Williams disagrees Massa exclusion with genuine data

Williams performance chief Rob Smedley says his team strongly disagree with the FIA’s decision to exclude Felipe Massa over tyre temperatures at the Brazilian Grand Prix.

Williams also saying that, it will appeal the decision, Smedley says the team’s own readings showed nothing like the temperature found by the FIA.

The Brazilian was finished eighth at race but was excluded afterwards because he violated right-rear tyre temperatures and pressures limits, which is checked on the grid before the start of the race. This is a recently introduced procedure, intended as a safety measure to stop teams from running excessively low pressures.

“The notice of appeal that we will make is based around the fact we have three independent temperature readings and all of them say how we are within the limits set by Pirelli and the prescriptions for this event,” Rob Smedley quoted as saying by Autosport.

“They explained to us that this is the reference measurement because it is the FIA measurement so this is the one that counts. The other three we have are of less consequence.”

“If you read the document, the right rear tyre of car 19, Massa, on the FIA IR Gun read 137 degrees.

“We have two independent sensors, the first one is the PT1000 which sits inside the tyre blanket and tells us what the surface temperature is and that one was always in compliance with the regulations.

“The last time we could read it, when they took the set off to the grid, it was about 104 degrees. The next independent measure we have is from the car data, this is a completely independent measure and the right rear tyre of Massa’s car was 105.7C.

“So we have two independent sensors which both say we were in compliance with the regulations and we have data to back that up. In addition, we have had independent correlation from our blanket temperature sensors and car temperature sensors to the FIA guns, which Pirelli did for us after all the fuss with Mercedes in Italy.

“We have also bought exactly the same sensor that the FIA uses and we do random checks throughout the weekend to make sure this does not happen. For us it’s quite critical for us that we understand where his problem is.

“We have three independent temperature measures and none of them give anything like the measure the FIA took on the grid.”

    Sorry Williams but what would anyone expect you to say. You got caught with an over heated tire before the race started, now live with your penalty for trying to beat the system.
