Super GT is one of the most exciting and technically fascinating racing series in the world, yet it often flies under the radar for fans outside of Japan. Known for its intense manufacturer battles, extreme levels of engineering, and cars that look closer to road machines than open-wheel racers, Super GT delivers some of the best wheel-to-wheel racing on the planet.
This blog post breaks down my Super GT Explained mini-series into three clear parts:
Part 1: What Super GT is and how the series works
Part 2: The top-tier GT500 class
Part 3: The diverse and competitive GT300 class
Whether you’re brand new to Super GT or just want a deeper understanding of how the series operates, this guide will get you up to speed.
Part 1: What Is Super GT?

Super GT is Japan’s premier grand touring racing series, sanctioned by the GT Association (GTA). While it originated from the Japanese Grand Touring Championship (JGTC) in the 1990s, modern Super GT has evolved into a highly advanced, manufacturer-driven championship that blends cutting-edge race technology with production-car DNA.
The series primarily races at famous Japanese circuits such as Fuji Speedway, Suzuka, Motegi, and Autopolis, with occasional international appearances. Races are typically longer than standard sprint events and often include mandatory pit stops, tire strategy, and driver changes, depending on race length.
What truly sets Super GT apart is its multi-class racing format. Two classes race on track at the same time:
GT500 – the top-tier, factory-backed class
GT300 – a more diverse class featuring customer teams and multiple regulations
This creates constant traffic, strategic complexity, and nonstop action from green flag to checkered flag.
Another defining element of Super GT is the balance between performance and parity. Strict regulations, testing limits, and balance-of-performance rules ensure that races are often decided by strategy, consistency, and driver skill rather than outright dominance.
Part 2: GT500 – The Pinnacle of Super GT

GT500 is the flagship class of Super GT and represents some of the most advanced GT-style race cars in the world. Despite their aggressive, production-based silhouettes, GT500 cars are purpose-built racing machines underneath.
The class currently features three manufacturers:

Although these cars resemble road-going models, they share very little with their street counterparts. GT500 cars use bespoke carbon-fiber chassis, advanced aerodynamics, and highly developed suspension systems designed specifically for racing.
One of the most interesting aspects of GT500 is its technical alignment with DTM (Deutsche Tourenwagen Masters). For several years, both series shared a common rule set, allowing cars to race across championships and pushing development to an extremely high level.
GT500 cars are known for their incredible cornering speeds, downforce, and acceleration, often rivaling or exceeding the performance of international GT3 cars and even some single-seater categories on certain tracks.
This class is also where manufacturer pride is on full display. Factory teams, works drivers, and intense brand rivalries make GT500 the ultimate battleground for Japanese motorsport supremacy.
Part 3: GT300 – Variety, Accessibility, and Strategy

GT300 is where Super GT truly becomes unique. Unlike GT500’s tightly controlled manufacturer format, GT300 is a diverse mix of car types, regulations, and team structures.
The class includes:

You’ll see everything from Ferraris, Lamborghinis, and Mercedes-AMGs to Toyotas, Subarus, and Nissans sharing the same track. This variety makes GT300 one of the most visually interesting and unpredictable classes in global motorsport.
GT300 teams are typically customer-run rather than factory-backed, placing a greater emphasis on driver lineup, pit strategy, and tire management. Balance of Performance (BoP) plays a crucial role in keeping the field competitive despite the wide range of platforms.
Because GT300 cars are slower than GT500 but still extremely fast, traffic management becomes a major factor. Drivers must constantly navigate faster GT500 cars while battling within their own class, creating nonstop pressure and frequent position changes.
GT300 often produces surprise winners, underdog stories, and some of the closest finishes in Super GT.
Why Super GT Matters
Super GT represents a perfect blend of technology, competition, and accessibility. It showcases manufacturer innovation at the highest level while still delivering close racing and dramatic outcomes.
From the extreme engineering of GT500 to the diverse, strategy-heavy battles of GT300, Super GT offers something for every racing fan. Once you understand how the series works, it’s hard not to appreciate just how special it is within the global motorsport landscape.
If you’re looking for a racing series that rewards precision, adaptability, and long-term racecraft, Super GT deserves a spot on your watchlist.
