Michael Schumacher. He won the Australian Karting Championship in 2015 and 2016. Doohan had additional success the next year, finishing third in the
CIK-FIA Karting European Championship and sixth in the
World Championship.
Formula 4 (2018) Doohan started his single-seater career at the age of fifteen in the
F4 British Championship with the
TRS Arden Junior Racing Team, alongside fellow
Red Bull junior Dennis Hauger. He scored three wins throughout the season, with his first car racing victory coming at
Thruxton. Doohan finished fifth in the standings, just one point behind Hauger. That year, Doohan also participated in both the
German and
Italian Formula 4 championships for
Prema Powerteam on a part-time basis. He finished 12th and 20th in the standings respectively, scoring no podiums.
Formula Three (2019–2021) 2019: Debut in Asian Championship and Euroformula In 2019, Doohan made his first appearance in the
F3 Asian Championship with
Hitech Grand Prix. Driving for
Hitech Grand Prix, the Aussie won five races and ended up second in the championship, 25 points adrift of the experienced
Ukyo Sasahara. Doohan's main campaign in 2019 would lie in the
Euroformula Open with
Double R. The Australian finished on the podium twice, once at
Hockenheimring and at the
Red Bull Ring. Other than that, his season was average and Doohan ended 11th in the standings, and sixth in the rookies'. The next winter, Doohan returned to the
Asian Championship with Pinnacle Motorsport. He once again finished in the runner-up spot, this time behind
Joey Alders.
2020: Debut campaign in FIA Formula 3 In 2020, Doohan progressed to the
FIA Formula 3 Championship, driving for
HWA Racelab, partnering
Jake Hughes and
FDA-member Enzo Fittipaldi. Doohan's high point during the season was seventh in qualifying in
Silverstone and topping practice in
Spa-Francorchamps, but mainly his campaign was full of incidents and misfortune. Doohan did not score any points during the campaign, and with a best finish of eleventh place, which came at the final race in
Mugello, he classified 26th in the drivers' championship. Despite describing the year as having been "very very tough", Doohan maintained that he had been able to learn more from it than he would have from a more successful season. He tested for
Trident during post-season testing.
2021: Runner-up to Hauger during the
2021 Spielberg Formula 3 round. For the
2021 season, Doohan made the switch to
Trident to partner
Clément Novalak and
David Schumacher. He started his season off strong with a second place in qualifying in
Barcelona. He scored his first points with eighth in the second sprint race, and despite a slow start in the feature race, Doohan was able to take second and his first podium. Doohan qualified fourth in
France, and drove solid races in the sprint races for eighth and fifth places. He would secure his first F3 victory after overtaking
Dennis Hauger with a few laps to go. At the
Red Bull Ring, Doohan qualified in seventh and finished in the same position in sprint race 1, but was promoted to third place due to numerous penalties from others ahead of him. He would finish seventh in the second sprint but was hit by
Jak Crawford in the feature race, which caused a puncture that unravelled his race. In
Budapest, Doohan qualified third. He had an average first sprint race, finishing ninth but fell back to 13th in the second sprint due to mechanical issues. He bettered that result and took third place in the feature race. The following weekend in
Spa-Francorchamps was where he achieved his biggest success of the campaign. Doohan took his first pole position on Friday by 0.7 seconds. Doohan ended 12th in the first sprint race, in which he revealed he purposely kept his spot to block off
Dennis Hauger behind for reverse pole. Doohan would then control things perfectly and win both the second sprint race and the feature race at
Spa-Francorchamps, even having a battle with
Victor Martins in the latter race. This made him the first
FIA Formula 3 driver to score two victories on the same weekend. He qualified fourth in
Zandvoort and ended sixth in the first race. However, a mistake in the second race at
Zandvoort cost him a heap of points, but he managed to finish fourth in the feature race. Doohan claimed pole in the
final round in Sochi. A mistake by Doohan in the sprint race left him out of the points and Hauger to claim the title. Having defied team orders to let through his teammate Novalak during the race, Doohan won the last race, making sure that
Trident were able to win the teams' championship by a measly four points. Doohan remained in Formula 3 for post-season with newcomers
Van Amersfoort Racing.
FIA Formula 2 (2021–2023) 2021: Debut with MP Doohan joined
MP Motorsport for the final two rounds of the
2021 championship, replacing
Richard Verschoor. He qualified 16th on his debut in
Jeddah, and in the first sprint race, narrowly missed reverse pole by 0.08 seconds. In just his second race, Doohan avoided all chaos for his first points in fifth place. Doohan qualified a brilliant second in the
Yas Marina finale. He once again scored points in the second sprint race, finishing eighth. His feature race ended in disappointment, as he spun into the barrier on the opening lap, ending his race. Doohan ended his partial F2 campaign 19th place in the standings with eight points.

