In FIA documents, it has been revealed that a new Internal Combustion Engine has been brought for Hadjar, one of four new ICEs allowed for 2026 in only the second round of the championship.

Elsewhere, Aston Martin have also introduced changes to Fernando Alonso's AMR26, including a new energy store unit, and a new control electronics unit.

As well as the ICE, Hadjar's power unit has been fitted with a new turbocharger, exhaust set, and MGU-K.

All of the the elements have four changes allowed throughout the season, apart from the latter, which can only be changed three times.

Hadjar and Red Bull struggled in FP1 in China, with the Red Bull debutant finishing in P13, and teammate only in P8 - 1.8s off the lead Mercedes of George Russell.

The Red Bull has also had a new power unit ancillary component (PU-ANC) introduced, as had the two Aston Martin cars, and Esteban Ocon's Haas.

It was another difficult session for Aston Martin, with Alonso and Stroll down in P18 and P20 respectively.

George Russell's 1:32.741 was enough to put him P1, with teammate Kimi Antonelli just over a tenth behind in second, and McLaren's Norris completing the top three but but five tenths down.

It was another dominant display from the Silver Arrows, with competition around them struggling to keep up.
