BrieFly ALONsO KePT IN THe DARK Suffering an inflamed eye, Fernando Alonso kept his sun glasses on throughout Thursday's press conference. While it was no risk to his participation in the Grand Prix he was under doctors orders to avoid artificial light. TAKe A seAT Though not the team's reserve driver, Susie Wolff stepped into Valtteri Bottas' Williams in opening practice. Wolff is set for another outing at Silverstone as well as the post-Austrian GP test. sTICKY sITuATION When Romain Grosjean's engine cover exploded in second pratice, the Lotus team found another use for sellotape. With a new engine cover fitted mechanics made sure it stayed in place courtesy of a roll or two of the engineering fix-all. MeXICAN TRACK DANCe Ahead of the Mexican Grand Prix, reports from organisers claim they sold 100,000 tickets within five minutes of them going on sale and were now looking at ways to add further tickets to meet demand. MCLAReN's DIeT PAINT The revised McLaren paint job was perhaps not simply a matter of giving the team a fresh look. With the metallic flakes in the previous paintwork it emerged the new paint scheme saved as much as two kilograms in weight. The FIA has moved to further clamp down on fuel-flow rates as it looks to close off potential loop holes teams could exploited. At the beginning of the season a technical directive was issued to teams with a revised fuel flow meter implemented from the Chinese Grand Prix which better measured both flow and total consumption after it was suggested at the time that some teams had complex systems to circumvent the meter for short periods. It's alleged some teams had developed systems which accumulated fuel beyond the fuel flow sensor, which was located in the fuel tank, during periods of low demand. That additional fuel was then allegedly used during periods of high demand, therefore injecting it into the engine at a greater rate or higher pressure, which in turn means greater power, than was measured by the meter. In responsehe FIA called for teams to measure fuel pressure at multiple points in their fuel systems, contacting each individually to evaluate how they'd implemented the system. However it's understood the matter reared its head last week at a meeting between the various technical directors prompting the FIA to issue another note in an attempt to clarify things further. "W ith immediate effect we will expect fuel pressure, in the high and low pressure systems, to remain constant above a flow rate of 90kg/hr," race director Charlie Whiting wrote to teams. "We do not consider it necessary to define here what we consider constant, we feel it will be more practical to discuss any concerns we have with the relevant team(s) if and when issues arise." On top of the clarification Whiting also stated that the governing body would again inspect each team's fuel systems to confirm they met the regulations. fia clarifies fuel flow 12 GPWEEK.com // 12 GPWEEK.com // PARTNERS: F1 >>> news
