A1 / The Coach

Leon Erger.
Sim-built. Grid-proven.

Most racing drivers spend their childhood in karts. Leon spent his in the simulator — and then proved the pace was real. On his very first professional race weekend, in the ADAC GT4 Germany at the Nürburgring, the #19 Aston Martin he shared qualified in the top three — and finished seventh.

A2 / The Story

A different road to the grid

Leon Erger, from Wiehl in Germany, never climbed the classic karting ladder. His racecraft was built lap by lap in iRacing, where he worked his way into the top 1% of the world. What most people treat as a game, he treated as training — structured, data-driven, and relentless.

After test days on real circuits confirmed the sim pace carried over — with coaching from Mike David Ortmann, the reigning ADAC GT4 Germany champion — the door opened: a seat with PROsport Racing for the remaining four race weekends of the 2023 season, sharing the #19 Aston Martin Vantage GT4 with Raphael Rennhofer. Nearly everything about that first weekend at the Nürburgring was new — the procedures, the traffic, the pit stops. The lap times weren't: second in Friday practice, 0.021 seconds off the top, a top-three grid slot for race one, and seventh at the flag. Sunday's downpour showed the other side of racing — a spin, contact, P18 — and taught at least as much as Saturday did.

A3 / Why This Matters To You

He didn't just make the jump.
He mapped it.

Plenty of coaches can drive fast. Leon knows how he got fast — because he built every skill deliberately, in the same simulator you're sitting in. Braking references, line correction, tyre management, racecraft under pressure: each one was trained, measured, and proven on a real grid.

That's what you get in a session — not vague talent advice, but a repeatable method from someone who has driven your exact road, just a few corners ahead.
