Christian Horner says Red Bull securing the F1 Constructors' crown was a true team effort

The Milton Keynes team wrapped up the title at the US Grand Prix last weekend, after Max Verstappen had already secured the Drivers' Championship in Japan.

Horner revealed that it was an emotional race for the team at the Circuit of the Americas as they had learned of Red Bull co-founder Dietrich Mateschitz's passing on Saturday.

"It's been a hugely emotional weekend," said Horner after last Sunday's race.

"When we learned the news yesterday of Dietrich's passing it was very emotional for the whole team, because he was such a giant of a man, and he's done so much, not just for Red Bull Racing, but for F1.

"We felt determined to go out and really honour him in a way that would make him proud.

"So there were no black armbands, there was no minute's silence, there was the embodiment of celebrating him. And the best way to do that, obviously, was the performance on circuit.

"So after eight long years, we've never stopped believing, we've never stopped picking ourselves up, brushing ourselves down, and never lost sight of what our goals and objectives are, which were to get back onto the top of both world championships.

"And we've done that, and that is testimony to the hard work of all of our staff, the contribution of all of our partners, our suppliers.

"And just the spirit that he embodied, that runs throughout all of Red Bull, that has enabled us to achieve what many people would have thought would be impossible."

Asked about how they staved off Ferrari's challenge, Horner added: "I think that the way the team has worked to get together collectively as a group.

"The way that they've supported each other operationally, development-wise, trackside throughout the entire business, and you need every single department doing and playing its role to win a constructors' world championship, and that's exactly what we've had.

"I think that we came very late on to this car, it was heavy at the start of the year, we managed to get a little bit of weight out of it. And with that, we managed to achieve a balance that helps.

"And I think the team has done an incredible job this year, in very difficult circumstances."
