The last time Nissan entered the legendary race was in 1991 when it entered an R32 Skyline GT-R Group A car.
Nissan has completed over 10,000 kilometres of testing in the lead up to the event and says it is now fully prepared for its biggest challenge of the current season.
The new car's outings in the European-based GT championship are a precursor to a full assault on the series next season.
Its recent entry at the Oschersleben (Germany) FIA GT event was a good simulation for the Spa 24 Hours and its notoriously changeable weather, the car showing a great deal of potential in the tricky conditions.
Equally impressive for the Belgian event is the driver lineup, with Nissan stalwart Michael Krumm (Germany) partnering endurance specialist Darren Turner (UK) and ex-F1 driver Anthony Davidson (UK) in the GT machine.Belgium's Circuit de Spa Francorchamps is one of Europe's most venerable racetracks, with a history to match. The Spa 24 Hours was first run just one year after the famous Le Mans 24 Hours got its start, back in 1924.
