Bottas urges Cadillac to fix reliability after double Austrian GP retirement

Valtteri Bottas says Cadillac must urgently fix its chronic reliability after both he and Sergio Perez retired from the Austrian Grand Prix within a handful of laps due to brake fires. The double DNF capped a torrid weekend for the new squad and squandered a key chance to test upgrades on the MAC-26.

Why it matters:

As a new constructor, Cadillac desperately needs race mileage to understand its car and unlock recent performance upgrades. Instead, Bottas suffered his third consecutive retirement, leaving the team with unanswered questions and a development programme starved of real-world data midway through the 2026 season.

The details:

• Brake fires: Both cars pulled out at the Red Bull Ring after brakes caught fire early, with Bottas reporting no warning after trouble-free 10-lap runs in practice.
• Root cause: Higher ambient temperatures and reduced cooling airflow in traffic caused the brakes to ignite as early as lap two.
• Friday woes: The weekend was already compromised by an electrical issue for Perez and a front floor tray fire for Bottas caused by a build error.
• Upgrades lost: Cadillac introduced revised brake cooling and other new parts for Austria that showed promising pace, but the retirements denied the team data needed to optimize them.
• Bottas' verdict: "If we don't finish the races, then we can't really learn much out of the car... The priority is now pretty clear in Silverstone. We have to finish the race."

What's next:

Silverstone offers a critical reset for Cadillac. Bottas insists the team must see the checkered flag to accumulate sorely needed data and prove its raw speed can be matched with the reliability required to fight in the midfield.
