The chaotic Brazilian Grand Prix has created ample
talking points and investigations, and now both Mercedes drivers have been
referred to the stewards for unapproved tyre pressure adjustments.
FIA technical delegate Jo Bauer noted that both drivers
took tire pressure adjustments during the time period during which the race
start was aborted but before it got underway.
Hamilton, Russell under FIA investigation at Brazil GP
The rain-drenched Brazilian Grand Prix faced an aborted
start after Aston Martin driver Lance Stroll beached himself in the gravel on
the formation lap.
In the aftermath, drivers Lando Norris, Yuki Tsunoda,
George Russell, and Liam Lawson all took off on an additional formation lap,
ignoring the procedure that follows an aborted start. All four drivers will be
investigated after the race.
The chaos forced the ultimate start of the race to be
delayed by 10 additional minutes.
More from the Brazilian GP weekend:
During that time period, it came to the attention of FIA
Formula 1 technical delegate Jo Bauer that the Nos. 63 and 44 both had tyre
pressure adjustments during between the 10 minute and five minute signal
pointing to the redone race start.
Bauer noted that tire pressure was released while the wheels
were fitted to the car.
“As this is in contradiction to TD003 N, items 2. c) and 2. h) i., I am referring this matter to the stewards for their consideration,” Bauer wrote in his official referral.
