Jenson Button’s grid penalties for the Mexican Grand Prix now total seventy positions after further changes to his engine ahead of Sunday’s race.
The McLaren-Honda driver had already taken two twenty-five place hits for fitting two new engines, turbochargers, MGU-H and MGU-K units this weekend, but will now drop an additional twenty places for the introduction of yet another turbocharger as well as new control electronics and a further MGU-H unit.
Button did not participate in qualifying due to issues with the power unit he used in final practice, with the team unable to revert back to the unit he used in FP1 in time to get him out to qualify.
Button will start twentieth and last on the grid alongside team-mate Fernando Alonso at the Autodromo Hermanos Rodriguez.
