SPA-FRANCORCHAMPS, Belgium - Williams has promised a full review of it pitstop procedures after a tyre gaffe robbed Valtteri Bottas of the chance to fight for the podium at the 2015 Belgian GP.
Bottas, who had started in third place, was handed a drive-through penalty after the team gave him three soft tyres and a medium at his first stop - an error evident to television viewers given that the tyre walls are colour-coded.
SINCERE APOLOGIES
Performance engineering head Rob Smedley: "As a team we have made a mistake, and on behalf of the team I am very sorry that we cost him what could have been a podium position.
"There will be an investigation into the processes in place to understand what happened fully, and to put in place a procedure to stop this happening again."
Bottas ended up ninth, with Felipe Massa finishing sixth.
Bottas said: "The pitstop and the race pace are two areas that we need to investigate.
"We thought we would be stronger during the race but the soft tyre in the first stint didn't work as well and put us in a difficult position. We have to make sure we bounce back well in Monza."
Williams had hoped for far more at a circuit that favoured their Mercedes engine and in the sort of ideal dry conditions that rarely occur at Spa with its notoriously capricious climate.
Smedley said the first stint dictated the result, with both Williams drivers struggling for pace.
The only consolation for F1's third-placed team was that rivals Ferrari and Red Bull only had one car each in the points.
Smedley said: "We have gained on Ferrari and lost very few points to Red Bull which is positive considering the day we have had."
JUST FOR LAUGHS
Williams have 161 points to Ferrari's 242 and Red Bull's 108. Championship leaders Mercedes are way ahead on 426.
And of course, the internet exploded with banter.
