The name of Red Bull's power unit has officially been changed on the FIA entry list, pointing to the increased marketing collaboration with Formula 1 engine supplier Honda.
It was announced back at the Japanese Grand Prix that Honda branding would have increased visibility on the Red Bull cars from the Suzuka race onwards.
A successful Red Bull-Honda partnership officially ended in 2021, with the supplier ending on a high with Max Verstappen's championship-winning finale.
Honda had originally planned to back away from F1 altogether, with Red Bull registering their power supply as RBPT (Red Bull Powertrains), albeit with a technical partnership with Honda, for the 2022 season.
However, the Japanese company's increased visibility now involves a change to the name of the powertrain make, which will be Honda-RBPT in 2023.
With the power unit regulations set to change in 2026, Honda officially registered their interest with the FIA, pointing to a possible F1 return.
