Hon Chio Leong (, born 12 September 2001), also known as Charles Leong, is a racing driver from Macau. He is the only local driver to win the Macau Grand Prix twice, albeit in Formula 4 machinery. He currently competes in Lamborghini Super Trofeo Asia, having previously competed in the FIA Formula 3 European Championship.
Leong has participated in his home race six times, winning both the COVID-impacted 2020 edition and 2021 edition for Formula 4 machinery.
Leong prepared for the 2021 Macau Grand Prix by competing as a guest driver in four FIA F4 China Championship races at the Zhuhai International Circuit held from 24 to 25 October. Leong won all four races.
Leong tested in a Formula 4 car when he was thirteen. Since then, he has gained a passion for single-seater racing.
In 2016, when Leong was fourteen, he geared up for his first race in Formula 4 by joining the 2016 F4 Chinese Championship with Asia Racing Team. Leong entered 2 rounds of the championship. At Goldenport Park Circuit, Leong took the pole position in race 1. He would finish fourth and fifth in races 1 and 2 respectively, but retired in race 3. In the Shanghai International Circuit round, he would finish third, first, and sixth in races 1, 2, and 3 respectively, and set the fastest lap in race 2. Leong would be illegible to score points as he was under the age of fifteen. Leong is the 15th youngest F4 race winner.
In the 70th Macau Grand Prix, Leong participated in the first weekendâÂÂs Macau Formula 4 Race which was an invitational round of the 2023 Formula 4 South East Asia Championship, with SJM Theodore Prema Racing. It was LeongâÂÂs first race in the Tatuus F4-T421. Leong qualified fourth, behind Hadrien David. Wet conditions were encountered during the qualifying race, which Leong was able to finish third due to DavidâÂÂs non-classification. Positive momentum continued in the final race, which Leong finished second, behind his teammate Arvid Lindblad.
In 2024, Leong made his first appearance with Miki Koyama in the Lamborghini Super Trofeo Asia with SJM Iron Lynx Theodore Racing. Leong completed the season as the first runner-up in the Pro class. He returned to the series in 2025 for SJM Theodore Racing, with Alex Denning as his teammate, and claimed the Pro title one round early.
<sup>â </sup> As Leong was a guest driver, he was ineligible for points.
