Lewis Hamilton deliberately driven into by F1 rival in shocking incident – On This Day

The 2017 Azerbaijan Grand Prix will be remembered for many things: Daniel Ricciardo's stunning victory from 10th on the grid, Lance Stroll's maiden podium at the age of 18, Valtteri Bottas recovering from a lap down to snatch second on the final straight. 

But nothing from that chaotic afternoon in Baku resonated quite like Sebastian Vettel deliberately driving his Ferrari into the side of Lewis Hamilton's Mercedes behind the safety car.

It was lap 19. The safety car had been deployed and Hamilton, as the race leader, was controlling the pace of the pack. 

Behind him, Vettel misjudged the Mercedes' change in speed and ran into the back of Hamilton, damaging his own front wing. What happened next was extraordinary.

Rather than drop back and accept the consequences, Vettel pulled alongside Hamilton and turned into him, making wheel-to-wheel contact under caution. It was not a racing incident. 

It was not a lapse in judgement behind a braking zone. It was a deliberate act, carried out while the race was neutralised, and it drew immediate condemnation.

Vettel's punishment

The stewards handed Vettel a 10-second stop-go penalty for dangerous driving, one of the harshest sanctions available during a race. 

FIA telemetry subsequently confirmed that Hamilton had not brake-tested Vettel, as the German had initially claimed, and that the Mercedes driver's inputs were entirely consistent with standard safety car procedure.

Vettel was initially defiant. "I think F1 is for grown-ups," he said. "I think, as I said, the manoeuvre before was not necessary, and obviously damaged my front wing."

He would later soften his stance, publicly accepting responsibility for the incident and expressing regret for his actions following an FIA hearing in the weeks that followed.

In the end, the race itself was decided elsewhere. Hamilton's loose headrest forced an unscheduled pit stop that dropped him out of the lead, while Vettel's penalty cost him any chance of victory. 

Ricciardo inherited the top spot and drove home unchallenged, while Bottas completed one of the great recovery drives, passing Stroll by just 0.105 seconds on the run to the chequered flag. 

That single moment behind the safety car, though, defined Baku 2017, and the rivalry that shaped the season.
