Banco do Brasil announced ahead of the Abu Dhabi Grand Prix that it will no longer continue to sponsor Sauber beyond the end of this season amid branch closures back in Brazil. The move has left Nasr’s future in doubt, despite him securing the two points which saw the team finish in tenth place in the constructors’ championship ahead of Manor.
Asked about the prospects for Nasr’s future following the race at the Yas Marina Circuit, Kaltenborn admitted the sponsor situation will play a part in any driver line-up decision.
“His major sponsor took a position which the publicly announced and we obviously accept that,” Kaltenborn told F1i. “It plays into the assessment of course, which we are making still. We still have not come to a decision but we want to resolve it as soon as possible.
"However, it takes more than our side to get that done, so we’re on it and I still hope that we can quite quickly resolve it.”
Pascal Wehrlein has been linked with a move to replace Nasr, with Mercedes believed to have provisionally agreed terms with Sauber if the team were to select the German as team-mate to Marcus Ericsson next season.
