Aron grew up in Tallinn as the younger brother of sportscar driver Ralf Aron. After winning the CIK-FIA Karting European Championship in 2018, he moved into single-seaters with Prema Powerteam, finishing third in the Italian F4 Championship as the top rookie in 2019. He spent 2021 and 2022 competing in the Formula Regional European Championship, again finishing third in both seasons despite leading the win tally in 2022 with six victories. A step up to FIA Formula 3 in 2023 yielded another third-place championship finish, this time with a race win in Austria after a stellar recovery drive.
Aron was a member of the Mercedes Junior Team from 2019 until late 2023, when he transitioned to the Alpine Academy ahead of his full-time F2 campaign.
Aron secured his seat with Hitech Pulse-Eight for the 2024 season alongside Amaury Cordeel. He immediately showed pace, taking his first F2 podium in Bahrain after charging from twelfth on the grid to third in the feature race. By the Monaco round he had moved into the championship lead, backed by a run of six podiums in seven rounds.
He claimed pole position for the first time in Barcelona, then added further poles in Hungary, Belgium, and Qatar, finishing 2024 as the grid's most prolific qualifier. His first outright victory came at Lusail in Qatar, where he inherited the lead when championship rival Gabriel Bortoleto received a time penalty, ultimately crossing the line first after a controlled race from the front.
The season was not without adversity. Engine failures, race-ending collisions with rivals, and a disqualification in the Abu Dhabi sprint for an illegal DRS actuator modification each cost Aron critical points at decisive moments. He entered the Yas Marina finale with a mathematical chance of the title but starting from the pit lane in the feature race following the sprint penalty ended any realistic hope.
Aron finished the championship third with 163 points, one win, four pole positions, and eight podiums, behind champion Bortoleto and runner-up Isack Hadjar.
Before his full F2 season, Aron completed the 2024 post-season test at Yas Marina driving for Alpine, completing 121 laps. Alpine confirmed him as a reserve driver for 2025, a role he extended into 2026. He made free practice appearances during the 2025 Formula One season with Sauber and Alpine, gaining exposure across five different race weekends. At the young drivers' test following the 2025 Abu Dhabi Grand Prix, driving for Sauber, he set the second-fastest time over 126 laps.
Aron made his Formula E debut at the 2024 Berlin ePrix as a substitute for Sébastien Buemi at Envision Racing, finishing both races in the lower points range. The appearance broadened his single-seater experience outside of the FIA pyramid.
Aron's F2 career illustrated both his natural speed — few drivers in the series could match his qualifying consistency across a full season — and the fine margins that separate championship wins from near-misses. Finishing third in F2, F3, and Formula Regional (twice), and third in Italian F4 as a rookie, he accumulated a string of championship bronze medals in junior racing before breaking through to a first F2 victory. His progression to an Alpine reserve role and repeated FP1 outings positioned him firmly on the Formula One ladder heading into 2026.
