Charles Leclerc rages against Ferrari in untelevised x-rated rant after qualifying disappointment

After Ferrari's strong start to the US Grand Prix evaporated in front of their eyes with a dismal stint in the final qualifying round, Charles Leclerc finally snapped as his patience wore as thin as his tyres.

The Ferrari radios have been as red hot as their liveries this year, as a season that was originally full of hope (amid a title launch from Lewis Hamilton) quickly fell away.

Both Hamilton and Charles Leclerc have been hot on the mic in post-race rants, with Ferrari continuing to live up to the unwanted reputation of having poorly-executed team orders.

Earlier in the season, Hamilton vented his frustration in a furious exchange with his garage, accusing Ferrari of using him as a guinea pig at the Dutch Grand Prix, adding that they were 'wasting' his time.

Now, Leclerc has finally snapped as he fell down the pecking order to fourth in the final stage of qualifying, blaming his tires and front wing control for not securing pole.

Having already sparked controversy this week by clashing with Isack Hadjar, Leclerc was pipped to a front row finish by both drivers in the Red Bull paddock.

But it was only due to tyre wear that Leclerc lost his pace on the last corner of his lap, allowing Hadjar, Max Verstappen, and championship leader Kimi Antonelli to leapfrog him on the time charts.

Ferrari boss Fred Vasseur claimed that they were 'fighting for pole' until the final corner, and that the frustration was felt throughout the entire team.

But Leclerc's reaction was much more animated, as the Ferrari stalwart erupted into an expletive radio message.

"Too much! F***! Too much front wing,” he said.

“The tyres, for f*** sake, such a tiny window.

“It’s s***! It’s absolutely awful. Awful. It’s unbelievable. Crazy."

The rant continued despite interruption from the Ferrari team, as they tried to turn his attention to the lap times.

“I don’t even want to know [the gaps]. The last sector was horrible, with rear locking, rear limited.”

The heated exchange is one of the more damning indictments of the state of the Ferrari garage this year, as frustration has been growing ever since Hamilton's championship challenge fell off.

Still, Leclerc does have some positivity left in his tank.

After cooling off, he claimed that there were a few lucky signs that could make for a strong race.

"The last time I started from fourth here, I won," he said.

On the other side of the Ferrari team, Hamilton has also made headlines as he disagreed with Max Verstappen over the conditions around the fabled COTA track.
