Christian Horner has reflected on Red Bull’s move to build its own Formula 1 power unit, describing the project as "scary as hell." The in-house engine has gone on to claim its first race wins during the 2026 season.
Horner also recalled an early quip about a "Mercedes" ban at Red Bull Powertrains, amid heavy recruitment from Mercedes during the build-up of the operation.
He had been removed from his role at Milton Keynes after the 2025 British Grand Prix, a year before the engine recorded those first victories.
