Oscar Piastri and Franco Colapinto make major changes after huge qualifying crashes

Oscar Piastri and Franco Colapinto have been fitted with new chassis ahead of the Azerbaijan Grand Prix on Sunday.

Both drivers found the barriers during the qualifying session, with Colapinto hitting the wall at Turn 4 during Q1 while Piastri shunted at Turn 3 during Q3.

The McLaren and Alpine teams carried out inspections of the cars after the session and determined they had been damaged beyond repair.

As a result, both drivers had new chassis fitted ahead of the race. Despite the change, neither driver has been penalised.

Article 40 of the sporting regulations grants drivers permission to use a spare survival cell if the previous unit has "suffered genuine accident damage or has suffered a significant failure or fault".

The parts that have been replaced are identical in spec to the damaged components, which is another penalty-free requirement outlined in the regulations.

Piastri will take the start of the race in ninth place, two positions behind title rival and team-mate Lando Norris.

Franco Colapinto will start the grand prix from 16th on the grid.
