version of McLaren 's F-duct system ( which increases the top speed of a car ) during the Friday practice sessions but removed it for qualifying and the race because both of McLaren 's drivers found the device difficult to operate . Ferrari modified their F-duct system so that it would allow their drivers to operate the system by using their left leg . Mercedes arrived at the circuit by reverting to a previous specification of suspension and introduced a longer wheelbase on both their cars as well as a new version of their F-duct system . Williams decided to revert to an old specification of their front wing following accidents involving their drivers in Monaco , though the team brought new brake ducts . Lotus débuted a new rear wing specification which improved forward balance of their chassis . Virgin managed to procure a longer-wheelbase version of the VR-01 for Lucas di Grassi after the 2010 eruptions of Eyjafjallajökull prevented them from having two cars prepared in time for the previous race
