Jiajun Song is an entry-level professional racing in shared-car endurance championships across Asia. He holds an FIA Silver grade, placing him below the full professional ranks in sportscar racing. Song has made 16 starts across three seasons since 2024, primarily in Lamborghini Huracán Super Trofeo machinery for Leipert Motorsport and latterly for Apex Predator Harmony Racing in the GT World Challenge Asia.[1]
His single podium came in the Lamborghini Super Trofeo Asia Am or ProAm class during the 2024 to 2025 season. Song currently competes in GT World Challenge Asia, where he has made seven starts in 2026 for Apex Predator Harmony Racing. His record against regular opponents is mixed; he runs closely matched with Jiatong Liang, an entry-level professional of similar standing, but typically finishes behind Kai Shun Liu, a professional-grade driver he meets frequently in the same series.[2]
Song has finished ahead of established professionals including Alessio Picariello, a Gold-graded driver with substantial European endurance credentials across the Nürburgring Langstrecken-Serie, European Le Mans Series and GT World Challenge Europe, and Neil Verhagen, a Gold-graded professional with experience in Formula Renault Eurocup, IMSA WeatherTech and GB3. These remain isolated results against much stronger opposition rather than a pattern, and Song's typical position places him mid-field in a shared-grid field of amateurs and professionals.
