Mercedes’ Lewis Hamilton referred to stewards over fuel temp breach

Marina Bay, Singapore

Singapore Grand Prix – Mercedes’ Lewis Hamilton has been referred to race stewards at Marina Bay over his fuel being allegedly below permitted temperature.

Update: Mercedes have been fined 5000 euro and accepted that the fuel’s temperature was set incorrectly for FP1.

Mercedes’ Lewis Hamilton has been referred to race stewards in Singapore after a notification from the FIA’s Technical Delegate Jo Bauer stated that his car had been detected running fuel cooler than permitted.

The notification came straight after opening practice in Singapore.

The notification said: “The temperature of the fuel intended for immediate use in car number 44, measured at 17:44 with FIA approved and sealed sensor, was more than eleven degrees centigrade (20.3 °C) below the ambient temperature recorded by the FIA appointed weather service provider one hour before the first free practice session (32 °C), this not being in compliance with Article 6.5.2 of the 2019 Formula One Technical Regulations.”

“I am referring this matter to the stewards for their consideration.”

It’s not a particularly serious matter, and isn’t likely to result in any sort of sanction that could affect Hamilton’s weekend. A similar offence was detected in Austria earlier this year, when Alfa Romeo’s Antonio Giovinazzi was detected to be running fuel below permitted temperature. This resulted in a five thousand euro fine for Alfa Romeo, meaning Mercedes are very likely facing the same punishment.

Hamilton finished opening practice in Singapore in P3, 0.6 seconds from the time set by the pacesetter – Red Bull’s Max Verstappen. However, unlike Verstappen, Hamilton didn’t use the Soft tyres to set his fastest time. Both Mercedes drivers used the Hard tyre compound for their best times.
