Charlie has said an old problem still persists with the F23, that Ferrari are struggling with that allowed LEW to pass him at Mexico, in that the tyres cannot heat up quickly enough and actually hold the required temperature demonstrated more when the red flag happened and put the coup de grace on any effort to move up when he was put on hards for the last stint, another unbelievable bad strat.
It's strange though that this problem actually made SAI get a lucky win at the SGP with a 'lucky dip' set up chosen out of many.
