Karl Rebay is a developing driver in his first season of racing on record. His rating of 1,174 places him in the developing band, the entry level of drivers consistently in club fields or too new to have accumulated enough results to move beyond entry level. His single recorded start came in the 2026 Zenith Racing Series, where he drove for Grissom Auto Sports.[1]
That sole appearance produced a win and a podium finish, a remarkable result for an unproven driver. More significantly, Rebay defeated several established competitors in that outing: Ren Messinger, an FIA Silver graded driver; Alex Rubenstein, a three-time American Endurance Racing Class 4 champion; Angelo Dinkov, an FIA Bronze graded driver; and Gino Manley, another FIA Silver graded driver. In a debut season, beating drivers of this calibre in a single-race performance is genuinely notable, even if the limited sample size prevents it from reshaping his overall rating. Rebay remains active in racing and continues to develop his career.
