Once again, the new Porsche 911 Carrera adeptly balances its design heritage with a modern look and state-of-the-art performance. This paper examines the advanced aerodynamics of the new 911 Carrera GTS. The integration of the new T-hybrid engine posed significant challenges, including higher demands for engine and hybrid cooling. Moreover, the aerodynamics had to support the car's combination of outstanding performance and everyday usability, all while maintaining the iconic design of the 911. Key focuses of the paper include the optimization of exterior and underbody components to reduce drag and improve driving stability. Solutions such as vertical inlet shutters, an adaptive front diffuser, and detailed aerodynamic refinements help achieve a drag coefficient as low as Cd = 0.27 (Cd_Min configuration, with inlet shutters and front diffuser closed, and the rear spoiler in the ECO position). Nonetheless, the 911 Carrera's performance capabilities are underscored by its ability to lap the Nürburgring Nordschleife in 7:16.9 minutes (best setup including Aerokit with fixed front spoiler and rear wing, inlet shutters, and front diffuser open). The paper also underscores the significant role of computational fluid dynamics (CFD) simulations in the development process. By providing a detailed analysis of these features, the aim is to demonstrate how Porsche effectively combines its storied design legacy with technological advancements to continue the evolution of the 911 Carrera.
