Bottas: Cadillac F1 Testing Focused on 'Debugging' New 2026 Cars

Valtteri Bottas kicked off Cadillac's official entry into Formula 1 with a shakedown at Barcelona, characterizing the day as a necessary "debugging" process for the radically different 2026 regulations. Despite facing technical issues alongside the rest of the grid, the Finn emphasized that the priority is understanding the new car's behavior and Ferrari's power unit rather than setting lap times.

Why it matters:

This test marks the first real-world validation of the 2026 ruleset, which features lighter chassis and significantly increased electric power. For Cadillac, entering as the grid's 11th team, understanding these nuances early is critical to establishing a competitive foundation. It also serves as the debut for Ferrari's new power unit, adding another layer of complexity to the steep learning curve facing the new partnership.

The Details:

• Car Characteristics: Bottas noted a significant change in driving dynamics, citing reduced aerodynamic load in high-speed corners but a substantial increase in torque exiting corners due to the electric components.
• Power Unit Debut: This session marked the first proper track running for Ferrari's 2026 power unit. Bottas highlighted the challenge of managing battery deployment alongside the new combustion engine characteristics, noting a steep learning curve for the engineers.
• Universal Struggles: The session was held behind closed doors with no lap times released. Bottas revealed that issues were not isolated to Cadillac, suggesting every team is grappling with the "debugging" process of these complex new machines.
• Progress: The team managed just over 30 laps, including installation laps. The primary objective remains transitioning these initial shakedowns into full reliability runs before the season opener.

What's next:

The focus remains on accumulating mileage and ensuring reliability ahead of the Australian Grand Prix. As the five-day test continues, Cadillac aims to ramp up running to validate their package and ensure the new Ferrari power unit can withstand the demands of a race weekend.
