🇨🇿 Jan Koller

Jan Koller, a Czech driver rated 2,596, competes at the developing amateur level; this rating places him among drivers with too few races or consistently limited results to have moved onto the competitive amateur ranks. Across 24 starts in Italian F4 and Euroformula Open from 2024 to 2026, Koller has not recorded a win or podium finish. His average finishing position stands at P20.7, reflecting a career spent in the midfield and back of the grid.[1]

Koller's head-to-head record against his most frequent rivals tells a clear story of outpacing. Against Emanuele Olivieri, a semi-professional rated 3,890, Koller finished ahead only four times in 21 races; against Alex Powell, another semi-professional at 4,183, he was ahead three times in 20 starts. These gaps widen considerably against stronger opposition. Kean Nakamura-Berta, a one-time champion rated 5,296, never finished behind Koller across 18 shared races. Maksimilian Popov, a professional at 4,385, beat him 16 times in 18 encounters. Even among the field Koller has raced, he sits toward the rear. His isolated wins against established professionals such as Hiyu Yamakoshi or Gianmarco Pradel represent occasional strong performances rather than a pattern of beating them.

Koller's career remains based at US Racing, a team with significant resources that has fielded 33 drivers including the elite professional Oliver Bearman. Most of Koller's 11 starts with the outfit came in Italian F4, where he finished 29th in the final 2025 standings after 11 rounds. He stepped up to Euroformula Open in 2026, a more senior single-seater series, but has not yet broken through on that stage. His continued activity suggests he remains committed to the feeder series ladder.