2022 Spielberg Formula 2 round. On 13 December 2021, it was announced that Doohan would join
Virtuosi Racing alongside
Marino Sato for the
2022 championship. His start to the season looked promising, as he would score pole position in the season opener at
Bahrain. Doohan lacked pace in the sprint race and ended where he started. However, a collision with
Théo Pourchaire at the pit exit during the feature race broke his front wing, taking the Australian out of the battle for the lead. He fell down to last but managed to recover to tenth place. Nevertheless, Doohan found positives in his performance, stating that he "[had been] as quick as anyone" during the race. Doohan qualified third in
Jeddah, but unfortunately was disqualified from qualifying due to a technical infringement. He was involved in a race-ending collision with
Logan Sargeant in the sprint race, where Doohan hit the back of Sargeant during a safety car restart, receiving a grid drop. He made another feature race recovery, finishing ninth. Another disastrous round followed at
Imola, where he qualified third for the feature race. After 11th in the sprint race, he would clash with
Dennis Hauger at the start of the feature race, putting him out of the running. Nevertheless, the Australian soldiered on, taking another pole position in the fourth round in
Barcelona. Setting his target towards "[getting] some points on the board" for the feature race, Doohan placed sixth in the sprint race after a good start. He would score his first podium of the season on Sunday, ending up second after being overtaken by championship leader
Felipe Drugovich in the latter half of the race. Doohan qualified fifth in
Monaco, but was promoted to third following penalties. Following finishing seventh in the sprint race, Doohan missed a second podium after he was jumped by
Jüri Vips in the pit stops, settling for fourth place. His top 3 qualifying streak ended in
Baku, securing only 11th. He had another weekend to forget, his sprint race was affected due to a collision, and a penalty for him in the feature race due to contact with
Liam Lawson demoted Doohan to P13. Doohan qualified seventh for the feature race in
Silverstone. In the sprint race, Doohan would take his first victory of the season, fighting his way up to first in the sprint race in wet conditions. Starting on the alternate strategy for the feature race, Doohan continued to score points with ninth. He continued this form by scoring another podium at the
Red Bull Ring. However, the podium would be a distant memory in the feature race as like many others, started on the wets on a drying track. This would be the wrong call and Doohan collected multiple penalties on the way to 19th place. Doohan qualified fourth for the
Paul Ricard round and ended a hectic sprint race in the same position. He stormed into the lead during the feature race start, but was re-passed by
Ayumu Iwasa in the next few corners. Following the pit stops, Doohan would spin trying to pass Pourchaire, and fell to fifth at the flag. In
Budapest, the Australian would win once again, dominating the sprint race on Saturday from reverse pole. However, he had a gearbox failure on the opening lap of the feature race and was forced to retire. After the summer break, Doohan experienced an exceptional round at
Spa-Francorchamps, firstly qualifying fourth. He finished second in the sprint race after a good start, even passing
Ralph Boschung on the last lap. After jumping to second in the start, Doohan would eventually undercut race leader
Felipe Drugovich during the pit stops and claim his first F2 feature race victory. Doohan qualified in second the next week at Zandvoort. and finished outside the points in ninth during the sprint. However, a collision with
Richard Verschoor on a safety car restart left him unable to finish. He scored his third pole of the year at
Monza. He ended sixth in the sprint race but he had another forgetful feature race, a bad start costing him and a subsequent collision with
Jehan Daruvala brought about a premature end to his race once more. Doohan's horrid luck continued into the final round of the year at
Yas Marina, where a loose wheel forced him to retire in the feature race, having finished seventh in the sprint race. He ended up sixth in the drivers' standings with 128 points, three wins, three poles, four fastest laps and six total podiums.
2023: Third in championship Doohan partook in the 2022 post-season test, remaining with
Virtuosi. Soon after, he was confirmed to continuing his relationship with the British outfit for the
2023 campaign, alongside
Amaury Cordeel.
Virtuosi Racing during the
2023 Spielberg Formula 2 round. Doohan had a terrible
opening round in Bahrain, a poor qualifying in 17th would not reward him with any points. The Australian was back on form in
Jeddah, qualifying P4 and securing his first points of the season with seventh in the sprint race. In the feature race, Doohan made the most of mistakes from the leaders, and secured a second placed podium. In his
Australia home race, a late red flag saw Doohan down in 15th for qualifying, having topped practice. He had a disappointing sprint race after being spun out by
Juan Manuel Correa, but achieved eighth place in the feature race although more points was inevitable without an early safety car. The Australian had another disheartening weekend in
Baku, an incident in the sprint and P16 in the feature race summarised another point-less weekend. In
Monaco, Doohan qualified in fourth and his sprint race was rather uneventful, ending in sixth place. In the feature race, he was running in fourth and set for a big haul of points until he crashed mid-race at Massenet corner.
Barcelona saw Doohan back in the top-three for qualifying. He would claim fifth place in the sprint race, but fell back in the feature race for sixth place. In
Austria, Doohan qualified in fifth. A trip through the gravel ruined his chances of a good result, though he would fight back to seventh place. In the feature race, Doohan improved his place during the start to third, later passing
Théo Pourchaire and was set for second place until a late safety car, where alternate strategy runners
Richard Verschoor and
Ayumu Iwasa passed him, dropping to fourth place. In
Silverstone, Doohan secured fourth in qualifying. During the sprint race, he charged up the order whilst having a tense battle with
Oliver Bearman. The Australian won out the fight, claiming third and his first podium since the second round. He had a solid feature race, finishing fourth during a hectic race. In
Hungary, Doohan made his mark by securing his first pole of the year. During the feature race, Doohan would go on to dominate the race, taking his maiden win of the season by nine seconds. In
Spa-Francorchamps, Doohan would continue his form by topping practice, but qualified in a disappointing 11th. Doohan improved to fifth in the sprint race During the feature race, Doohan ran the alternate strategy and luck would go his way when the safety car was deployed late on. He pitted and emerged in second place, in which he overcame leader Pourchaire on the second last lap for consecutive feature race victories. Aiming to continue his stunning run of form, he qualified fifth in
Zandvoort. However, he failed to score any points, even failing to complete a lap in the feature race after spinning on a damp track. A messy qualifying in
Monza saw Doohan only 14th, and numerous safety cars in the feature race limited him to only sixth place, knocking himself out of title contention. Doohan took pole position for the final race in
Yas Marina. During the sprint race he gained four places to finish sixth. In the feature race he had a good start from pole position leading until he pitted on lap 10 for the medium tyres.
