Prost-Senna, Mansell-Piquet and Alonso-Hamilton all qualify under the mutual respect category. Look how Senna behaved when Prost retired at the end of 93, and the message to him through French TV just before he died. There was no one Senna respected more in F1 than Prost as a driver. Alonso and Hamilton the same, whenever they’re asked about each other in interviews its clear they have a lot more respect for each other than they do for Vettel.
As for Mansell and Piquet I remember an interview Keith posted on the site a few months ago, and it was clear they had a lot of respect for each other despite all the rubbish they put each other through when they were teammates. So they probably don’t qualify if you want a harmonious team, but certainly these great drivers were respectful of what the other could do.
Going by your criteria, Fangio and Moss is probably the standout. Clark/Graham Hill and Prost/Lauda as well.
Seems to me many people forget a) Raikkonen-Monotya or b) Raikkonen-MAssa, which surprises me a little, since that was recent. Remember the Ferrari pairing were really good and had a good relationship between them, and Montoya and Raikkonen were to utter aces in 2005 (little strange that they couldn’t get more points in the constructors championship and be con-champions – also they were a better pairing than Alo-Fisichella _and_ with a pretty much faster car MP4-20, but ofc that mercedes engine and car itself was never ever going to be reliable).
Surprised there has only been one mention of Senna-Berger so far. Stewart – Cevert and G Hill – Clark also sprung to mind pretty quickly when I read the first post. I’d also throw D Hill – Prost into the ring, I don’t recall there being any bad blood between those two.
