Citroen will decide within the next two weeks whether it will continue in either the World Rally Championship or the World Touring Car Championship from 2017 onwards.
The French manufacturer has been issued a directive from PSA Peugeot-Citroen's head office to focus on just one motorsport programme starting with 2017.
The decision is set to be one made based on commercial targets and cost efficiency for Citroen.
"In the two following weeks, the decision will be taken about our plans for 2017, I think," said Citroen Racing team principal Yves Matton to wrc.com during the Wales Rally GB last weekend.
Citroen is yet to confirm any of its drivers in either the WTCC or WRC for 2016.
2014 and 2015 WTCC champion Jose Maria Lopez has previously admitted negotiations were ongoing, while four-time champion Yvan Muller told TouringCarTimes he will make his decision after the end of the season.
Sebastien Loeb, meanwhile, is expected to stay with Citroen in the WTCC in 2016, while simultaneously running his own programme, which could expand to three cars.
Loeb's team presently runs two cars for Morocco's Mehdi Bennani and China's Ma Qing Hua.
In WRC, Citroen's two factory drivers Kris Meeke and Mads Ostberg are out of contract as of the season finale and are yet to be formally retained or let go.
