Welcome to B4Racing

Early Access

B4Racing is in active development. The Post-Session Debrief scenario is fully available, with rally support and additional coaching scenarios in progress.

B4Racing is your AI-powered race engineer. Have a conversation about your racing sessions, get data-driven insights, and receive actionable coaching to improve your lap times.

What is B4Racing​

B4Racing is a conversational AI agent that analyzes your sim racing telemetry and acts as a virtual race engineer. Instead of manually crunching data, you simply chat:

You: "How did I do in my last session at Spa?"

B4Racing: "You completed 12 laps with a best time of 2:18.432. Your consistency was good (1.2% variation), but I noticed you're losing time in Eau Rouge. Would you like me to break down your corner-by-corner performance?"

The agent combines:

  • Data-driven insights from your telemetry and lap times
  • Coaching wisdom drawn from racing literature and proven techniques
  • Actionable recommendations with specific, measurable goals

Supported Disciplines​
