After the withdrawal of three major manufacturers in a few short weeks in 2009, F1 has been trying to entice more to join the grand prix party.
The idea for the turbo hybrid power units in 2014 was that with road car divisions increasingly turning to hybrids and electric vehicles, but only Honda was enticed enough by the rules, coming in for 2015.
But for 2026, the engine rules are changing once again with beefed-up electrical systems luring Audi in as a works team, Ford as a technical partner to Red Bull's in-house power unit arm, with Honda also re-committing to a full works programme with Aston Martin.
Toyota has been absent from grand prix racing since its 2009 withdrawal, but the Japanese manufacturer has agreed to become a technical partner to the Haas team, with immediate effect.
With the news, RacingNews365 was wondering which global manufacturer you would like to see enter F1?
