Today, the Spa 24 Hours stands as the ultimate GT3 spectacle on the sports car calendar. Yet, this remains a relatively modern phenomenon. Following the race's revival in 1964, it spent nearly half a century as a permanent, iconic fixture of the touring car world.
Naturally, the lines between touring cars and GT sports cars blurred on more than one occasion during that era. The Porsche 911 claimed three victories in the 1960s, and a case could certainly be made as to whether the victorious 1981 Mazda RX-7 was a touring car or a GT machine.
