Title rivals Max Verstappen and Charles Leclerc will start the Belgian Grand Prix from the back of the grid on Sunday.
The Red Bull and Ferrari stars are two of six drivers to be penalised for using too many engine parts, with McLaren’s Lando Norris another.
Verstappen, who leads Leclerc by 80 points in the championship, set the pace in Friday practice, an eye-opening 0.862secs quicker than Leclerc.
Norris was third, with Mercedes driver Lewis Hamilton in sixth.
Lance Stroll’s Aston Martin, normally outside the top 10, was a surprise fourth ahead of Carlos Sainz’s Ferrari. Fernando Alonso’s Alpine, Mercedes’ George Russell, Daniel Ricciardo’s McLaren and Sergio Perez’s Red Bull completed the top 10.
The other drivers with engine penalties are Alfa Romeo’s Valtteri Bottas, Alpine’s Esteban Ocon and Haas’ Mick Schumacher. (BBC)
