Valtteri Bottas has disclosed a new role in the development of Cadillac’s Formula 1 car, according to GPToday.com.
The report indicates that the Finnish driver, who raced for Sauber from 2022 through 2025, has taken on responsibilities in shaping Cadillac’s 2026 challenger that differ from a conventional driver role. Cadillac entered Formula 1 this season as the championship’s 11th team, joining a grid that also welcomed Audi as a new constructor after the German manufacturer’s takeover of Sauber.
Cadillac’s F1 Entry
The American manufacturer’s arrival marks the first new team entry since Haas joined in 2016. Cadillac operates as a separate entity from Sauber-Audi, fielding its own chassis and running Ferrari power units under the new 2026 technical regulations. Those regulations mandate a major shift in power unit architecture, with electric components now contributing approximately 50 percent of total output, and introduce active aerodynamic systems to the chassis design.
Bottas drove for Mercedes from 2017 through 2021, winning 10 races and finishing as runner-up in the 2019 and 2020 championships. He moved to Alfa Romeo Sauber for 2022 and remained with the team through its transition period leading to Audi’s takeover. The Finn’s experience spans 11 full seasons in Formula 1, including five years with a championship-winning team during the previous generation of hybrid power units.
Technical Development Role
The nature of Bottas’s contribution to Cadillac’s car development represents a departure from standard practice, based on the characterization in the GPToday.com report. Driver involvement in car development typically centers on simulator work, feedback during testing sessions, and collaboration with race engineers on setup direction. A role described as unprecedented suggests either expanded technical input or a formal position beyond the driver-engineer dynamic.
New teams historically face steep learning curves in their debut seasons. Haas, the most recent previous entrant, partnered closely with Ferrari on technical components and took two years to score its first points finish above eighth place. Cadillac’s approach to leveraging Bottas’s decade of experience with established operations could inform its development trajectory as it establishes baseline performance and upgrade paths.
The full scope of Bottas’s role and his specific contributions to Cadillac’s technical program were detailed in the original GPToday.com report. Cadillac’s performance in the opening rounds of the 2026 season will provide early data on how the team’s development structure translates to on-track competitiveness under the new regulations. The next race weekend takes place at Miami on May 4-6.
