Wolff offers cautious praise for Red Bull's 2026 power unit progress
Toto Wolff has given a rare nod of respect to Red Bull's new in-house power unit project, acknowledging its apparent reliability after the first major 2026 prototype test. He cautioned, however, that true performance levels remain completely unknown.
Mercedes Team Principal Toto Wolff has acknowledged that Red Bull Powertrains appears to have made a strong start with its new 2026 engine, citing impressive reliability during recent private testing in Barcelona. While withholding definitive performance judgments, Wolff's comments mark a rare, qualified compliment to the rival operation that has heavily recruited from Mercedes' own staff.
Why it matters:
Wolff is notoriously measured in his public assessment of competitors, making his direct praise for Red Bull's nascent in-house engine project significant. It suggests that, contrary to some early fears, the Milton Keynes-based team's ambitious venture to become a full works manufacturer is meeting its initial technical milestones, potentially validating its aggressive recruitment strategy and investment.
The details:
- The first major private test of 2026 prototype cars in Barcelona focused on initial reliability checks for the new chassis and power unit combinations ahead of the major regulation overhaul.
- Reports from the closed-door session indicated surprisingly strong reliability across most manufacturers, including Mercedes, Ferrari, and the new Red Bull-Ford partnership.
- Wolff confirmed his team had a "solid three days" but emphasized that no true performance picture has emerged yet, as top drivers were not pushing the cars to their limits during these initial runs.
- Specifically on Red Bull, Wolff noted: "I think they’ve done a good job. [Isack] Hadjar did 107 laps, I believe, on the first day, and was running reliably, so you’ve got to give them that."
- The Mercedes boss tempered any hype about a level playing field, stating the real competitive order will only become clear "when the stopwatch actually comes out."
What's next:
The Barcelona test was merely a first step in a long development cycle. All manufacturers will now analyze terabytes of data to refine their packages. The true performance differentials and reliability under full stress will only be revealed during official pre-season testing in 2026 and the opening races. Wolff's acknowledgment, however, sets an early marker that Red Bull's engine project is a serious undertaking to be watched closely.
