Sauber and Manor have joined Force India in requesting an advance on their championship payments for the 2016 season, according to Autosport.
The request has been put to Bernie Ecclestone, but requires unanimous support from all ten teams before the money can be released early.
It’s believed Force India’s request, which was put through last month, has already been approved.
The team sought an advanced payment due to the way in which Formula One Management distributes prize money, which is based on their position in the constructors’ championship from the previous season.
Ten installments are paid monthly through February to November, meaning teams are often left with a cash shortfall during December and January when key development is taking place.
Both Manor and Sauber have now lodged an official request as they are both struggling financially.
