Three racers start from the pit lane at Spa.

      Before the Belgian Grand Prix start, elements of the power units were changed on three drivers' cars. Lewis Hamilton, Fernando Alonso, and Kimi Antonelli received a new internal combustion engine, a new turbocharger, and new MGU-H and MGU-K motor-generator units. Additionally, on Hamilton's Ferrari, a new energy store, a new electronic control unit, a new exhaust system were installed, and the suspension settings were changed. The "parc fermé" rules were violated to perform these replacements, so Hamilton, Alonso, and Antonelli will start the Sunday race from the pit lane.
