It must be stressed that this should be still considered rumour, but Missed Apex Podcast understands that the deal had in fact already been signed between Red Bull and Honda, as early as the Monaco GP weekend.
之所以迟迟未公布分析者说：
Firstly Red Bull are still contracted to use Renault power units, but also Honda would not like to be seen to fail a top team yet again should the Canadian Grand Prix upgrade not deliver the required performance and reliability. It is clear that working with a low profile team such as Toro Rosso takes the heat off Honda (unlike working with McLaren!), so this type of methodical planning and deal making can occur unhindered.

Renault are unaware of this, officially, but of course suspect that Honda are in with the serious shout with Red Bull from the rhetoric we've heard in the media, particularly during the build up to the Canadian Grand Prix. Veiled threats on whether the new upgraded Renault power unit would be supplied to their former number 1 team for the race in Montreal. But also the hurry up issued by Renault boss Cyril Abiteboul on Red Bull’s final decision on engine supply. A hurry up that prompted a sharp and telling response from Helmut Marko.
