Audi tests 2026 power unit in mystery Barcelona shakedown

Audi's 2026 Formula 1 power unit roared to life on track for the first time in Barcelona, but the German manufacturer kept the details under wraps. A mysterious, blacked-out car circulated the Circuit de Catalunya, sparking speculation about whether it was a modified mule car or the actual R26 contender. The secret shakedown served as a crucial real-world validation for the engine ahead of its official debut.

Why it matters:

• This marks the first on-track running for Audi as a future F1 works team, a significant milestone in their ambitious entry.
• Early testing allows the team to identify and resolve integration issues with the complex new power unit before the hectic pre-season testing period.
• Successfully shaking down the engine builds confidence and momentum ahead of the high-profile official launch in Berlin.

The details:

• The car was a "stripped-back, black machine," heavily disguised to mask its design.
• Mule Car vs. R26: While initial reports suggested a "mule car" (an old chassis with a new engine), F1 regulations prohibit running a 2025 car with a 2026 power unit. This strongly implies the car was actually the 2026 R26, fitted with modified bodywork to hide its true aerodynamic shape.
• Driver Lineup: Both Nico Hülkenberg and Gabriel Bortoleto were reportedly on-site, sharing driving duties to get their first feel for the Audi power unit's torque and power delivery.
• Purpose of the Test: The run was likely conducted under a limited "filming day" to gather crucial data on the electrical and combustion systems, and to troubleshoot any potential integration problems in a private, low-pressure environment.

What's next:

• Audi is set to officially launch its 2026 challenger, the R26, at an event in Berlin on January 20.
• Today's shakedown was a final check to ensure that when the car is finally revealed, the power unit—the heart of the machine—is fully prepared and reliable for the challenges ahead.
• All eyes will now be on Berlin to see the real car and hear more details about Audi's technical ambitions for their F1 debut.
