Audi draws attention in F1 paddock with unique front brake test. Audi caught the attention of the F1 paddock with an unusual front brake and tyre clearance.

Audi: An unusual test, even by F1 standards

Audi sparked widespread curiosity in the Formula 1 paddock this morning when it sent its car out of the garage fitted with two white components made from an as yet unidentified material, carrying out a verification rarely seen in modern F1 testing.

The two devices were specifically designed to be mounted so that they wrapped around the carbon fibre panel acting as the aerodynamic inlet located on the front brakes. Their dimensions were such that they would deliberately make contact with the tyre sidewall.

Audi’s old-school check intrigues the F1 paddock

By following the live coverage of testing on Sky Sport F1, it became clear that this was a classic, old-style test — typically used in extreme cases when engineers notice, or suspect, that the clearance between the tyre and the carbon panel is too tight.

By fitting the device in question and sending the driver out for a series of laps, engineers can then determine the exact measurement of the gap between the brake duct panel and the tyre under real working conditions. The physical contact leaves precise marks, allowing the team to gather accurate data without relying solely on simulations or sensor readings.

According to Matteo Bobbi and Ivan Capelli, this represents something of an extreme workaround. During these test sessions, no other team carried out a similar procedure. Clearly, Audi had specific concerns it wanted to address, and with the start of the Formula 1 season now fast approaching, this type of verification allowed the team to obtain precise data in virtually no time.

In a championship where millimetres can make the difference between optimal aerodynamic efficiency and unwanted tyre wear, such an unusual solution highlights how seriously Audi is taking every detail as it prepares for the challenges ahead.

In conclusion, Audi’s unusual testing method in Bahrain highlights a pragmatic approach to the 2026 regulations, as the team utilized a “old-school” physical clearance check to gather immediate, accurate data on the spacing between the tire and brake ducts, ensuring reliability ahead of the season opener.
