Lando Norris and Oscar Piastri on brink of F1 grid penalty

Lando Norris and Oscar Piastri are on the brink of an F1 grid penalty, following several engine component changes. 

Both McLaren drivers have been fitted with their fourth and final legal internal combustion engine, turbocharger, motor generator unit-heat and motor generator unit-kinetic. 

Aston Martin's Lance Stroll is also on the cusps of a grid penalty, having moved onto his fourth and final element for the same four engine components. 

In addition to those changes, Piastri has also received his final legal energy store and control electronics, Gabriel Bortoleto is in the same situation for the latter engine element. 

For the McLaren drivers, if they require a new engine element of those named, it will result in a grid penalty.
