Red Bull make key changes for Max Verstappen and Yuki Tsunoda

Red Bull has elected to change the power units of Max Verstappen and Yuki Tsunoda's cars at the Saudi Arabian Grand Prix. 

The world champion and his team-mate have both been equipped with a fresh Internal Combustion Engine (ICE), turbocharger, MGU-H, and MGU-K for the Jeddah weekend, where straight-line speed is vital. 

Verstappen and Tsunoda had only used one example of each component across the first four races, meaning they will not incur a grid penalty for the changes as they take the second permitted component from their allocation of four for the entire season. 

Last time out in Bahrain, both drivers took a fresh energy store and control electronics, putting them on the cusp of a penalty as only two of those components are allowed penalty-free, although boss Christian Horner soothed fears of a potential penalty later in the season. 

Elsewhere, fellow Red Bull Powertrains-powered drivers Isack Hadjar and Liam Lawson sister team Racing Bulls have also been armed with a new ICE, turbocharger, MGU-H and MGU-K, whilst Alpine has also introduced new components.

Both Pierre Gasly and Jack Doohan have been given a new turbocharger, and MGU-H, whilst Gasly also has taken a fresh ICE, and MGU-K. 

Verstappen, Tsunoda, Gasly, Hadjar, Lawson and Haas driver Esteban Ocon have all also taken a fresh exhaust system, with eight of these allowed penalty-free in the system. 

All the changes made are penalty-free, meaning no driver will take a grid-drop for any of the fresh components taken.
