12 months ago, Fernando Alonso won the event in Belgium alongside two other former Formula 1 drivers Sebastian Buemi and Kazuki Nakajima. This time, they're forced to line up in second as the other Toyota team dominated proceedings in yesterday's qualifying.
Bruno Senna, Jean-Eric Vergne, Pastor Maldonado and Anthony Davidson are also amongst the other past Formula 1 drivers on the entry list.
Alonso's team are close to sealing a WEC title victory. A win in Spa would mean they only need to finish fourth at Le Mans to lift the championship.
