The Alfa Romeo Giulia GTA is probably the brand’s most awaited model since FCA started the turnaround of the company with the mid-engined 4C in 2013.

The high-performance model has been a long time coming but the wait is almost over as Alfa Romeo is currently fine tuning parts developed in collaboration with Sauber Engineering. The latest test session at the Balocco Proving Ground was joined by Alfa Romeo Racing ORLEN Formula 1 drivers Kimi Räikkönen and Antonio Giovinazzi, with both getting some time behind the wheel of the Giulia GTA and Giulia GTAm.

The F1 drivers visited the “Autodelta” workshop, the historical Alfa Romeo racing department, before testing the cars to their limits and providing feedback to the engineering team. It wasn’t just a courtesy visit; they worked closely with the engineers, focusing on technical suggestions to optimize aerodynamics and handling.

To complete the fine-tuning of the Giulia GTA and GTAm, Räikkönen and Giovinazzi analyzed the changes made to the car and provided feedback after driving the cars on the track. According to Alfa Romeo, this resulted in a joint assessment of the effects on vehicle dynamics.

Giovinazzi offered tips on the car’s setup, paying special attention to the new carbon fiber components and the wheels with a single locking nut. “It is great to see the improvements we made to the cars today”, Antonio Giovinazzi said at the end of the test session.

As for Räikkönen, he worked with the aerodynamics team on the new appendages added to the new adjustable front splitter and to the new manually adjustable rear wing. Speaking about the overall balance delivered by these new components, along with the diffuser and the underbody fairing, the former F1 world champion concluded: “I find them a perfect mix of everyday use and track use”.

The Alfa Romeo GTA and GTAm benefit from Sauber Engineering’s expertise in carbon fiber components. The Swiss company producing most of the carbon fiber components in the GTA and GTAm, especially those with an aerodynamic impact. These include the new front bumper, the side skirts, the diffuser, the GTA spoiler and the GTAm aero-wing.

As one of the few F1 teams with its very own wind tunnel, Sauber has used aerodynamic research from the wind tunnel to hone components for the Giulia GTAm, including the wing appendages and fully faired underbody. The GTAm’s manually adjustable front and rear wings have been developed to adapt the car’s aerodynamic performance to any kind of track or road, according to the driver’s preferences.

The Alfa Romeo Giulia GTA and GTAm also benefit from a new diffuser that increases downforce for excellent grip at high speeds. On the Giulia GTAm, the high-downforce aerodynamic configuration is able to deliver an impressive lift coefficient, twice as much as the GTA and three times that of the Giulia Quadrifoglio.
