A decision on whether the DRS (Drag Reduction System) on Lewis Hamilton's Mercedes has broken technical regulations at the Brazilian Grand Prix has been adjourned until Saturday morning.
The news comes after a check by FIA F1 Technical Delegate Jo Bauer found that Hamilton's Mercedes W12 car was not in compliance with the rules following qualifying at Interlagos, which saw the seven-time World Champion finish with the fastest time.
The issue stems from the fact that the gap between the two rear wing planes when the DRS is open must not exceed 85mm, while the gap on Hamilton's car was found to be beyond this limit.
As a result, Mercedes were formally summoned before the stewards at 19:15 local time in Brazil for the alleged breach.
More evidence to come
After a lengthy wait, there was confirmation from the stewards that a decision will not be made until Saturday morning as they await further evidence.
"The stewards have adjourned the hearing relating to Document 18 of the 2021 FIA Formula 1 Sao Paulo Grand Prix as they await further evidence that will not be available until the morning," read a statement.
The FIA also confirmed that scrutineering had been completed on the rest of the field with no other rule breaches found, including Max Verstappen's rear wing.
