Three drivers handed grid penalties for Bahrain GP in Malaysia

Isack Hadjar, Arvid Lindblad and Franco Colapinto will all start Sunday's Bahrain Grand Prix at Sepang from down the order after taking grid penalties for exceeding their season's power unit component allocations.

Hadjar has fitted a seventh internal combustion engine of the campaign, one more than the five permitted under his pool, triggering a grid drop for the Red Bull driver. 

Lindblad's situation is more severe. 

The RB driver has taken a fifth ICE, exceeding his five-unit allowance, and has also introduced a fifth turbocharger and a fifth exhaust system, both beyond his four-unit limits in those categories. 

The combined excess pushes Lindblad's penalty total past the 15-place threshold that forces a driver to the back of the grid regardless of further stacking, meaning the teenager will start Sunday's race from the rear.

Colapinto also arrives in Malaysia with a fifth ICE beyond his five-unit allocation, adding a further grid penalty on top of a separate sanction already applied to the Argentine. 

The FIA stewards ruled Colapinto predominantly to blame for a lap-36 restart collision at the Azerbaijan Grand Prix, where he locked up into Turn 1, hit team-mate Pierre Gasly and triggered a chain reaction that also put Lando Norris into the wall, ending all three cars' races in Baku. 

Because Colapinto retired before the original 10-second time penalty could be served, it was converted into a five-place grid penalty for Sepang, stacking with his engine-related drop.
