One of the hottest debates in recent months in Formula 1 has been whether the new generation of cars, set to debut in 2026, could reach top speeds of 400 km/h. Mercedes team principal Toto Wolff fueled speculation with remarks suggesting this might be possible. However, FIA’s technical director Nikolas Tombazis has firmly dismissed the claims, stating: “There will not be speeds approaching 400 kilometers per hour. It was simply an exaggerated comment.”
Tombazis acknowledged that, in theory, combining reduced drag, high power output, and optimized energy deployment could point toward such speeds. Yet, under current regulations, strict limitations on energy usage make such a scenario technically and physically impossible. He emphasized that FIA always reserves the right to intervene on safety grounds: “The rules do not allow it, and if safety demands, we will step in.”
The first tests of the 2026-spec cars will be held in January at the Barcelona circuit behind closed doors, with no media or spectators allowed. FIA will analyze the data provided by teams while ensuring transparency throughout the process.
Tombazis further noted that performance gaps would be wider at the beginning of the new regulations: “In the early phase, differences between teams will be more pronounced. Some will adapt faster, while others will struggle. That’s part of the game.” He also clarified that FIA does not have access to teams’ engine power figures or wind tunnel downforce data, meaning rumors about who is ahead or behind are mere speculation.
With new entrants to the championship facing steeper challenges, Tombazis stressed that FIA’s current focus lies on car behavior, technical balance, and ensuring drivers have a natural feel at the wheel. Discussions are also ongoing around hybrid energy use, striking the right balance between electric power and combustion engines. As the season approaches, simulator testing is intensifying, with adjustments being made to ensure cars operate smoothly once they hit the track.
