Honda RBPT

Honda RBPT (Red Bull Powertrains) is the power unit division of Red Bull Racing, responsible for designing and manufacturing Formula 1 engines following Honda’s official exit as an engine supplier at the end of the 2021 season. The company was established to maintain and develop the hybrid power units originally engineered by Honda, ensuring Red Bull Racing and Scuderia AlphaTauri continued competitive performance in Formula 1.

History

After Honda announced their withdrawal from Formula 1 at the end of the 2021 season, citing a shift in corporate strategy towards carbon neutrality and sustainability, Red Bull Racing refused to settle for a downgrade in power. Instead, they struck a deal with Honda to take over the intellectual property and continue running the engines under a new entity called Red Bull Powertrains.

The transition was not smooth, with Red Bull having to quickly build infrastructure and hire specialists to maintain and develop the highly complex hybrid turbocharged V6 power units that Honda had perfected.

Technical Overview

Honda RBPT engines are 1.6-liter V6 turbo hybrid power units, featuring:

  • Internal Combustion Engine (ICE): 1.6L V6 turbocharged.
  • Energy Recovery Systems (ERS): Incorporates MGU-K (kinetic) and MGU-H (heat) systems to maximize energy efficiency and power output.
  • Fuel Flow Limit: Governed by FIA regulations, with strict fuel limits and hybrid energy deployment rules.

Despite the name change, the power units are based heavily on Honda’s design and technology. Red Bull Powertrains continues development under FIA’s homologation rules, which freeze major engine changes until 2025, with minor upgrades allowed for reliability and performance.

Performance and Achievements

  • The Honda RBPT engines powered Red Bull Racing to the 2022 Formula 1 World Championship with Max Verstappen, marking a triumphant continuation of Honda’s legacy.
  • The engines are praised for their power, reliability, and integration with Red Bull’s chassis, making Red Bull one of the dominant teams on the grid post-Honda.

Future Developments

  • Red Bull Powertrains is investing heavily in developing a next-gen F1 power unit set to debut in the 2026 season, which will align with new hybrid regulations focusing on sustainable fuels and greater electrical power deployment.
  • The company aims to cement itself as a long-term F1 engine player, expanding its technical prowess beyond the original Honda designs.
