Christian Horner Reveals New Details of Controversial 2021 Abu Dhabi GP

The conclusion of the 2021 Formula 1 World Championship remains one of the most polarizing moments in motorsport history, and Red Bull Racing team principal Christian Horner has now shared fresh details about his actions in the pit wall during those critical closing laps. In his memoir, Drive, Horner reflects on the dramatic events of the 2021 Abu Dhabi Grand Prix, openly admitting for the first time that he deliberately lobbied then-FIA Race Director Michael Masi to expedite the safety car restart after Nicholas Latifi’s Williams crashed.

Inside the Final Laps of the 2021 Abu Dhabi Grand Prix

Entering the season finale at the Yas Marina Circuit, Red Bull’s Max Verstappen and Mercedes’ Lewis Hamilton were deadlocked on points. As the race neared its climax, Hamilton held the lead on worn tires, while Verstappen took advantage of the safety car period brought out by Latifi’s incident to pit for fresh rubber. However, five lapped cars sat between the two championship contenders under the safety car, presenting what appeared to be an insurmountable hurdle for Verstappen with so little time remaining.

Reflecting on the realization of that track position, Horner detailed his immediate reaction in his book: “My heart sank,” Horner wrote. “That meant that Max would have to pass all five cars before getting to Lewis, which was impossible in one racing lap.

Facing the prospect of the race ending under the safety car or Verstappen being trapped behind backmarkers, Horner chose to intervene via team radio directly to the race director. Horner documented his radio message: “I decided to apply some more pressure on race control. ‘Come on, Michael, we need to get this race going; why aren’t we getting these lapped cars out the way?’”

The Radio Battle Between Red Bull and Mercedes

Masi ultimately decided to allow only the five cars separating Hamilton and Verstappen to unlap themselves before calling in the safety car, leaving a single lap of green-flag racing. Equipped with brand-new tires, Verstappen quickly overtook Hamilton to claim the race win and his maiden World Drivers’ Championship. The controversial sequence triggered immediate outrage from Mercedes and prompted significant fallout across the sport, leading to Masi being replaced ahead of the 2022 season.

Horner further unpacked the dynamic on the High Performance Podcast, revealing that he had initially refrained from directly lobbying race control until he discovered that Mercedes team boss Toto Wolff was routinely doing so. When Formula 1 began broadcasting team-to-race-control communications during the 2021 season, Horner recognized the tactical advantage Mercedes was leveraging.

“Hang on, that’s not on? You’re putting pressure on the referee here,” Horner said. “So I was like to our team manager, ‘Get me on the line’, because I never spoke to Charlie Whiting in 15 years that he was there.”

Despite the enduring debate regarding how the rules were applied in Abu Dhabi, Horner maintained that Red Bull took advantage of an unprecedented ruling that was fundamentally the race director’s call to make.

“He made the decision, which was within his remit, as per the regulations to be able to do, but it had never been done before, to allow the cars between Max and Lewis to unlap,” Horner said. “It wasn’t our fault but we’re in a position where we’ve got this one lap to have a crack at it, and if anyone is going to deliver you on a lap like that, it’s Max. What happened, happened.”

Why This Matters

The culmination of the 2021 Abu Dhabi Grand Prix reshaped how race control operates in Formula 1. The sheer intensity of team principals directly lobbying race officials during live broadcasts led the FIA to ban direct radio lobbying from team bosses to the race director to protect the integrity of the sporting decisions. While Masi’s controversial handling of the safety car restart led to his removal, Horner’s admissions provide rare inside confirmation that high-stakes psychological pressure from the pit wall played a calculated role in the championship’s dramatic outcome.

Frequently Asked Questions

Why did Christian Horner contact Michael Masi during the safety car?

Horner sought to pressure race control into clearing the lapped cars between Lewis Hamilton and Max Verstappen, recognizing that it would have been impossible for Verstappen to pass five cars and challenge Hamilton for the win in just one lap.

What made Michael Masi’s restart decision controversial?

Rather than letting all lapped cars overtake the safety car—or none of them—Masi allowed only the five cars separating Hamilton and Verstappen to unlap themselves before calling the safety car in immediately. This deviated from traditional safety car procedure and allowed one final lap of racing, enabling Verstappen on fresh tires to pass Hamilton for the title.

Why did Horner start speaking directly to the race director in 2021?

Horner stated that he had never spoken directly to longtime race director Charlie Whiting during his 15-year tenure, but decided to get on the line with Michael Masi once broadcasted audio revealed that Mercedes boss Toto Wolff was speaking directly to race control to influence decisions.
