Though it has yet to be officially confirmed, it is nearly certain that among all the various other announcements today, Renault will reveal that it is to stop supplying Red Bull with engines after 2018. These engines will be efficient and will have a lower development cost which might lure Aston Martin into Formula1.
Aston Martin CEO Andy Palmer said in Singapaore this weekend that his company is open to further expanding its relationship with Red Bull Racing.
"And with that independent engine - with that destination in mind - obviously it would make sense for us to increase our participation even as soon as next year". "If we get a reasonable regulation that brings down the cost of the engine, Aston would like to be involved in the engine", added the Briton.
Again, Palmer confirmed: "We'd like to be involved a little more next season and then join the dots".
"We want to be more involved in the sport", he told the pair as part of the Channel 4 race broadcast.
The team now run Renault engines under Tag Heuer branding.
With Honda leaving McLaren for Red Bull-owned Toro Rosso, that deal allows Red Bull to evaluate the Japanese manufacturer's performance next season with a view to subsequently using their engines too.
The prospect of Aston Martin powering Red Bull Racing from 2021 flies in the face of pundits' theory that Porsche could return to F1 with the Milton Keynes-based team, either as an engine supplier or as an fully fledged team after buying Red Bull.
Honda has struggled to get to grips with the part-electric, part-petrol engines since returning to the sport in 2015, while Red Bull and Renault have always been at odds during the hybrid era.
Palmer said he hopes the 2021 engine regulations - which many hope could bring back noise, drama and excitement to Formula 1 - to be finalised as early as the end of this year.
