Sergio Perez has taken new power unit components ahead of the Saudi Arabian Grand Prix.

The Red Bull driver has taken a new energy store (ES) and control electronics (CE) for the second race of the 2023 Formula One season.

No penalty will be issued for the Mexican driver, though he finds himself in a tricky situation for the remainder of the campaign as only two ES changes are allowed over the course of the season, while three CE's are permitted.

Perez is now in a similar situation to that of Ferrari's Charles Leclerc, who was forced into an ES change ahead of the season opener in Bahrain and has taken another unit for this weekend – resulting in a 10-place grid penalty.

Leclerc, alongside team-mate Carlos Sainz and McLaren's Lando Norris, has also taken a second internal combustion engine (ICE) for Saudi Arabia, with three permitted during a season, while both Leclerc and Norris have taken an additional MGU-H.

Norris has seen further changes in the form of a new turbocharger, MGU-K and exhaust system for the weekend in Saudi Arabia.

Max Verstappen leads the championship standings ahead of team-mate Perez after a Red Bull one-two in Bahrain, with Aston Martin's Fernando Alonso third.
