Probably didn't trust Renault to build a PU to get them to where they wanted to be ie podiums and wins. Given their past history, that was a good assumption. Red Bull dumped them for a reason. Hard to say no to a PU that had won the majority of races from the start of the turbo hybrid era.JordanMugen wrote: ↑25 Mar 2022, 15:24I don't really understand why McLaren went from Renault to Mercedes. Renault and Alpine would potentially have offered far opportunities for McLaren to collaborate on wind tunnel, simulators, gearboxes etc.
The Renault power unit itself is obviously a handy bit of kit too, potentially the third strongest!
You are right on the collaboration point but McLaren seems to take great pride in its independence.
