In the eighth Grand Prix of the season, Max Verstappen and Sergio Perez opt for a new internal combustion engine (ICE) in their Red Bull. The FIA announced this during the first free practice session. It is only the first time for both drivers to have a new ICE fitted in 2023.
Verstappen and Perez also received a new turbocharger. The MGU-H and the MGU-K were also replaced. Again, this is the first time this season. So there is no grid penalty for the changes.
Also new parts Alonso and Norris
McLaren replaced the ICE, turbocharger, MGU-H and MGU-K for Lando Norris. He is doing this for the second time, but again it is within the regulations. So there is no penalty. Fernando Alonso got a new energy store and a new EC (control electronics) in his Aston Martin. It is the first time the Spaniard has replaced these parts.
McLaren driver Oscar Piastri gets his fourth exhaust system already. Eight are allowed per season.
