Sainz: Red Bull's power unit clearly ahead of Mercedes

Carlos Sainz said the GPS data from Bahrain’s first test day shows Red Bull‑Ford’s power unit is not just a little better, but a distinct advantage over every other team. He echoed Mercedes boss Toto Wolff’s assessment that the Red Bull package sets the current benchmark. While the season is still months away, the early gap is already prompting other teams to rethink their development plans.

Why it matters:

The power unit determines a car’s straight‑line speed, fuel efficiency and reliability, all of which translate directly into race results. A clear lead for Red Bull‑Ford could lock the team into a championship‑winning position before the first Grand Prix, while long‑time front‑runners Mercedes and Ferrari face a steep catch‑up curve.

The details:

• Sainz’s GPS analysis from Day‑1 in Bahrain indicated that Red Bull‑Ford’s engine delivered lap times roughly a second faster than Mercedes‑powered rivals.
• The Spaniard described the advantage as “truly clear,” matching Toto Wolff’s earlier comment that Red Bull’s energy deployment and consistency were “outstanding.”
• Red Bull’s new power unit runs under the 2026 regulations, featuring a higher‑capacity hybrid system and a revised internal combustion engine designed for improved thermal efficiency.
• Mercedes, still adapting its 2026 power unit, reported comparable data but acknowledged Red Bull’s current benchmark status.
• Ferrari’s Sainz praised the package’s reliability, noting that a fast yet dependable engine is essential under the new rules that limit component usage.

What's next:

Mercedes will likely accelerate its upgrade schedule, and Ferrari has already requested deeper telemetry from the Bahrain runs. Red Bull, meanwhile, will aim to convert the testing advantage into race‑day performance as the season‑opening weekend in Saudi Arabia approaches. The next test weekend will be a critical checkpoint for all teams to gauge whether the early gap can be closed.
