The new engine deal between Sauber and Honda has, according to German media, been called off in light of Monisha Kaltenborn’s departure.

The speculation comes from German website Auto Bild.
It is believed that Sauber’s owners ‘Longbow fiance’ didn’t agree with former principal Kaltenborn, who put together the deal. And that this is why she parted on mutual consent.
However, sources close to the situation have said that the original deal was never officially completed, thus Sauber has been able to pull out.
But a spokesperson for Sauber said: “This is purely media speculation, and we do not comment on speculation. Honda’s relationship with Sauber has not changed.”
It uncertain though where Sauber will go if the rumours are true.
One obvious solution would be to stay with Ferrari had hope to get a current spec engine (rather than the year old power unit they run now).
But with McLaren reportedly also in the mix for a Ferrari PU, the more likely option would be to join forces with Mercedes. Especially given they have Mercedes junior driver Pascal Wehrlein.
Renault has also said they would be able to supply a new team next year. However, this is unlikely given that former Renault boss ‘Fred Vasseur’ is expected to be announced as the teams new principal.
