🏳️ Michael Partenio

Michael Partenio is a developing driver competing in American Endurance Racing, where he has made seven starts across 2023 and 2025. His Racer Rating of 747 places him at the entry level of competitive driving; he races among club and regional-standard competitors, most of whom sit below 2,000 on the scale. His average finishing position of P8.2 across classified results shows he runs in the midfield of the fields he enters, neither regularly at the front nor struggling at the back.[1]

In head-to-head competition, Partenio has faced several repeat rivals. Against Alex Rubenstein, a three-time American Endurance Racing Class 4 champion rated 2,075, Partenio has finished behind him in all four shared races. His record against Nate Vincent, an FIA Bronze graded driver and 2017 Class 3 champion rated 1,997, stands at one win and two losses across three encounters. He has also beaten Edward Henderson twice and Jay Parmenter twice in three-race matchups each, both significantly lower-rated drivers. His single podium finish came in 2025, indicating he remains competitive enough to reach the sharp end on occasion, though consistency has not yet followed.

Partenio remains active in American Endurance Racing as of 2025. With only two seasons and seven races on record, he is still in the early stages of establishing a competitive pattern; the scale and depth of field in his series remain modest enough that his results do not yet demonstrate clear standing among stronger professional or semi-professional drivers.
