Esteban Ocon and Kevin Magnussen both could be disqualified from eighth and ninth respectively in the United States Grand Prix for separate incidents.
The stewards have summoned Ocon for allegedly “exceeding the fuel mass flow during Lap 1 of the race at Circuit of The Americas, with a similar issue for Daniel Ricciardo in 2014 seeing the Red Bull driver excluded from second place at the Australian Grand Prix.
Ocon had finished eighth on the road, one position ahead of Magnussen but the Haas driver is also set for an investigation after a report from the FIA technical delegate Jo Bauer.
“Car 20, driver Kevin Magnussen, consumed more than 105kg of fuel, from the time at which the signal to start the race was given to the time the car had crossed the line after the end-of-race signal had been given,” Bauer’s report read.
“As this is not in compliance with Article 30.5 of the 2018 Formula 1 Sporting regulations, I am referring this matter to the stewards for their consideration.”
Magnussen also faces exclusion for such a breach of regulations, having originally picked up two world championship points. Should both drivers be excluded, Sergio Perez would benefit having crossed the line in 10th, while Brendon Hartley and Marcus Ericsson were 11th and 12th respectively.
