The FIA stewards initiated an investigation over both Kimi Raikkonen and Antonio Giovinazzi receiving help during the clutch torque application process at the start of the race, or a breach of Article 27.1 of the sporting regulations which states: "The driver must drive the vehicle alone and unaided".
Both drivers were given stop-go penalties for the breach in the regulations, which were converted to 30-second penalties because the race was already over.
The Alfa cars were reported to the stewards by FIA technical delegate Jo Bauer soon after the chequered flag after their race start data was found to not be in compliance.
Kimi Raikkonen and Antonio Giovinazzi had finished seventh and eighth at Hockenheim, but have fallen foul of regulations relating to a driver driving the vehicle alone and unaided.
"The race start data of vehicle numbers 07 and 99 were checked", stated FIA Formula 1 technical delegate Jo Bauer.
Alfa Romeo says it intends to appeal the decision, but if it stands it means Williams has scored its first point of the 2019 season and Hamilton has extended his lead in the championship to 41 points over teammate Valtteri Bottas. "Any device or system which notifies the driver of the onset of wheel spin is not permitted".
But the torque in the clutch must matches the torque demand as the driver releases the clutch at the start within specified limits and this must occur within 70milliseconds. However, the teams have the option to tune some of the controlling parameters. This must occur within 70 milliseconds. But after the race, the race stewards called the team over an alleged breach of Article 27.1, relating to clutch application for the start of the race.
They compared this breach to that of a false start with a potential advantage and therefore opted to give both drivers a 10-second stop-and-go penalty, which equates to 30 seconds added to each of their race times. While the stewards accepted that, they stated no other team suffered the same issue and that the obligation to meet the requirements is irrespective of the climactic conditions.
