Mercedes fined for Hamilton fuel temperature breach

Lewis Hamilton’s Mercedes team has been fined by the Singapore Grand Prix stewards after the world champion’s outfit was found to be in breach of Formula 1’s technical regulations.

Mercedes fined for Hamilton fuel temperature breach

A notification from F1 technical delegate Jo Bauer after the opening free practice session said that the fuel that Hamilton planned to use was cooler than is allowed under the rules.

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."

Cooler fuel delivers a performance benefit in terms of power and density, and the FIA has long had a limit of how low the fuel can be taken in a bid to try to stop teams taking things to extremes.

The stewards' verdict said a Mercedes representative explained the breach as the result of an "error in setting the temperature".

Mercedes was thus assessed a fine of 5,000 Euro, the same amount as what was imposed on Alfa Romeo for a similar offence during the Austrian Grand Prix.

How Red Bull endured its second car crash in two weeks

OPINION: Red Bull was justified to be upset that Lewis Hamilton survived his British GP clash with Max Verstappen and went on to win. But its attempts to lobby the FIA to reconsider the severity of Hamilton's in-race penalty were always likely to backfire, and have only succeeded in creating a PR disaster that will distract from its on-track efforts

OPINION: It wasn't just the Verstappen/Hamilton clash that had the Red Bull and Mercedes bosses at loggerheads at Silverstone, with the nature of Formula 1's 2025 engines also subject for disagreement. But hopes to have loud, emotive engines that are also environmentally friendly don't have to be opposed.
