In a report from FIA F1 Technical Delegate Jo Bauer, it was revealed that Leclerc’s car weighed exactly 800kg after he returned to the pits – the minimum weight required under the aforementioned regulations.
Given that his front wing was damaged in early contact with team mate Lewis Hamilton, Leclerc’s car was re-weighed with the retrieved endplate and then an official spare front wing, increasing the overall weight to 800.5kg.

When fuel was drained from the car, though, with two litres being removed as per the draining procedure submitted by Ferrari, it dropped to a weight of 799kg – just below the minimum requirement.
Gasly’s car also came in at 800kg during its initial weight check, only for a fuel mass check to be carried out and 1.1 kg of fuel to be removed, again as per the draining procedure submitted by Alpine, meaning it subsequently registered at 799kg.
