The upcoming IndyCar season will see the introduction of several different safety enhancements. The NTT IndyCar Series has recently unveiled the technical details of these new components that will be utilized in the 2024 season. Various areas of the car will receive upgrades, each offering unique benefits such as improved crash safety, enhanced visibility, and increased driver comfort.
One of the most noticeable changes will be the incorporation of LED lights into the rear wing endplates. These lights will be positioned facing backward, aiding the driver in assessing the distance to the car in front, especially in wet race conditions where visibility is compromised by road spray. Additionally, the rear attenuator, which already features a red light in its center, will now be further enhanced by these new lights, providing a clearer indication of the car’s edges.
Furthermore, the addition of new cooling vents in the protective Aeroscreen will greatly benefit drivers during demanding race conditions. These vents, located near the top and bottom of the polycarbonate screen, will direct a significantly larger amount of air towards the driver and facilitate the expulsion of hot air from the cockpit. By addressing the issue of stagnant air, which has been a concern since the introduction of the Aeroscreen, drivers will experience improved safety and comfort, particularly during the peak temperatures of summertime races. The updated screen with these vents will be introduced at the IMS road course race in early May and will be utilized for the remainder of the season on road and street courses.
From a technical standpoint, IndyCar is also implementing new regulations regarding the attachment of wheels to the cars during accidents. These changes are a direct response to Kyle Kirkwood’s crash during the recent Indianapolis 500, where his wheel became detached and flew over the catch fencing. All cars will now feature a reinforced rear upright, and the wheel tethers will be mounted to this new component instead of the caliper attachment studs. Additionally, stronger wheel bearing retaining nuts, introduced midway through last year, will now be utilized for all four wheels, not just the rear ones.
Collectively, these new updates aim to provide a safer racing environment for both drivers and fans. Furthermore, the highly anticipated introduction of the hybrid powertrain in the middle of the season will bring about significant changes for drivers and teams, marking a pivotal moment in the championship.
