No less than six drivers face demotion following today's qualifying session as a result of exceeding their engine component allowance.
As expected, Alexander Albon will head to the back of the grid on his race debut for Red Bull, the Thai driver - who takes on Pierre Gasly's previous allowance - having taken on a 4th internal combustion engine (ICE), 4th turbocharger (TC), 4th motor generator unit – heat (MGU-H), 3rd motor generator unit - kinetic (MGU-K), 3rd energy store (ES) and 3rd control electronics (CE).
All the penalties are the result of engine upgrades from Honda, Renault and Mercedes, Stroll being the only Mercedes-powered driver to exceed his limit as he takes on the German manufacturer's latest update.
While Albon and Kvyat are penalised this weekend, Max Verstappen and Gasly will face similar penalties when they opt to take on the spec-4 Honda unit.
