FIA Clarifies Toto Wolff's 400 km/h Top Speed Claim for 2026 F1 Cars

FIA single-seater director Nikolas Tombazis has definitively clarified Toto Wolff's sensational claim regarding 2026 F1 power units potentially reaching speeds of 400 km/h. Wolff's comments had generated significant discussion within the paddock about the next generation of Formula 1 cars.

Why it matters

Mercedes team principal Toto Wolff recently suggested that the new 2026 F1 cars could approach 400 km/h when full power is deployed, sparking widespread debate. This potential speed increase, from current cars' approximately 370 km/h, raised eyebrows among drivers and fans, prompting the sport's governing body to address the speculation.

The Details

• Wolff initially told German publication Auto, Motor und Sport that "when full power is deployed, we'll be approaching the 400 km/h limit." He later elaborated, acknowledging the statement was "sarcastic" but technically possible if all energy were deployed on a single straight, leaving no electric energy for corners.
• Nikolas Tombazis, however, stated unequivocally that such speeds would not be allowed. "I can assure you there won’t be speeds of 400km/h," Tombazis told PlanetF1, characterizing Wolff's comment as "light-hearted."
• He emphasized that while combining "power the cars have and with the low resistance" could theoretically lead to high speeds without regulatory limits, the FIA's energy management regulations prevent this.
• Tombazis affirmed the FIA's control, stating they have a "strong card to play if necessary" for safety reasons and would "intervene" if needed.
• This aligns with Max Verstappen's prior assessment that the FIA "won't allow it" when asked about Wolff's claim.

The Big Picture

The FIA's quick clarification aims to manage expectations and reassure stakeholders about the safety and controlled performance of future F1 cars. While technological advancements promise faster and more efficient power units, the governing body maintains strict oversight to prevent extreme and potentially unsafe speeds.
