Lewis Hamilton is set to receive a five-place grid penalty for this weekend’s Austrian Grand Prix after Mercedes was forced to change the gearbox on his car ahead of practice.
Hamilton kicked off the Red Bull Ring weekend in style by leading both FP1 and FP2 for Mercedes, only for his hopes of a second straight Austria victory to be dashed after FIA technical delegate Jo Bauer confirmed the gearbox change.
Gearboxes are required to last six straight events, with Hamilton failing to meet this requirement, forcing Bauer to inform the stewards of the change.
“[Hamilton] did finish the last race in Baku and this gearbox change was before the six consecutive Events expired,” Bauer’s technical report reads.
“As this is not in compliance with Article 23.5a of the 2017 Formula One Sporting Regulations, I am referring this matter to the stewards for their consideration.”
Hamilton will receive a five-place grid penalty once the stewards act, meaning he will start Sunday’s race from no higher than sixth on the grid.
