Red Bull Prepares In-house Engine for F1 2026, Horner Optimistic About Keeping Verstappen

Red Bull Racing team principal Christian Horner acknowledges major challenges await his team ahead of the 2026 Formula 1 season — when they begin using their self-developed engine with Ford support.

This in-house engine development program becomes key to retaining Max Verstappen, whose contract with Red Bull runs until 2028. Despite talks with Mercedes, the four-time world champion is expected to stay.

“We understand the pressure that there is next year as a new power unit manufacturer. The challenge is enormous, but we have a hugely capable team and have invested significantly,” states Horner.

Horner emphasizes the advantages of having their own engine development facility — chassis and engine engineers can collaborate directly under one roof. While perhaps not optimal in 2026, benefits will become apparent in subsequent years.

Regulatory discussions continue to ensure balance between engine manufacturers, including possible additional dyno time allocation for teams lagging in engine performance.
