Audi Engine Deficit Exceeds One Second Per Lap, Bortoleto Reveals

Audi driver Gabriel Bortoleto has revealed that the team's engine deficit exceeds one second per lap at certain circuits, making the power unit its primary weakness despite a competitive chassis. The Brazilian, who has scored both of the team's points this season, believes Audi has the infrastructure to fix the issue but cautioned that immediate gains are unrealistic given manufacturing lead times.

Why it matters:

Audi's struggles underscore the steep challenge facing new power unit manufacturers in Formula 1. As the team prepares for its official factory entry in 2026, closing this gap is critical to escaping the midfield. The timeline will directly shape its five-year plan and determine whether the German marque can emerge as a credible threat to the established order.

The details:

• Bortoleto stated the chassis is not yet championship-caliber but is strong enough that a class-leading power unit would have delivered race wins this season.
• The team is eligible for at least two Additional Development Upgrades Opportunities (ADUO), with its raw power sitting at least 4% below the benchmark set by Red Bull Powertrains.
• The deficit varies by track but has been described by Mattia Binotto as exceeding one second per lap, a figure Bortoleto confirmed is accurate.
• Audi developed the power unit entirely in-house, and Bortoleto emphasized that manufacturing lead times make rapid turnaround impossible.

What's next:

Bortoleto remains confident in the project's medium-to-long-term trajectory, noting the team has a clear development plan. With Audi's resources, the focus shifts to eroding the engine deficit through homologation windows, though significant gains will require patience and time.
