NASCAR Drive is a digital platform that offers immersive experiences for fans, providing access to in-car cameras, team radio communications, and telemetry data. The infrastructure underpinning the platform is critical, with speed being everything to ensure seamless access to realtime data. NASCAR has moved away from long-polling based solutions to using WebSocket-based infrastructure powered by Ably, which allows for dynamic scaling up and down without manual server provisioning. This enables efficient data streaming and reliability features like automatic failover and redundancy. Other motorsports organizations are also leveraging realtime data to enhance fan engagement, such as the NTT IndyCar Series and Formula 1's F1 Unlocked platform. The future of fan engagement is driven by the ability to deliver seamless, dynamic, and highly personalized digital experiences in realtime, with Ably empowering NASCAR to focus on what matters most: bringing the thrill of the race to fans everywhere.
