How NASCAR delivers realtime racing data to millions of fans around the world

The NASCAR Drive platform provides second-screen experiences to over 80 million global live racing fans. It offers a live 360 in-cockpit camera feed and access to the same car telematics as the driver and team.

Each NASCAR Cup Series race generates 1.3 TB of high-frequency data (120 updates/second), which is processed and broadcast in realtime to fans. Learn how NASCAR tackles this large-scale realtime data challenge in our interview with Chad Larter, Senior Director of Technical Operations for NASCAR!

What we'll cover

During the interview with Chad, we will discuss:

  • The technical solution used by NASCAR to collect live telemetry data (1.3 TB per race) and distribute it to millions of fans

  • How NASCAR improved data access, expanded features, and increased engagement by bringing the solution in-house

  • How NASCAR solved the data surge and streaming challenges

Key takeaways

If you've watched the video, you know there was a lot to take in, so here are some of the key points covered:

  • Scalability: Tens of thousands of users connect during major races like Daytona 500, with major traffic spikes occurring following in-race events.

  • Data processing: Over 100 data points are collected, filtered and downsampled to 2 updates/second for realtime fan consumption, across devices - 1.3 TB per race.

  • Platform efficiencies: Only changes in data are broadcasted to clients, using binary deltas, reducing bandwidth consumption.

  • Long polling vs Websockets: In comparison to their previous long-polling solution the use of a websockets platform proved much quicker and puts a lot less stress on networks.

  • Shared insights: Fans gain access to the same detailed data used by teams and OEMs, providing a deeper understanding of the race.

  • Fan engagement: Consumers spend significant time (30 minutes to 3 hours) consuming race data, highlighting the success of delivering an enhanced engagement experience.

  • Customization: Fans want to consume data their way, gaining insights on their favourite drivers/cars - not be limited by broadcasters focusing on the leading cars.

  • More to come: NASCAR are exploring the use of realtime data for leaderboards, chat and additional content - moving away from polling methods.
