Fifteen-year-old Noah Killion has claimed the 2025 Motorsport Australia AU4 Championship, sealing the title at Sydney Motorsport Park last weekend.
The Gen2 AGI Sport driver capped off his debut campaign with a decisive performance in the fifth and final round of the season.
After Round 4 in August, Volante Rosso’s Isaac McNeill held a slender four-point lead over Killion on raw points.
Under clear skies at Sydney Motorsport Park, Killion dominated the opening race, taking a convincing victory in Race 1 ahead of Tim Macrow Racing’s Harrison Duske.
The race was interrupted for five laps under full yellow flags following a high-speed collision, when Chloe Lane (Gen2, Tim Macrow Racing) went wide under the bridge and collected Koby Wilson (Gen1, AGI Sport).
Killion then navigated the win in Race 2 despite another five laps under the safety car. The results mirrored Race 1 with Killion, Duske and McNeill finishing first to third.
Race 3 brought further high drama when Killion clashed with Duske at turn 2 while fighting for the race lead. Duske, who was also in the hunt for third place in the Gen2 Championship, was turned around and rejoined in last place, while Killion recovered and started to chase McNeill and Cohen Kokovich (AGI Sport).
Killion snapped up the advantage and worked into the lead with less than four minutes remaining in the race to take the chequered flag.
Post-race penalties to address the clash with Duske reshuffled the order, dropping Killion down the order and moving Brock Burton (Tim Macrow Racing), Imogen Radburn (AGI Sport) and Chloe Lane into the podium positions.
Killion’s results across the round still confirmed him as Gen2 champion ahead of McNeill and Duske.
Killion took to social media following the win, congratulating his fellow racers on a competitive season.
“What an amazing season this has been, with great racing,” Killion stated.
“I’d like to give a huge thanks to my parents for supporting me throughout the season both on and off track.
“I’d also like to thank AGI Sport and more specifically, Timmi, Mark, and Cade who helped me set up the car, look at my data, and coach me through my races.”
In the Gen1 field, Andrew Fitzpatrick (Fitzpatrick Racing) dominated the Sydney round with three wins.
The round podium went Fitzpatrick, Jamie-Lee Su and Koby Wilson. However, Jenson Marold had already secured the Gen1 Championship crown at last month’s SMSP round.
Marold’s title comes with free entry into Gen2 for 2026 and a full test day in a Tatuus F4-TA21.
Killion’s Gen2 victory also means earning a test with a championship-winning team in the United States.
