Home driver Yuki Tsunoda enjoyed the spotlight at Suzuka having been promoted from Racing Bulls to Red Bull, while Liam Lawson was sent the other way after just two races of the 2025 season.
The Red Bull RB21s sported a special white livery (main image) to celebrate the team’s final year in its partnership with engine supplier Honda - who will switch to supplying Aston Martin from 2026. But there was plenty more that caught the eye in Japan.

The Honda RA272 was exhibited outside Tsunoda’s garage in the Suzuka pitlane. This was the car with which Richie Ginther took the first win for Honda in F1, at the 1965 Mexican Grand Prix. Red Bull modelled its 2025 Japanese Grand Prix livery on that of the RA272 - but the resemblance between the two cars ends there.

Haas also changed its livery for the 2025 Japanese Grand Prix with an eye-catching cherry blossom motif. The team brought a new floor upgrade (not visible to the naked eye) to the track to improve stability. Pictured are the canards on the edge of the Haas VF-25’s front wing endplates, with an unusual wavy shape. These devices help steer airflow above the front tyres.

Alpine’s F1 car sports long cooling cannons on the side of its engine cover (under the eni logo) that direct airflow towards the rear wing. The air that exits these cooling cannons is hot air that is sucked in by the sidepods, through the radiator and over the engine.

Other teams have opted for square and round airboxes - so it’s not clear why Ferrari has differed in its approach. Above the airbox sits the camera housing from which views of the driver and car are captured and eventually broadcast around the world.

McLaren daubed flow-vis paint along the left-hand side of its car for practice at Suzuka. This paint helps visualise airflow, ensuring the team can match what it’s learned at the factory and in simulations to what’s actually happening trackside.

Red Bull made subtle changes to the exit of its engine cover for reliability. Furthermore it enlarged the rear brake duct casings and changed shrouding around the lower rear suspension wishbones to give the brakes more airflow for cooling purposes.
