Jenson Button's grid penalty has now hit 70 places ahead of Sunday's Mexican Grand Prix following further changes to one of his latest Honda engines.
In handing Button the new 'phase four' system ahead of first practice at Mexico City, Button initially collected a 25-place penalty with Honda changing the engine, turbocharger, MGU-H and MGU-K.
Prior to second practice, and in order to create a greater pool of units, exactly the same components were changed again, taking the penalty total to 50 places.
Button then failed to take part in qualifying due to a signal system failure that led to a misfire during final practice, forcing Honda to revert back to the power unit used in FP1.
That system, however, has since received a new turbocharger, incurring a 10-place penalty, plus new control electronics and MGU-H, the latter components leading to five-place penalties apiece, resulting in 70 in total.
The punishment matters little, with Button starting on the back of the grid anyway, and with no in-race penalties now applied following a rule change mid-season.
