The IndyCar Series has introduced aerodynamic and mechanical updates for the 108th running of the Indianapolis 500, particularly focusing on the rear wing downforce potential. Teams can now adjust the rear wing to a nine-degree limit, providing a better compromise between downforce and top speed. Gurney flaps atop the rear wing, in three different widths, are permitted, offering teams flexibility in downforce generation strategies. Additionally, restrictions on trimmed sidewalls at the exit of diffusers and Gurneys on underwing flaps have been enforced to streamline development processes and reduce testing costs for teams. These changes aim to optimize performance while controlling expenses in the highly competitive IndyCar environment.
