At the end of the 2000s, the Spa 24 Hours shifted from a touring‑car spectacle to the premier gallery of GT3 endurance racing.
From Touring Car Roots to a Global Endurance Stage
The calendar entry appeared in 1964 as a permanent fixture for touring cars and drew the attention of the European Touring Car Championship from 1966 until 1988.
With the Porsche 911 taking three victories during the decade, the distinction between touring and GT cars became blurred; the 1981 Mazda RX‑7 and 1991 Nissan Skyline GT‑R R32 “Godzilla” were both masters of that crossover, overwhelming factory‑backed rivals like the BMW M3 E30.
During the Group A era, manufacturers such as BMW pushed the limits, but the glory of the 1970s never fully returned once Group A regulations fell.
1990s Turbulence: From Super Touring to Group N
Attempts to transplant the rising European GT scene to Spa in 1993 were hampered by expensive, slow entries—a single‑make Porsche Cup that did not excite the crowd.
In 1994, RACB rebuffed sportscars and leaned solely on Super Touring cars, hoping to replicate the Group A charm.
Yet over the decade, these sprint‑optimized machines proved too costly and not designed for 24‑hour stamina, prompting a downgrade to Group N and the production‑based Superproduction category by 1997.
The resulting grids were filled with 220‑horsepower showroom models, which made the races appear unexciting to the public.
2000 – The Launch of an All‑GT Era
Had the 2000s were pivotal when RACB approached the SRO Motorsports Group, inviting them to bring GT racing to the circuit.
With the FIA GT Championship having collapsed its top GT1 class, SRO’s experience and professionalised GT platform were timely.
From 2001, Spa earned a round in the FIA GT calendar and offered doubled points, restoring international respect and drawing manufacturers.
From Lower‑Tier N‑GT to Spectacular GT3
In 2003, a modest Freisinger Porsche 996 GT3 RS from the N‑GT category astonishingly added six laps over contesting top‑tier cars, proving the viability of endurance statistics.
Reliability issues remained high, yet the event’s growth continued, and the event’s reputation rose to that of a headline for GT racing, comparable to Le Mons for Formula 1.
Following the demise of the GT1 World Championship and a failed GT‑2 vision in 2010, the Spa 24 Hours embraced the expanding GT3 classification.
GTA’s SRO now operates the event with over 70 cars, a proportion of which are professional entries, matching the manufacturer presence seen at Le Mans.
Today’s Landscape and What It Means For Endurance Fans
Modern Spa races feature 5 to 8 cars sharing a lap at the end, reducing distance gaps to mere seconds and creating round‑the‑clock competition.
Over the last six editions, distinct manufacturers have captured victory, a testament to the event’s increasingly competitive nature.
With its professional level surpassing even historic touring‑car peaks, the Spa 24 Hours stands as the definitive benchmark for GT endurance racing, a status born from the decisive 2000 gamble and sustained through continuous evolution.
