I'm glad that Sauber - a C-team - cancelled the deal with Honda (or Honda with Sauber with Vasseur joining Sauber). Even though being patriotic I think that Honda has much more potential with Toro Rosso. In addition, the chance to put their engine in a class A-team like Red Bull maybe in 2019 has much more potential. And Red Bull has proven to be a winning team even with a slower Renault engine.
I don't say they deliberately blew up their engine. But after two frustrating years with McLaren they were thinking about another team and just let 2017 go while concentrating on the next deal, Toro Rosso in 2018.
Can't wait for Adelaide...
